在開發(fā)應(yīng)用中我們做了一個(gè)彈出層，有時(shí)我們會做一個(gè)關(guān)閉按鈕，這樣點(diǎn)擊關(guān)閉就可以把彈出層關(guān)閉了，但是有時(shí)希望只要不點(diǎn)擊彈出層內(nèi)就自動(dòng)關(guān)閉彈出層了，下面我總結(jié)了三個(gè)實(shí)例。
例1

復(fù)制代碼代碼如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>點(diǎn)擊空白處關(guān)閉彈出窗口</title>
<meta http-equiv="content-type" content="text/html;charset=gb2312">
<style type="text/css">
.pop{width:200px;height:130px;background:#080;}
</style>
<script type="text/javascript" src="/ajaxjs/jquery-1.6.2.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>
</head>
<body>
<div class="pop"></div>
</body>
</html>

例2,點(diǎn)擊自身以外地方關(guān)閉彈出層

復(fù)制代碼代碼如下:

<html>
<style>
.hide{display:none;}
</style>
<script type="text/javascript" src="jquery-1.6.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
    $("div.down").click(function(e) {
        e.stopPropagation();
        $("div.con").removeClass("hide");
    });
    $(document).click(function() {
        if (!$("div.con").hasClass("hide")) {
            $("div.con").addClass("hide");
        }
    });
});
</script>
<body>
    <div class="down">click</div>
    <div class="con hide">show-area</div>
</body>
</html>
 

例3

復(fù)制代碼代碼如下:
