struts2.1+json+jquery1.4实现用户名校验
?strutsaction代码这样写的 其实很简单
package com.vo;
import com.opensymphony.xwork2.ActionSupport;
public class HelloWorld extends ActionSupport {
private static final long serialVersionUID = 1035615877474749202L;
private String name;
private String result;
private String pass;
// ajax请求参数赋值
public void setName(String name) {
this.name = name;
}
public void setPass(String pass){
this.pass = pass;
}
// ajax返回结果
public String getResult() {
return result;
}
@Override
public String execute() {
this.result = name+pass;
System.out.println(pass);
return SUCCESS;
}
}
?然后配置struts.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="ajax" extends="json-default"> <action name="hello" class="com.vo.HelloWorld"> <result type="json" /> </action> </package> </struts>
?
最后写jsp文件
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
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>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</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="jquery/jquery-1.4.min.js"></script>
<script type="text/javascript">
function clickButton()
{
//alert($('#name').val());
var url = "hello";
var params = {
name:$("#name").val(),
pass:$("#pass").val()
};
jQuery.post(url, params, callbackFun, 'json');
}
function callbackFun(data)
{
alert(data.result);//对应HelloWorld类的message属性
document.getElementById("jieguo").innerHTML=data.result;
//获取数据后渲染页面
}
</script>
</head>
<body>
帐号:<input id="name" type="text">
密码:<input id = "pass" type="text">
结果:<span id="jieguo"></span>
<input type="button" value="ok" onclick="javascript:clickButton();">
</body>
</html>
?
里边其实还有jquery带代码中自己下载吧
我用的工具是myeclipse8.6forspring 布局如下图
