Tooltip - demo

View the JavaScript Tooltip demonstration.

Introduction

To begin, create the 3 files needed for this tutorial (index.html, style.css and script.js) and include the stylesheet and the script from index.html. To make things easy the starter files are available by clicking here.

The most important things to remember when writing JavaScript are to keep the code simple and to script logically. The first thing that needs to be established is precisely what you would like the script to accomplish. Based on the desired functionality it then helps to create a diagram or flow description for any complex script before you get into the code. Doing so can help streamline the logic and keep the script clean.

What we are trying to accomplish…

Create a lightweight script that fades a tooltip with rounded corners in relation to the cursor position.

How does the script need to flow…

  1. Setup the namespace and global variables.
  2. Create a function to display the tooltip that takes two variables, the string to display and an optional width integer.
  3. When the function is called build the tooltip markup if it does not exist and register an onmousemove listener to position the tooltip. Insert the tooltip content into the tooltip and call a function to incrementally fade the tooltip to the target opacity.
  4. On the mouseout event of a “hotspot” reference a function that calls the fade function to incrementally hide the tooltip.

Let’s begin by setting up the JavaScript file. We want to create a namespace to encapsulate the functionality of our script. By doing so, we virtually eliminate the possibility of a conflict with some other script or framework.

var tooltip(){
	return{};
}();

Next, we need to add any variables we want to include on the global level of the namespace. By setting these variables globally we can access them in any of the child functions and quickly change them without sorting through the code.

  • id (string) – id of the tooltip
  • top (integer) – number of pixels to offset the tooltip from the top of the cursor
  • left (integer) – offset to the right of the cursor
  • maxw (integer) – maximum width in pixels of the tooltip
  • speed (integer) – value to increment the tooltip opacity during transition
  • timer (integer) – represents the speed at which the fade function in performed
  • endalpha (integer) – target opacity of the tooltip
  • alpha (integer) – current alpha of the tooltip
  • tt, t, c, b, h – these represent global variables to be set later
  • ie (boolean) – global variable based on browser vendor
 var id = 'tt';
 var top = 3;
 var left = 3;
 var maxw = 300;
 var speed = 10;
 var timer = 20;
 var endalpha = 95;
 var alpha = 0;
 var tt,t,c,b,h;
 var ie = document.all ? true : false;

We need to determine how we want the tooltip to look so we can figure out how to build out the elements to add to the DOM… a rectangle with rounded corners on the top and right corners only. To accomplish this we need a wrapper div and then three nested divs. We can style the divs with the CSS. The markup should look something like this once generated.

<div id="tt">
	<div id="tttop"> </div>
	<div id="ttcont"> </div>
	<div id="ttbot"> </div>
</div>

The first function we will name ‘show’ and it will be accessible by calling tooltip.show(). It will need to take two parameters… the content string and an optional width integer. To begin, it will need to check and see if the tooltip has been added to the DOM yet. If it does not exist the divs need to be built and added to the body. Either way the innerHTML of the contentdiv will need to be set to the content parameter, the height and width set and the fade function set to a timer.

show:function(v,w){
if(tt == null){
 tt  = document.createElement('div');
 tt.setAttribute('id',id);
 t  = document.createElement('div');
 t.setAttribute('id',id  + 'top');
 c  = document.createElement('div');
 c.setAttribute('id',id  + 'cont');
 b  = document.createElement('div');
 b.setAttribute('id',id  + 'bot');
 tt.appendChild(t);
 tt.appendChild(c);
 tt.appendChild(b);
 document.body.appendChild(tt);
 tt.style.opacity  = 0;
 tt.style.filter  = 'alpha(opacity=0)';
 document.onmousemove  = this.pos;
}
tt.style.display  = 'block';
c.innerHTML =  v;
tt.style.width  = w ? w + 'px' : 'auto';

if(!w  && ie){
 t.style.display  = 'none';
 b.style.display  = 'none';
 tt.style.width  = tt.offsetWidth;
 t.style.display  = 'block';
 b.style.display  = 'block';
}

if(tt.offsetWidth  > maxw){tt.style.width = maxw + 'px'}

h =  parseInt(tt.offsetHeight) + top;
clearInterval(tt.timer);
tt.timer =  setInterval(function(){tooltip.fade(1)},timer);
},

