标准jquery ajax ,接收json数据
content.jsp.
<%
String mname=(String)request.getParameter("name");
out.println("{\"comments\":[{\"name\":\""+mname+"\",\"id\":1,\"nickname\":\"King\"},{\"name\":\"Ben\",\"id\":2,\"nickname\":\"Bow\"}]}");
%>这里转义号和mname之间格式要注意，mname如果是字符串，那一定两边要加双引号。否则json不能解析。
test.jsp
<html>
<head>
<script type="text/javascript" language="JavaScript" src="/JFP/js/jquery/jquery-1.5.1.js"></script>
</head>
<body>
<table>
<tr>
<td id="Load">Button</td>
<td><input value="" size="100" /></td>
</tr>
</table>
<script>
$("#Load").click(function(){
var postData ='name=Tian Cai';
$.ajax({
url:"https://localhost:9444/HKGCB/content.jsp",
type:"POST",
data:postData,
dataType:"json",
success:function(respon){
$.each(respon.comments, function(index,item){
alert(item.name);
});
},
error:function(er){
alert(er);
}
});
});
</script>
</body>
