---------------------------test.js-------------------------------

$(document).ready(function(){
$("#userBtt").click(function(){
var username = $("#username").val();
if(username=="")
{
alert("不能为空");
}
else
{
$.post("http://localhost:8010/jqueryTest/test/test?username="+encodeURI(encodeURI(username)));
}
});
});

---------------------------TestAction.java-------------------------------

package com.javabiz.cn;

import java.io.UnsupportedEncodingException;

public class TestAction extends ActionSupport
{
private String username;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String test()
{
try {
String username2 = URLDecoder.decode(username, "UTF-8");
System.out.println(username2);
}

  catch (UnsupportedEncodingException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
    }
   return "success";

}
}
---------------------------index.jsp-------------------------------

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

现在控制台也能打印文本框里输入的值，但是就是不执行跳转,这是为什么啊？如果想跳转的话，应该怎么办？

$.post 是ajax提交
你想页面跳转使用
window.location.href=path