The next function we need is the position function that will set the top and left values of the tooltip as the cursor moves. First we calculate the position based on the browser and then we set the values taking into consideration the global offset variables.

pos:function(e){
 var u = ie ? event.clientY + document.documentElement.scrollTop : e.pageY;
 var l = ie ? event.clientX + document.documentElement.scrollLeft : e.pageX;
 tt.style.top = (u - height) + 'px';
 tt.style.left = (l + left) + 'px';
}, 

Next we need to create a function that will fade the tooltip from its current opacity to the target opacity based on the direction variable that is passed to it.

fade:function(d){
 var a = alpha;
 if((a !=  endalpha && d == 1) || (a != 0 && d == -1)){
   var  i = speed;
   if(endalpha  - a < speed && d == 1){
      i  = endalpha - a;
   } else  if(alpha < speed && d == -1){
      i  = a;
  }
  alpha  = a + (i * d);
  tt.style.opacity  = alpha * .01;
  tt.style.filter  = 'alpha(opacity=' + alpha + ')';
   }else{
     clearInterval(tt.timer);
     if(d  == -1){
     tt.style.display  = 'none';
  }
 }
},

Finally the function to hide the tooltip onmouseout.

hide:function(){
	clearInterval(tt.timer);
	tt.timer = setInterval(function(){tooltip.fade(-1)},timer);
}

That completes the JavaScript. We are left with a 2kb script that is compatible with IE6, IE7, Firefox, Opera and Safari.

Here is the full script

var tooltip=function(){
 var id = 'tt';
 var top = 3;
 var left = 3;
 var maxw = 300;
 var speed = 10;
 var timer = 20;
 var endalpha = 95;
 var alpha = 0;
 var tt,t,c,b,h;
 var ie = document.all ? true : false;
 return{
  show:function(v,w){
   if(tt == null){
    tt = document.createElement('div');
    tt.setAttribute('id',id);
    t = document.createElement('div');
    t.setAttribute('id',id + 'top');
    c = document.createElement('div');
    c.setAttribute('id',id + 'cont');
    b = document.createElement('div');
    b.setAttribute('id',id + 'bot');
    tt.appendChild(t);
    tt.appendChild(c);
    tt.appendChild(b);
    document.body.appendChild(tt);
    tt.style.opacity = 0;
    tt.style.filter = 'alpha(opacity=0)';
    document.onmousemove = this.pos;
   }
   tt.style.display = 'block';
   c.innerHTML = v;
   tt.style.width = w ? w + 'px' : 'auto';
   if(!w && ie){
    t.style.display = 'none';
    b.style.display = 'none';
    tt.style.width = tt.offsetWidth;
    t.style.display = 'block';
    b.style.display = 'block';
   }
  if(tt.offsetWidth > maxw){tt.style.width = maxw + 'px'}
  h = parseInt(tt.offsetHeight) + top;
  clearInterval(tt.timer);
  tt.timer = setInterval(function(){tooltip.fade(1)},timer);
  },
  pos:function(e){
   var u = ie ? event.clientY + document.documentElement.scrollTop : e.pageY;
   var l = ie ? event.clientX + document.documentElement.scrollLeft : e.pageX;
   tt.style.top = (u - h) + 'px';
   tt.style.left = (l + left) + 'px';
  },
  fade:function(d){
   var a = alpha;
   if((a != endalpha && d == 1) || (a != 0 && d == -1)){
    var i = speed;
   if(endalpha - a < speed && d == 1){
    i = endalpha - a;
   }else if(alpha < speed && d == -1){
     i = a;
   }
   alpha = a + (i * d);
   tt.style.opacity = alpha * .01;
   tt.style.filter = 'alpha(opacity=' + alpha + ')';
  }else{
    clearInterval(tt.timer);
     if(d == -1){tt.style.display = 'none'}
  }
 },
 hide:function(){
  clearInterval(tt.timer);
   tt.timer = setInterval(function(){tooltip.fade(-1)},timer);
  }
 };
}();

Now on to the CSS for the tooltip which is completely customizable to match any interface.

#tt {
 position:absolute;
 display:block;
 background:url(images/tt_left.gif) top left no-repeat;
 }
 #tttop {
 display:block;
 height:5px;
 margin-left:5px;
 background:url(images/tt_top.gif) top right no-repeat;
 overflow:hidden;
 }
 #ttcont {
 display:block;
 padding:2px 12px 3px 7px;
 margin-left:5px;
 background:#666;
 color:#fff;
 }
#ttbot {
display:block;
height:5px; 
margin-left:5px;  
background:url(images/tt_bottom.gif) top right no-repeat; 
overflow:hidden;
}

To build and hide a tooltip call the script as below. The second parameter in the show function is optional, if not passed the width will automatically adjust to the content within the maxh limit.

onmouseover="tooltip.show('Testing  123 ', 200);"
onmouseout="tooltip.hide();"

This is great. I’d been looking for something similar. Thanks again for great posts.

Very nice, I do find myself wondering why though? Why “reinvent the wheel” when there’s already several premade libraries that do this for you. Mootools has a really nice, simple tooltip system built in to it already. All in all though… Good Job, keep up the good work.

Jacob Gube

@Sean: That’s an excellent comment, and a valid point – and one which many people are probably thinking of as well.

There are indeed a huge selection of frameworks and libraries available that does tool tips, but the key here is that it’s lightweight.

Let’s take for example, jQuery, which at its compressed state is around 30KB 16KB (for Gzip’ed + minified as of v 1.2.6). Including jQuery and a plugin (or your own script), just for tooltip functionality is quite excessive. If you’re to use jQuery for other things such as handling Ajax requests and events, creating complicated chained effects, and as the backbone of your web application’s end user interface, then the 30KB 16KB is nothing.

Additionally, though this tutorial provides a working, downloadable example of a tooltip script – it’s more a tutorial on JavaScript – to give you inspiration for your own scripts. Some of the concepts covered include working with opacity and alpha, conditionals for different web browsers, and how to write clean and logical code.

Hi Jacob! This is a great tooltip thank you for making this. I was wondering if it might be possible to add a delay for tooltips coming up?

Ed

Nice tut Jacob. Would it be possible to expand on this in a future post to describe how to make interactive tooltips (a la Netflix)?

@Mike: Thanks for the compliments, but this wonderful script was contributed by Michael Leigeber of the Leigeber Web Development Blog, so make sure to send him a shout-out.

To answer your question, you can tweak the script’s behavior by playing around with the variables such as speed, timer, alpha, etc. but to achieve your particular change, first look for the hide function, it should look like this:

 hide:function(){
  clearInterval(tt.timer);
   tt.timer = setInterval(function(){tooltip.fade(-1)},timer);
  }

in the last line: modify the timer to an integer… try something like 400, or 500. like this:

 hide:function(){
  clearInterval(tt.timer);
   tt.timer = setInterval(function(){tooltip.fade(-1)},400);
  }

once you’re satisfied, to keep your code clean, declare a variable on top, something like:

var hideDelay = 400;

and then change the value of:

tt.timer = setInterval(function(){tooltip.fade(-1)},timer);

to

tt.timer = setInterval(function(){tooltip.fade(-1)}, hideDelay);

Let me know if you encounter any trouble or need further help – feel free to shoot me an email.

@Ed: That’s a great suggestion! if I see enough requests, I may do a tutorial on a Netflix-style interactive tooltip using jQuery.

Has anyone else noticed that fox news has started to use this type of ad on their website on certain keywords. That seems so spamish on such a “mainstream” news site. Oh well, the old media is failing.

hi, i’m just wondering if your tooltip application apply the same functionality if the scroll of the screen enables.
Im trying on my application but it seems the tooltip stays in the upper portion of the screen if I scroll down.
Please Help. Need advice. Thanks.

This script is great! Like you said, there isn’t a lightweight choice if you only want a tooltip. The only question I have is how do you make t display underneath the cursor instead of above?

Stijn

July 27th, 2008

Excellent script, does exactly what it’s supposed to do. Nothing more, nothing less.

July 30th, 2008

hey Jacob, love the script and the tutorial, very elegant and performs great! I’m just starting to stumble my way into the world of JS and played around with certain variables that I thought might achieve this unseccesfully, but…

how might I got about making it so that after initially opening the tooltip would remain static in that position until the cursor moved off the object? is that possible?

thanks, and either way I love it!

kevin

July 31st, 2008

Very very nice script, thanks for the script…

couple o questions”: how come in IE it causes the windows timer-icon to flicker on and off as if it is loading something constantly as you move your mouse around the page? also is there a way to delay it one second, as in, dont have the tooltip unless some one rests their mouse over the desired text? Thanks!

