Using the jQuery Tooltip Plug-in`s bodyHandler Argument
In this fifth installment of a seven-part series on the jQuery Tooltip plug-in, I discuss the use of the “bodyHandler” argument. It can be really useful for injecting HTML code into tooltips, thus altering their default visual appearance and behavior.
Using the jQuery Tooltip Plug-in`s bodyHandler Argument - Displaying the markup contained in web page links (Page 4 of 4 )
By means of the "bodyHandler" parameter, it is possible to perform all sorts of clever tasks with tooltips, since as you saw before, it accepts a callback function as an entrant parameter. Based on this functionality, below I coded a final example. It shows how to build tooltips that have the ability to display their own text. Take a look at the following code sample to find out how this is accomplished:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
// assign tooltip to links after web page has been loaded
// delay tooltip display 400 ms, using bodyHandler option
$(document).ready(function(){
$("a").tooltip({
delay: 0,
track: true,
bodyHandler: function() {
return $(this).html();
}
});
});
</script>
</head>
<body>
<div>
<ul>
<li><a href="http://jquery.com" title="Sample Link 1">Sample Link 1</a></li>
<li><a href="http://jquery.com" title="Sample Link 2">Sample Link 2</a></li>
<li><a href="http://jquery.com" title="Sample Link 3">Sample Link 3</a></li>
<li><a href="http://jquery.com" title="Sample Link 4">Sample Link 4</a></li>
<li><a href="http://jquery.com" title="Sample Link 5">Sample Link 5</a></li>
<li><a href="http://jquery.com" title="Sample Link 6">Sample Link 6</a></li>
</ul>
</div>
</body>
</html>
Short to code and read, isn't it? As you can see, now the callback function attached to the "bodyHandler" argument is capable of displaying the text included in each web page link. Of course, this is merely a simple demonstration of what can actually be done with this argument, so I strongly encourage you to develop your own examples and define more complex functions to be attached to this argument. It'll be an instructive experience, believe me.
Final thoughts
In this fifth installment of the series, I discussed the use of the "bodyHandler" argument, which can be really useful for injecting HTML code into tooltips, in this way completely altering its default visual appearance and behavior.
Nonetheless, as I explained before, the examples developed so far weren't suitable for use in production environments. But that is about to change. In the next part of the series I'm going to show you how to use this parameter for displaying full-size versions of a group of thumbnail images.
