1. 服务端先返回页面基本结构（如message.jsp），

<%@ page language="java" contentType="text/html; charset=utf-8"
        pageEncoding="utf-8"%>
    <%@ taglib prefix="c"  uri="http://java.sun.com/jsp/jstl/core" %>
    <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
    <%
        String path = request.getContextPath();
        String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()
                + path + "/";
    %>
    <!DOCTYPE html>

2. example.js加载的时候，再去异步请求获取页面数据（表格、分页等），再动态创建表，分页链接等

$(function(){
        initTable();
        
        $("#searchMessage").on("click",function(){
            messageSearch(pageNo);
        });
    
    
        //获取message列表 "pageNo" : pageNo
        function initTable(){
            $.ajax({
                url : basePath + "page/message_list.action",
                type : "get",
                dataType : "json",
                success : function(dataMap){
                    createTBody(dataMap);
                    createTFoot(dataMap);
                },
                error : function(errorData){
                }
            });
        }
        //查询message
        function messageSearch(pageNo){
            var searchDateStart = $("#searchDateStart").val();
            var searchDateEnd = $("#searchDateEnd").val();
            var startDate = new Date(searchDateStart);
            var endDate = new Date(searchDateEnd);
            var num = endDate - startDate;
            if(num<0){
                $("#searchDateEnd").val('');
                swal({
                    title: "结束日期不能晚于开始日期",
                    text: "",
                    type: "error"
                });
                return false;
            }
            var receiver = $("#receiver").val();
            $.ajax({
                url : basePath + "page/message_search.action",
                type : "POST",

注意： 表格是动态创建的，其中的按钮绑定事件时，一定要先找到它的父节点（或祖先节点），再到指定节点，绑定事件

3.项目采用struts2， 返回json, 在struts中配置， 并在action中使用map来封装数据， 并添加get方法

struts.xml

<package name="message" namespace="/" extends="struts-default, json-default">
            <action name="message_*" class="messageAction" method="{1}">
                <result name="index">/WEB-INF/jsp/message.jsp</result>
                <result name="success"  type="json">
                    <param name="root">dataMap</param>
                </result>
            </action>
        </package>

action

package com.cdv.mediastar.action;
    
    import java.io.IOException;