Rebecca

August 4th, 2008

Looks great! Is there a way to allow users to globally turn on and off the appearance of the tooltips?

Enrico

August 6th, 2008

Very nice, but maybe I found a bug in IE6: if you scroll the page when you are on a tooltip, the box won’t scroll with the page and it’ll stay far away from the cursor. This is not the case in FF.
You can see it here

Sven

August 18th, 2008

very nice work.. but one question..

at the moment i think the “x-y 0 point” is at the bottom left..

what do i have to change to make the top left of the tooltip the 0-point?

greetings

Sven

August 18th, 2008

sorry for asking, got it on my own.. simple mathematics :D

replaced

tt.style.top = (u – h) + ‘px’;
tt.style.left = (l + left) + ‘px’;

by that

tt.style.top = (u + top) + ‘px’;
tt.style.left = (l + left) + ‘px’;

if anyone else is interested.

Jacob,

I’ve got a live example that reveals the issues in IE while scrolling. Check it out at http://www.yemkay.com/share/tooltip/out.html. The tooltip remains in the upper portion even when we scroll down or right. It works well in Firefox though.

Thanks for a light weight tooltip function.

NickWong

August 22nd, 2008

Hello All,
I fixed this for IE6, so thought I would share.

To make it work in IE6, change the pos function as follows:

pos:function(e){
// For IE6 compatibity – nick 22/08/2008 11:32
var u = 0, l = 0;
if( typeof( window.pageYOffset ) == ‘number’ ) {
//Netscape compliant
u = window.pageYOffset;
l = window.pageXOffset;
} else if( document.body && ( document.body.scrollLeft || document.body.scrollTop ) ) {
//DOM compliant
u = document.body.scrollTop;
l = document.body.scrollLeft;
} else if( document.documentElement && ( document.documentElement.scrollLeft || document.documentElement.scrollTop ) ) {
//IE6 standards compliant mode
u = document.documentElement.scrollTop;
l = document.documentElement.scrollLeft;
}

u = ie ? event.clientY + u : e.pageY;
l = ie ? event.clientX + l : e.pageX;
tt.style.top = (u – h) + ‘px’;
tt.style.left = (l + left) + ‘px’;
}

Cheers
Nick

this is very cool effect, great job.. keep up the good work!!!!

Enrico

August 28th, 2008

I’m sorry, but it seems to me that the solution proposed by NickWong doesn’t work at all.
I tried to do the change, but IE says “tooltip not defined”, and also in FF the tooltip disappears.
I noticed that there’s no comma at the end of the function(e) proposed, but adding it in unuseful.
Ah, and the scroll bug appears in IE7, too…

Enrico

August 28th, 2008

Maybe I found: simply, copying the code the apostrophe becomes high comma in ‘px’ and ‘number’.
After the substitution, everything works!

ghena

August 29th, 2008

Hi,
I’m trying to use it
and I this problem.

The tooltip goes over the right page limit not flip horizontally if the px on the right are less the “tt” width.

Someone have found and solved this bug ?

Geoff

August 29th, 2008

Jacob-

Great small script. To Mike’s request, is it possible to build in a delay so the tooltip doesn’t appear immediately. I’d like to use this on a the main nav, per my client’s request (I convinced them to abbreviate names of business units in main navigation, but promised to have full names appear in tooltip form). Thanks.

Paul

September 1st, 2008

Can you please help me on how can i insert a balloon image in the script to have a balloon tooltip that fades.

Pete

September 18th, 2008

Michael,

Thanks for this great effect. It took me 5 mins to read, install and see it work. Excellent having the demo site.

The only thing I would change is having a selector for ‘body’ in your CSS. Most sites would already have their own. So I removed this, changed the relative reference for the images and voila it all worked perfectly.

By the way I am using Firefox 3 as my target browser

Thanks again

peet…

Lance

September 30th, 2008

I have an answer and a question:

kevin asked a question at the end of July that I don’t believe was answered. The flickering is caused by the images referenced in the CSS not being present. If you remove the background statements from the CSS or add the images to your site, the flickering should go away.

