It's always a joy to understand how things work. Well, at least I do. Alright, this time, I want to share with you all, how to create a simple jQuery tooltip. In this website, I'm using a script I grabed it online, and it uses onmouseover and onmouseout. It's really messy and annoying me. So, it's jQuery comes to rescue. The way it works is fairly simple, I use the Anchor tag REL and TITLE attributes to identify a tooltip and its content.

By the way, if you are having problems looking for a good iPage Web Host, you can use this website to guide you: Web Hosting Review

Getting the mouse X and Y axis

First of all, I did a search with google, and I found this little script from this blog, very useful information. It shows me the idea how to retrieve the X and Y Axis coordinate.

$(document).ready(function()
 {
  $().mousemove(function(e)
   {
    $('p').html("X Axis : " + e.pageX + " | Y Axis " + e.pageY);
  });
});

 

Detect the Anchor element

I wrote a simple selector to select only Anchor tag with REL set to tooltip, I'm using the same approach in the Navigation List menu + jQuery Animate Effect tutorial. It's very straight forward and easy.

	$('a[rel=tooltip]').mouseover(function() {
		......
	});
As a result, anchor tags that support this simple jQuery tooltip should look like this
	<a rel="tooltip" title="Testing of tooltip">sentences</a>

 

Trick to hide the TITLE Attribute's Tooltip in browser

Okay, there is one major issue we need to sort it out - The native tooltip in Mozilla browsers. If you're using TITLE attribute in Anchor tag, on mouse over, a small yellow tooltip will appear, we want to avoid that. So, a simple solution, on mouse over, we will grab the value in the TITLE attribute, then, remove its value. While on mouse out, we'll put it back on. : ) simple and easy. You'll able to see this in the final code.

 

 

CSS

Finally, the CSS. I try to make the tooltip easy to reskin, you can customize the tooltip in this section. The structure of tooltip it made up with 3 sections - header, body and footer. It will be very easy for you to create your own skin.

#tooltip {
	position:absolute;
	z-index:9999;
	color:#fff;
	font-size:10px;
	width:180px;	
}

#tooltip .tipHeader {
	height:8px;
	background:url(images/tipHeader.gif) no-repeat;
}

/* IE hack */
*html #tooltip .tipHeader {margin-bottom:-6px;}

#tooltip .tipBody {
	background-color:#000;
	padding:5px 5px 5px 15px;
}

#tooltip .tipFooter {
	height:8px;
	background:url(images/tipFooter.gif) no-repeat;
}

	}).mouseout(function() {

</style>

<body>

<div id="paragraph">
A paragraph typically consists of a unifying main point, thought, or idea accompanied by supporting details. The non-fiction paragraph usually begins with the general and moves towards the more specific so as to advance an argument or point of view. Each <a rel="tooltip" title="A paragraph typically consists of a unifying main point, thought, or idea accompanied by <b>supporting details</b>">paragraph</a> builds on what came before and lays the ground for what comes next. Paragraphs generally range three to seven sentences all combined in a single paragraphed statement. In prose fiction successive details, for example; but it is just as common for the point of a prose paragraph to occur in the middle or the end. A paragraph can be as short as one word or run the length of multiple pages, and may consist of one or many <a rel="tooltip" title="Testing of Sentences">sentences</a>. When dialogue is being quoted in fiction, a new paragraph is used each time the person being quoted changed.
