jquery clueTip
参考 http://plugins.learningjquery.com/cluetip/
Overview
The clueTip plugin allows you to easily show a fancy tooltip when the user's mouse hovers over (or, optionally, clicks on) any element you designate in your script. If the element includes a title attribute, its text becomes the heading of the clueTip.

Quick Start Guide
Showing the most basic clueTip can be achieved in two easy steps.
1 Add HTML markup to your page for elements that you want to invoke a clueTip. By default, the clueTip plugin will use the
rel attribute to load contents into the tooltip body via AHAH.<!-- use ajax/ahah to pull content from fragment.html: -->
<p><a class="tips" href="fragment.html" rel="fragment.html">show me the cluetip!</a></p>
<!-- use title attribute for clueTip contents, but don't include anything in the clueTip's heading -->
<p><a id="houdini" href="houdini.html" title="|Houdini was an escape artist.|He was also adept at prestidigitation.">Houdini</a></p>
2 Include the jQuery core file and the clueTip plugin in the
<head> of your document. You may optionally include the hoverIntent plugin as well. After these scripts are referenced, you can reference a custom script file to invoke your clueTips (preferred) or enter the script directly in the <head> (shown below). You should also include the clueTip stylesheet (jquery.cluetip.css) after the scripts.<script src="jquery.js" type="text/javascript"></script>
<script src="jquery.hoverIntent.js" type="text/javascript"></script> <!-- optional -->
<script src="jquery.cluetip.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
$('a.tips').cluetip();
$('#houdini').cluetip({
splitTitle: '|', // use the invoking element's title attribute to populate the clueTip...
// ...and split the contents into separate divs where there is a "|"
showTitle: false // hide the clueTip's heading
});
});
</script>
<link rel="stylesheet" href="jquery.cluetip.css" type="text/css" />
You can change the default style and behavior in many ways. See API / Options for details.

}
};
- height: Setting a specific height also sets <div id="cluetip-outer"> to "overflow:auto"
- positionBy: Available options are 'auto', 'mouse', 'bottomTop', 'fixed'. Change to 'mouse' if you want to override positioning by element and position the clueTip based on where the mouse is instead. Change to 'bottomTop' if you want positioning to begin below the mouse when there is room or above if not -- rather than right or left of the elemnent and flush with element's top Change to 'fixed' if you want the clueTip to appear in exactly the same location relative to the linked element no matter where it appears on the page. Use 'fixed' at your own risk.
- topOffset:For positionBy "auto", "mouse", and "bottomTop", the number will be added to the clueTip's "top" value if the clueTip appears below the invoking element and subtracted from it if the clueTip appears above. For positionBy "fixed", the number will always be added to the "top" value, offsetting the clueTip from the top of the invoking element.
- leftOffset: For positionBy "auto", "mouse", and "bottomTop", the number will be added to clueTip's "left" value if the clueTip appears to the right of the invoking element and subtracted if the clueTip appears to the left. For positionBy "fixed", the number will always be added to the "left" value of the clueTip, offsetting it from the right side of the invoking element.
- local: for example, using the default tip attribute, "rel", you could have a link — <a href="somewhere.htm" rel=".someClass"> — that would show the contents of the first element in the DOM that has a class of "someClass."
- splitTitle: if used, the clueTip will be populated only by the title attribute
- cluetipClass: this is also used for a "directional" class on the same div, depending on where the clueTip is in relation to the invoking element. The class appears in the form of 'cluetip-' + direction +cluetipClass. this allows you to create your own clueTip theme in a separate CSS file or use one of the three pre-packaged themes: default, jtip, or rounded.
- arrows: UPDATE: this option displays a div containing an arrow background image. Arrow images are set using the background-image property in the CSS. The direction of the arrow changes depending on which side of the invoking element the clueTip appears. The arrows option sets the background-position of the cluetip div so that the arrow will accurately point to the invoking element, regardless of where it appears in relation to it.
