 js处理

<script type="text/javascript">
$(document).ready(function(){
    $(".helps dd:first").find("em").stop('true','true').animate({opacity: "show", top: "-150"}, "slow");
	$(".helps dd").hover(function() {
		$(this).find("em").stop('true','true').animate({opacity: "show", top: "-150"}, "slow");
	}, function() {
		$(this).find("em").stop('true','true').animate({opacity: "hide", top: "-85"}, "fast");
	});
});

</script>
