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,具有一定的参考和学习ajax的价值，对ajax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。
