Old rule, post the code first
<script>
$(function(){
window.onload = function()
{
var $li = $('.taocan-title li');
var $ul = $('.taocan-content .con110');
$li.mouseover(function(){
var $this = $(this);
var $t = $this.index();
$li.removeClass();
$this.addClass('active');
$ul.css('display','none');
$ul.eq($t).css('display','block');
})
}
});
</script>
