本文实例讲述了jQuery使用getJSON方法获取json数据。分享给大家供大家参考,具体如下:

demo.js:


?


[
   {
     "name" : "吴者然" ,
     "sex" : "男" ,
     "email" : "demo1@123.com"
   },
   {
     "name" : "吴中者" ,
     "sex" : "男" ,
     "email" : "demo2@123.com"
   },
   {
     "name" : "何开" ,
     "sex" : "女" ,
     "email" : "demo3@123.com"
   }
]


demo.html:

<html>
<head>
<meta http-equiv= "Content-Type" content= "text/html; charset=utf-8" />
<title>getJSON获取数据</title>
<script type= "text/javascript" src= "js/jquery-1.10.1.min.js" ></script>
<style type= "text/css" >
#divframe {
   border: 1px solid #999;
   width: 500px;
   margin: 0 auto;
}
.loadTitle {
   background: #CCC;
   height: 30px;
}
</style>
<script type= "text/javascript" >
$( function (){
   $( "#btn" ).click( function (){
     $.getJSON( "js/demo.js" , function (data){
       var $jsontip = $( "#jsonTip" );
       var strHtml = "123" ; //存储数据的变量
       $jsontip.empty(); //清空内容
       $.each(data, function (infoIndex,info){
         strHtml += "姓名:" +info[ "name" ]+ "<br>" ;
         strHtml += "性别:" +info[ "sex" ]+ "<br>" ;
         strHtml += "邮箱:" +info[ "email" ]+ "<br>" ;
         strHtml += "<hr>"
       })
       $jsontip.html(strHtml); //显示处理后的数据
     })
   })
})
</script>
</head>
<body>
<div id= "divframe" >
   <div class= "loadTitle" >
     <input type= "button" value= "获取数据" id= "btn" />
   </div>
   <div id= "jsonTip" > </div>
</div>
</body>
</html>


效果图如下:

这里把 JSON 的后缀名改为 JS,放在 WEB 容器中则可以正常读取。
