摘要: 这篇文章主要为大家详细介绍了ajax跨页面提交表单的相关资料,具有一定的参考价值，感兴趣的小伙伴们可以参考一下

前面提到过重复提交表单问题，处理token口令校验、重定向之外，还有一种经常使用到的方法就是新页面处理表单提交，完成后关闭当前页面，并刷新之前发送请求的页面。
这里使用了artDialog.js

1、文件结构

2、user.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 
<%@ taglib uri="/struts-tags" prefix="s"%> 
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
 <head> 
 <title>user列表</title> 
  
 <meta http-equiv="pragma" content="no-cache"> 
 <meta http-equiv="cache-control" content="no-cache"> 
 <meta http-equiv="expires" content="0"> 
 <script type="text/javascript" src="/MySSH2/jquery-1.7.js"></script> 
 <script type="text/javascript" src="/MySSH2/artDialog.js?skin=default"></script> 
 <script type="text/javascript"> 
 function openA(){ 
 window.open("/MySSH2/user/manage_addUI"); 
 } 
 </script> 
 </head> 
 <body> 
 <br/> 
 <a href="<s:url action="manage_addUI" namespace="/user"/>">添加用户</a> 
 <a href="javascript:void(0)" onclick="openA()">添加用户</a> 
  <br/> 
  用户列表：<br/> 
 <s:iterator value="#request.users"> 
 id:<s:property value="id"/><br/> 
 name:<s:property value="name"/><br/> 
 </s:iterator> 
  
 
 </body> 
</html>

3、userAdd.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 
<%@ taglib uri="/struts-tags" prefix="s"%> 
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
 <head> 
 <title>用户添加</title> 
  
 <meta http-equiv="pragma" content="no-cache"> 
 <meta http-equiv="cache-control" content="no-cache"> 
 <meta http-equiv="expires" content="0"> 
 <script type="text/javascript" src="/MySSH2/jquery-1.7.js"></script> 
 <script type="text/javascript"> 
 function AddUser(){ 
 var submitData = $('#userForm').serialize(); 
 console.log(submitData); 
 $.ajax({ 
    type : "post", 
    url : "/MySSH2/user/manage_add", 
    cache : false, 
    data: submitData, 
    dataType : 'json', 
    success : function(result) { 
    <span style="white-space:pre">  </span>if(result.success){ 
       window.opener.art.dialog({time:2,content:'保存成功'}); 
       setTimeout(function(){window.opener.location.reload();},3); 
      } 
      else{ 
      <span style="white-space:pre"> </span> window.opener.art.dialog({time:2,content:'保存失败'}); 
        setTimeout(function(){window.opener.location.reload();},3); 
       } 
       window.close(); 
      }, 
    error : function(XMLHttpRequest, textStatus, 
      errorThrown) { 
        alert("error"); 
      } 
    }); 
 } 
 </script> 
 </head> 
 
 <body> 
 <s:form id="userForm" action="manage_add" namespace="/user" method="post"> 
  用户名:<s:textfield name="user.name"/><br/><s:token></s:token> 
  <input type="button" value="保存" onclick="AddUser()"/> 
 </s:form> 
 </body> 
</html>

4、UserManageAction.java

package com.myssh2.action; 
 
import java.io.IOException; 
import java.io.PrintWriter; 
 
import javax.annotation.Resource; 
import javax.servlet.ServletException; 
 
import org.apache.struts2.ServletActionContext; 
import org.springframework.context.annotation.Scope; 
import org.springframework.stereotype.Controller; 
 
import com.myssh2.bean.User; 
import com.myssh2.service.UserService; 
import com.opensymphony.xwork2.ActionContext; 
import com.opensymphony.xwork2.ActionSupport; 
 
 
@Controller @Scope("prototype") 
public class UserManageAction extends ActionSupport{ 
 @Resource UserService userService; 
 private User user; 
  
 public User getUser() { 
  return user; 
 } 
 
 public void setUser(User user) { 
  this.user = user; 
 } 
 
 public String addUI(){ 
  return "add"; 
 } 
  
 public void add() throws ServletException, IOException{ 
  
  ServletActionContext.getResponse().setContentType("text/html;charset=utf-8");  
  PrintWriter out = ServletActionContext.getResponse().getWriter(); 
  try { 
   userService.addUser(user); 
   ActionContext.getContext().put("message", "保存成功"); 
   out.write("{\"success\":true}"); 
  } catch (Exception e) { 
    e.printStackTrace(); 
    out.write("{\"success\":false,\"msg\":\"error\"}"); 
  } 
 } 
}

页面效果

提交表单时使用$('#userForm').serialize();序列化表单数据
window.opener.art.dialog({time:2,content:'保存成功'});则是返回使用window.open的页面(或者理解为父页面)，并调用artDialog插件的定时关闭dialog
setTimeout(function(){window.opener.location.reload();},3);使用定时器刷新使用window.open的页面(或者理解为父页面)，dialog和reload的时间设置问题需重新调整。
