如何通过jsp页面异步实现ajax？
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">

</result>
</action>
</package>
