jquery + struts2 + json示例
本文主要是演示一下怎么在 jquery + struts2 下使用json 来传数据，实现的效果很简单，在页面输入 “用户编号”和“用户名称” 下面用一个层来显示。
首先是regist.jsp
<%@ page contentType="text/html; charset=UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Regist.jsp</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<script type="text/javascript" src="<%=basePath %>script/jquery-1.3.2.js"></script>
<script language="javascript" type="text/javascript">
function showPersonInfo()
{
var authorid = $("#authorid").val();
var authorname=$("#authorname").val();
var url ="<%=request.getContextPath() %>/personAjaxAction.action";
$.post(url,{authorid:authorid,authorname:authorname},callback,"json");
}
function callback(data)
{
var rs = data.person
var html = "";
html+="<table><tr><td>用户编号：</td><td>"+rs.authorid+"</td></tr><tr><td>用户名称：</td> <td>"+rs.authorname+"</td></tr>";
$("#showPersonInfo").html(html);
}
</script>
</head>
<body>
<form method="post">
用户编号：<input type="text" id="authorid" name="person.authorid"/><br>
用户名称：<input type="text" id="authorname" name="person.authorname"/><br>
<input type="button" value="ajax" name="ajaxsubmit" onclick="showPersonInfo();"/>
</form>
<div id="showPersonInfo"></div>
</body>
</html>
