jsp页面 列表 展示 ajax异步实现方法

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 + "/";
%>

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",
      data : {
        "pageNo" : pageNo,
        "searchDateStart" : searchDateStart,
        "searchDateEnd" : searchDateEnd,
        "receiver" : receiver
      },
      dataType : "json",
      success : function(dataMap){
        createTBody(dataMap);
        createTFoot(dataMap);
      },
      error : function(errorData){

      }
    });
  }

  function createTBody(dataMap){
    if(dataMap!=null){
      var messageListPage = dataMap.messageListPage;
      var html = [];
      for(var i=0; i<messageListPage.length; i++){
        var message = messageListPage[i];
        var cTime = message.createtime.replace(/T/g," ");
        html.push('<tr class="gradeX center">');
        html.push('<td style="text-align:left;">'+message.content+'</td>');
        html.push('<td>' + message.provider + '</td>');
        html.push('<td>' + message.receiver + '</td>');
        html.push('<td>' + cTime + '</td>');
        html.push('<td message_id=' + message.id + '><a href="#" class="message_del btn btn-danger btn-xs"> 删除 </a></td>');
        html.push('</tr>');
      }
      $("#message_body").empty().html(html.join(''));
    }
  }

  function createTFoot(dataMap){
    if(dataMap!=null){
      startNum = dataMap.startNum;
      stopNum = dataMap.stopNum;
      totalCount = dataMap.totalCount;
      pageNo = dataMap.pageNo;
      pageSize = dataMap.pageSize;
      var str = '显示 ' + startNum + '至' + stopNum + '项 ， 共' + totalCount +' 项。';
      $("#message_showLines").html(str);
    }
  }

  $('#message_body').on('click','a.message_del',function(){
    var message_id = $(this).parent("td").attr("message_id");
    swal({
      title : "确认要删除吗?",
      text : "删除后将不能恢复!",
      type : "warning",
      showCancelButton : true,
      confirmButtonColor : "#DD6B55",
      confirmButtonText : "Yes, delete it!",
      cancelButtonText : "No, cancel plx!",
      closeOnConfirm : false,
      closeOnCancel : false
    }, function(isConfirm) {
      if (isConfirm) {
        $.ajax({
          url:basePath + "page/message_del.action",
          data:{
            "id":message_id
          },
          type:"get",
          dataType:"json",
          success:function(dataMap){
            if(dataMap!=null && dataMap.message=="success"){
              swal("删除!",
                  "已经成功删除.",
              "success");
              initTable();
            }else{
              swal("删除!",
                  "删除失败.",
              "error");
            }
          },
          error : function(errorMsg){
            swal("删除失败!",
                errorMsg,
            "error");
          }

        });
      } else {
        swal("Cancelled", "Your imaginary file is safe :)",
            "error");
      }
    });
  });

  $('.tcdPageCode').extendPagination({
    pageId : pageNo,
    totalCount : totalCount,
    showPage : 5,
    limit : pageSize,
    callback : function(pageNo, limit, totalCount) {
      messageSearch(pageNo);
    }
  });

});

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

如上面的  $("#serviceRepo_body").on('click','a.record_view',function(){});

分页js插件（page.js）, 同时引入jquery-1.11.1.min.js 和 bootstrap.js

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>
