jquery如何实现点击空白处隐藏元素(2)

在给大家分享一下js实现的点击div区域外隐藏div区域的方法代码:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="text/javascript" src="js/jquery-1.4.4.min.js" ></script>
<title></title>
</head>
<style type="text/css">
body
{
background-color:#999999;
} 
#myDiv
{
background-color:#FFFFFF;
width:250px;
height:250px;
display:none;
      }
  </style>
<body>
<input id="btn" type="button" value="显示DIV" />
 
<div id="myDiv">
This is a div;
</div> 
</body> 
<script type="text/javascript">
    var myDiv = $("#myDiv");
$(function ()
{
$("#btn").click(function (event) 
{
showDiv();//调用显示DIV方法
$(document).one("click", function () 
{//对document绑定一个影藏Div方法
$(myDiv).hide();
}); 
event.stopPropagation();//阻止事件向上冒泡
});
$(myDiv).click(function (event) 
{
event.stopPropagation();//阻止事件向上冒泡
});
});
    function showDiv() 
{
$(myDiv).fadeIn();
}
</script>