Now my question:

Very nice tutorial & script. It plugged in very nicely to my application, however in my case I am trying to programmatically add the tooltip to certain images on my page via Javascript a la:

myImg.onmouseover=function() { tooltip.show(‘Solved by ‘+solver); };

where myImg is some image on my page (changes each time this line is called) and solver is a variable that I set to a potentially different value each time this code is executed (on a different image).

What I end up with is the same (last) value of solver on the tooltip for all images. I believe this is because solver is not being evaluated when I am setting the onmouseover function, but rather deferred until the mouseover actually occurs, at which time solver has taken on a new value.

I keep getting myself twisted up in knots because I can’t seem to get anything unique into that line of my code that is evaluated at that time. Any suggestions?

Thanks,
…Lance

Kostas

October 14th, 2008

Thank you for this great article and piece of code. Really simple and concise yet very good result!
A couple of suggestions:
a) place the main div at top of the page when creating it because if it is in a container with fixed size it will create a scroll bar briefly (until moved to place).
b) in slow computers (like mine) it shows in the position created before moved to place, so make it invisible until positioned.
The above can be achieved by css properties: top:0; left:0; display:none; or by code when creating it.
Thank you again for your time and effort.

I do see the need for this. I have to integrate this into the “Source” section of a CMS without stylesheet or js linking in the head. It has to happen in the content area. I’d rather use this standalone than with file import dependencies.

Thanks. Very nice looking.

Keefe

November 6th, 2008

It is nice indeed but using specific class and putting the actual javascript code (onmouseover & onmouseout) is not an ideal design. Visitors that view the website with their javascript disabled will not see the tooltip at all.

Damon

November 11th, 2008

Is there anyway to change this to be positioned and styled at the bottom right of the mouse?

Michael

November 20th, 2008

Very nice script. I discovered and fixed the scrolling problem before I realised there were these comments at the bottom and there was a fix already.

Anyway, there is a problem with and in IE6. IE7 and Firefox are fine. The pop-up div goes behind select dropdowns when it should be on top in IE6. Z-index does not solve the problem. I have searched the web and find iframe can be used as a fix and I am currently making the change. Has anyone done this already?

Hi Jacop, your script is very nice but have a small problem when load images and text. This is my fix:

In your css tooltip, replace:

#ttcont {
display:block;
padding:2px 12px 3px 7px;
margin-left:5px;
background:#666;
color:#fff;
}

with:

#ttcont {
float: left;
display:block;
padding:2px 12px 3px 7px;
margin-left:5px;
background:#666;
color:#fff;
}

You done! Sorry, my English is poor, but I’m thankyou very much for your nice script.

Very nice! I love the way it works! I’m just having a small issue with ie7. I’m using .png files for the images for the bubble and I can not get the images to display correctly on IE7. It is getting rid of the alpha channel and that is causing the images to look gray instead of white like they are supposed to. Any suggestions?

Thanks!

very nice script!!
one question though..

when I hover my mouse on the anchor tag I get this popup. but dont know why my cursor icon changes to ‘arrow’ icon instead of ‘hand’ icon as it is on the anchor tag.

Really enjoyed your script. I have tweaked the CSS a little to use on my own site. Like others, I just don’t want to use frameworks. I want to keep things simple and understand most of the code on my site.

I am playing around with your script and Google Maps. I don’t like their balloon style infoWindows. Here is what I am playing with: http://www.bobbystuff.com/About_Me/mapped_photos.php

I am having problems when I click twice on a camera icon so I need to tweak the script.

And now my question. In the line

pos:function(e){

how does this function get a value for ‘e’. I see that pos is called as this.pos but where does the ‘e’ parm come from?

Thanks,

Hey, nice script.
Added some delay to fade out:

Add this lines:

var delayTimer;

add the method delayHide:

delayHide: function( seconds )
{
tt.delayTimer = setInterval( function(){Tooltip.hide()}, seconds * 1000 );
}

And now we need this line in two places:
clearInterval(tt.delayTimer);

Copy it under the following line in the methods hide and show:
clearInterval(tt.timer);

And now in the HTML-Element do: onmouseout=”Tooltip.delayHide(.5);”

hello this is very helpful, big props to the developer who shared this with us. I noticed you can use BR and EM, but any attempt to put a link in the tooltip seems to break it, is there any way to insert a link into the tooltip??

