如果返回的json是一个list集合,则需要在js中编写循环语句输出,代码如下
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>异步接收集合数据</title>
<script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
$(function(){
$("#btn").click(function(){
$.getJSON("ajax.do",function(json){
$(json).each(function(index,user){
$("#xianshi").append("<br>"+user.uname+","+user.psw);
})
})
})
})
</script>
</head>
<body>
<button id="btn">点击异步</button>
<div id="xianshi">
