<a href="#" rel="drevil">
<span class="glyphicon glyphicon-shopping-cart"> </span> 购物车
</a>

$(function(){
$("[rel=drevil]").popover({
trigger:'manual',
placement : 'bottom', //placement of the popover. also can use top, bottom, left or right
title : '<div style="text-align:center; color:red; text-decoration:underline; font-size:14px;"> Muah ha ha</div>', //this is the top title bar of the popover. add some basic css
html: 'true', //needed to show html of course
content : '<div id="popOverBox"><img src="http://www.hd-report.com/wp-content/uploads/2008/08/mr-evil.jpg" width="251" height="201" /></div>', //this is the content of the html box. add the image here or anything you want really.