Fully working with IE6 IE7 Firefox Opera Google Chrome and Opera. I’ve tested it. Probably omkar and greatonkar u got not latest update. Ok here is the link to the three files u might download it saperately and test it on your localhost.

http://sandbox.leigeber.com/tooltip/ —->view source save as index.php or default.asp or index.html any kind u like.

http://sandbox.leigeber.com/tooltip/script.js —-> save it as script.js

http://sandbox.leigeber.com/tooltip/style.css —-> save it as style.css

put all these 3 files in one directory as well the images folder which you had downloaded earlier. Hopes this helps.

Thank to the Author Michael Leigeber Keep up with good works. Thank Bro.

May i ask. Michael Leigeber why don’t you put credit in the script or copyright it. This content is valueble yo.

Hello there, the code is just great. However I have a small problem. When the stung shown in the tooltip has ” or ‘ in it, the script fails. How do I prevent this. I can not comment the ‘ or ‘ as they are already commented in the php var i have, and the output is:

onmouseover=”tooltip.show(”, 200);”

I mean
[code]onmouseover=”tooltip.show('$var', 200);[/code]

Hello,

This is probably a really easy fix but can anyone tell me how to center the tooltip above the cursor instead of aligning it to the left edge? I’d really appreciate it! Thanks in advance.

ruudvan

June 20th, 2009

hello…thanx for a really nice script.

There is a small issue that probably needs to be seen. When the text is near the corner boundary of the window or near some side boundary, the popup gets hidden behind the window boundary. Is there some way to make it change sides when near the window boundary. (like if it pops out of cursor’s left side when text is near windows right boundary and thus not get hidden by the boundary)

Chris

June 20th, 2009

I’ve spent some time trying to figure out how to get the tooltip to display centered above the text (So the center of the tooltip is directly over the mouse).

So if anyone wants to know how it’s done, here is what you have to do:

1. Change “var left = 3;” to “var left = 0;”

2. Change “tt.style.width = w ? w + ‘px’ : ‘auto’;” to “tt.style.width = ’200px’;” // Unfortunatly it doesn’t seem possible without having a fixed width.

3. Change “tt.style.left = (l – left) + ‘px’;” to “tt.style.left = ((l – left) – 100) + ‘px’;”

I realise these aren’t the worlds best instructions so I do apologize, however that should fix it.

*You could probablly get the tooltip to center its self above the mouse with a dynamic width; but I havn’t figured that out yet*

Hope that helps,

~ Chris

Hi, i tried customizing your code and implementing it in a form. This is the scenario in IE…

I have my form with few text fields, select boxes and other form elements. For the validation part, i tried highlighting the form elements with a red border around and applying the tooltip to show the error messages on mouseover of the same. When i do mouseover on the select box in an error state, it overlaps the tooltip sending it backwards. On mouseover, I tried appending the IFRAME dynamically in this case but not getting the desired output. It would be really appreciated, if you can help me out in this matter.

Thanks!

I resolved the tt.timer issue. All the files had to be in the same folder.

I am now having an issue with a large space being created before my text after I hover over something.

I would also like to find a way to move the tooltip so that it is evenly spaced (top to bottom) from where you hover instead of it being even with the bottom.

Thanks!

Just to share a quick and easy way to pass quoted strings in the function call is with…

How do you detect the edge of the window to keep the tooltip within the window or display the tooltip to the left if the edge of the window is on the right?

Mark

November 9th, 2009

I’m interested in coloring the text inside the tooltip — many different lines of text in one tooltip with varying colors. I can use simple tags to make the text bold or strong, as in your examples, but whenever I try to use in-line styles or anything else with an attribute (even if I make sure to use \’ instead of “) I always run into problems.

Thanks.

Mark

November 10th, 2009

Sorry to double-post, but I figured out what I was doing incorrectly.

I’m writing a PHP program and was writing HTML within PHP echo statements. Due to the fact that the show function within the script is coded in Javascript, you have to “escape” any apostrophes that you use when you’re passing in an HTML formatting tag with an attribute (you can see this in the example page where an image is used in the tooltip). The syntax for that is \’ as opposed to simply ‘.

I couldn’t figure out why my code wasn’t working because I -was- using the escaping properly. My issue was that PHP -also- requires escaping because its echo strings are delineated by apostrophes as well. So when the Javascript read my HTML and say there was a line of code in there:

Hello;

the Javascript would take care of the escaping when it returned that line, leaving only the apostrophes without the forward slashes. However, I wanted those forward slashes to remain for PHP because I have to use escaping there as well. So, in effect, I had to double escape those characters:

Hello;

One forward slash for the first forward slash, and another for the apostrophe. When the Javascript interprets the \\\’ it leaves only \’ which is what I needed for the PHP.

