简单示例代码:
<body>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$(document).bind("click",function(e){
var target = $(e.target);
if(target.closest(".pop").length == 0){
$(".pop").hide();
}
})
})
</script>
<div class="pop"></div>
点击空白的地方指定div 隐藏消失了
</body>
</html>
