Easyui表单之按钮的提交

一、表单按钮的提交前代表对提交内容的验证

二、表单按钮的提交后代表对把数据提交给后台

1. 界面层页面编辑代码：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<!-- 1 JQuery的js包 -->
<script type="text/javascript" src="jquery-easyui-1.4.4/jquery.min.js"></script>

<!-- 2 css资源 -->
<link rel="stylesheet" type="text/css" href="jquery-easyui-1.4.4/themes/default/easyui.css">

<!-- 3 图标资源 -->
<link rel="stylesheet" type="text/css" href="jquery-easyui-1.4.4/themes/icon.css">

<!-- 4 easyui的js包 -->
<script type="text/javascript" src="jquery-easyui-1.4.4/jquery.easyui.min.js"></script>

<!-- 5 本地语言  -->
<script type="text/javascript" src="jquery-easyui-1.4.4/locale/easyui-lang-zh_CN.js"></script>
</head>
<body>
<script type="text/javascript">

$(function()
    {
        // 提交按钮
        $('#lb1').click(function()
        {
            $('#form1').form('submit',{
                url:'saveUserServlet',
                // 提交前验证
                onSubmit:function()
                {
                    // 检查组件验证是否通过
                    var isValid = $(this).form('validate');
                    if (!isValid){
                        $.messager.show({
                            title:'消息',
                            msg:'数据验证未通过'
                        })
                    }
                    return isValid;    // 返回false终止表单提交

                },
                // 提交后
                success:function(data)
                {
                //    alert('返回结果='+data);
                    
                    // 通过js方式解析JSON字符串
                    var msg = eval("("+ data +")");
                    
                    if(msg.success)
                    {
                        alert(msg.message);
                    }
                }
                
            });
        });
    
    
    })

</script>

2.Servlet层代码：

package com.hanqi.controller;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


public class saveUserServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
       
   
    public saveUserServlet() {
        super();
       
    }


    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        
        
            response.setCharacterEncoding("UTF-8");
            
            request.setCharacterEncoding("UTF-8");
            
            response.setContentType("text/html");
            // 处理请求
            String rtn="{'success':true,'message':'保存成功！'}";
            response.getWriter().write(rtn);
    }

    
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        
        doGet(request, response);
    }

}