Very confusing but it makes sense now and works like a charm.

I’m having an issue with the toolTip not showing in IE but it works fine in FF and Safari.

The issue is specific to my text with the tooltip being dynamically generated. I have a javascript file that parses through google calendar and creates the html.

For some reason, IE can’t add the tt div info to this dynamically generated html.

I believe that the JS code is not able to perform this function in IE on my dynamically generated code:

show:function(v,w){
if(tt == null){

Any ideas on how to fix this?

Otherwise everything works great.

(BTW – it’s supposed to show on the title of the Upcoming Events section in the lower left hand corner of the page).

For those looking for an Internet Explorer fix, I have came up with one. I’ve tested it on several resolutions, etc and it seems to work okay. I used IE8 to perform the test.

It’s quite simple, in script.js find:

tt.style.top = (u – h) + ‘px’;

and replace this with:

if (/MSIE (\d+\.\d+);/.test(navigator.userAgent)){
tt.style.top = ((u – h)+100) + ‘px’;
} else {
tt.style.top = (u – h) + ‘px’;
}

Hopefully this’ll work for you guys :)
Also, to the author: amazing script, thanks!

Jack Penny

June 6th, 2010

Update: turns out my original fix was way off, I was looking at the wrong aspect.

Anyway, to fix it properly (fixed scrolling etc in IE) I gave the body tag an ID (e.g. ) then changed
document.documentElement.scrollTop to document.getElementById(“bodyId”).scrollTop

Steve

June 10th, 2010

Would it be possible for someone to explain how to add a delay before the tooltip appears? The solution posted earlier does not work, and merely slows down the fade out. Thanks!

I’m working with ‘em’s; When using ctrl-Mousewheel to change the size, the tooltip’s position doesn’t move proportionally to the change made, moving further away as more as I increase the size.
This happens only in IE (IE8), but works correctly with FF.

Any ideas how to prevent this ?

otherwise : Bravissimo!!!

June 29th, 2010

This is a great script, but I was wondering how do I trim it down further? I don’t need the graphics or their css references so I was able to clear out some code by ditching those. I can achieve the same effect using css3 in just the #tt style (I only lose the rounded corners in IE, since IE doesn’t yet support css3).

However, I don’t know JavaScript well enough to comfortably edit “script.js” to remove all references to the #tttop, #ttcont, & #ttbot styles. It would be great if someone was willing to post a clean, stripped down version of the code with the assumption that no graphics and only css3 is to be used.

Thanks!

If you scroll up and click on the link where it says “View the JavaScript Tooltip demonstration.” and then right-click on the page and click “View Source”, your browser will show you the source code for the page and how it all works together. Take particular note that the style sheet code is being linked to in a separate file in the same directory. It is called “styles.css” and linked with the code:

Chris, all you have to do is on you pages use the mouseover and mouseout. You dont need to have the text, you can even do it on pictures just be sure to include mouseover and mouseout. Example and make sure that you are linking the script to your site.

tt.style.top = 3 + 'px';
}else{
tt.style.top = (u – h) + 'px';
}

if(screen.width – l <= 300){

Thanks for great script, even more for sharing it. I have tweaked it to delay showing the Tootip and automatically hide it after predetermined time.

1. Add variables after existing
var showDelay=1000;// show after delay of 1 second
var showFor=3000; // show for 3 seconds
2 Add pausecomp function after hide
pausecomp :function(millis){

/* Thanks Curtesy Sean McManus http://www.sean.co.uk/a/webdesign/javascriptdelay.shtm*/
var date = new Date();
var curDate = null;

do { curDate = new Date(); }
while(curDate-date < millis);
}
3. Add showdelay function
showdelay: function(v,w,t){
showFor= t ? t:showDelay;
this.pausecomp(showDelay);
this.show(v,w);
setTimeout ( "tooltip.hide();", showFor );},
4. Use onmouseover="tooltip.showdelay("Testing Delayed Dispaly",200,5000);. This will delay the tooltip for one second and hide it after 5 seconds.

Hi !

I had the scrolling issue on IE8 as well. I used Jack Penny’s fix but I can’t modify the body but you can get it using getElementsByTagName()

pos:function(e){
var body = document.getElementsByTagName(‘body’)[0];
var u = ie ? event.clientY + body.scrollTop : e.pageY;
var l = ie ? event.clientX + body.scrollLeft : e.pageX;

Hi.

First of all great script love it. Easy and very practical script.

Though i want to make a little change but cant get it right.
I want to keep the original dark grey balloon pop-up. Next to it i want the same balloon but in a different color, yellow.

Maybe i can explain it better this way.
Hover item 1 = Balloon grey: when i hover over this item the balloon should be with a grey background.

Hover item 2 = Balloon yellow: when i hover over this item the balloon should be with a yellow background.

I tried copy-ing the tooltip function and changing the id’s used in CSS. I do get to different balloons but the new copied function yellow balloon sticks to a static position.

Can someone understand this problem and know how to fix it?
Please help me out.

Brendan

August 1st, 2011

I created a small fix for the tooltip hiding behind my gridview control.
In the Show function comment out the document body
and put in the two lines for t1 variable.
Adjust GridView2 name below to id of your control

var t1 = document.getElementById(“”)
t1.appendChild(tt);
// document.body.appendChild(tt);

Have Fun

Hi there,
I am without exception working with images on my site ( I am an artist) so I wonder if it is possible to trigger the tooltip from an image instead from a text?
Eagerly looking forward to an answer

Yes, just use the class object on the image instead of text span/div or link.

Go to http://www.britain2spain.co.uk/default.asp?PID=3&PropID=850 and hover over the icons above the photograp block – I have set mouse pointer to look as if it is a link [style="cursor:pointer;"]. Same for currency flags to the right of price.

I still have an issue with placement in IE, but in FFox and Chrome it is beautiful!

If you get stuck, give me a ‘shout’

hi, thanks for this… very simple to implement…

in case anyone’s wondering, you can update this dynamically using asp.net with this code:

Label1.Attributes.Add(“span class”, “hotspot”)
Label1.Attributes.Add(“onmouseover”, “tooltip.show(‘” & TextBox1.Text & “” & TextBox2.Text & “‘);”)
Label1.Attributes.Add(“onmouseout”, “tooltip.hide();”)

the only problem is if it’s too many character the script fails…. don’t know why… any ideas???

great script anyway…. thanks

hi, just to follow up on my last comment… it’s not too many characters, it’s if there’s an astrophe in the paragraph, it breaks the javascript code…. any ideas? thanks

Yes, put a \ before the apostrophe … eg:

Hi,
A great effort. Has anyone extended this to become a sticky note with a clickable hyperlink in it?
Thanks,

This is great, thanks, especially the namespace stuff – hadn’t seen that before in JS, great encapsulation.

How to incorporate tooltip/onmouseover the drawChart function

var s= parseInt();

google.load(‘visualization’, ’1′, {packages:['gauge']});
google.setOnLoadCallback(drawChart);
function drawChart() {

var data = new google.visualization.DataTable();
data.addColumn(‘string’, ‘Label’);
data.addColumn(‘number’, ‘Value’);
data.addRows(4);
data.setValue(0, 0, ‘DAY’);
data.setValue(0, 1, 5);
var chart = new google.visualization.Gauge(document.getElementById(‘chart_div’));
var options = {width:400, height: 120,minorTicks: 5};
chart.draw(data, options);

Hi,

Is it possible to position this tooltip below the link? If so, how?
Also, I’d like it to display on the left side instead of right. How to accomplish this?

Just used the the tool tip on my website. Exactly what I was after, a simple implementation that does not conflict with other stuff (like jQuery).

Hi, thanks so much for the tutorial, looks really nice. I made some changes and want to use it within our company’s software, but I wonder about the license. Is it public domain?
Thanks

Thanks for this. This JavaScript only solution is exactly what I’ve been looking for. It has yet to break for me even on very old browsers. I recommend this over jQuery alternatives which may cause conflicts.

Your code is nice but I doubt that it is useful for multiple pages because we would have to copy the static code to every page, unless you meant to provide this code as a reference for further expansion.

Hi,
Just wanted to say a huge BIG thank-you to all you guys who have contributed. This script and its mods are simply fantastic and just what I’ve been searching for.
Thanks
