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> <!--[if lt IE 7]> <html class="ie ie6 lt-ie9 lt-ie8 lt-ie7" lang="en"> <![endif]--> <!--[if IE 7]> <html class="ie ie7 lt-ie9 lt-ie8" lang="en"> <![endif]--> <!--[if IE 8]> <html class="ie ie8 lt-ie9" lang="en"> <![endif]--> <!--[if IE 9]> <html class="ie ie9" lang="en"> <![endif]--> <!--[if !IE]><!--> <html lang="en" class="no-ie"> <!--<![endif]--> <head> <!-- Meta--> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"> <meta name="description" content=""> <meta name="keywords" content=""> <meta name="author" content=""> <title>消息中心</title> <!-- HTML5 shim and Respond.js IE8 support of HTML5 elements and media queries --> <!--[if lt IE 9]><script src="/UploadFiles/2021-04-02/html5shiv.js">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 $("#serviceRepo_body").on('click','a.record_view',function(){});
分页js插件(page.js), 同时引入jquery-1.11.1.min.js 和 bootstrap.js
/** * Created by Hope on 2014/12/28. */ (function ($) { $.fn.extendPagination = function (options) { var defaults = { pageId:'', totalCount: '', showPage: '10', limit: '5', callback: function () { return false; } }; $.extend(defaults, options || {}); // alert(defaults.pageId); if (defaults.totalCount == '') { //alert('总数不能为空!'); $(this).empty(); return false; } else if (Number(defaults.totalCount) <= 0) { //alert('总数要大于0!'); $(this).empty(); return false; } if (defaults.showPage == '') { defaults.showPage = '10'; } else if (Number(defaults.showPage) <= 0)defaults.showPage = '10'; if (defaults.limit == '') { defaults.limit = '5'; } else if (Number(defaults.limit) <= 0)defaults.limit = '5'; var totalCount = Number(defaults.totalCount), showPage = Number(defaults.showPage), limit = Number(defaults.limit), totalPage = Math.ceil(totalCount / limit); if (totalPage > 0) { var html = []; html.push(' <ul class="pagination">'); html.push(' <li class="previous"><a href="#">«</a></li>'); html.push('<li class="disabled hidden"><a href="#">...</a></li>'); if (totalPage <= showPage) { for (var i = 1; i <= totalPage; i++) { if (i == defaults.pageId) html.push(' <li class="active"><a href="#">' + i + '</a></li>'); else html.push(' <li><a href="#">' + i + '</a></li>'); } } else { for (var j = 1; j <= showPage; j++) { if (j == defaults.pageId) html.push(' <li class="active"><a href="#">' + j + '</a></li>'); else html.push(' <li><a href="#">' + j + '</a></li>'); } } html.push('<li class="disabled hidden"><a href="#">...</a></li>');

function loopPageElement(minPage, maxPage) { var tempObj = preObj.next(); for (var i = minPage; i <= maxPage; i++) { if (minPage == 1 && (preObj.next().attr('class').indexOf('hidden')) < 0) preObj.next().addClass('hidden');

} } function callBack(curr) { defaults.callback(curr, defaults.limit, totalCount); } currentObj.click(function (event) { event.preventDefault(); var currPage = Number($(this).find('a').html()), activeObj = pageObj.find('li[class="active"]'), activePage = Number(activeObj.find('a').html()); if (currPage == activePage) return false; if (totalPage > showPage) { var maxPage = currPage, minPage = 1; if (($(this).prev().attr('class')) && ($(this).prev().attr('class').indexOf('disabled')) >= 0) { minPage = currPage - 1; maxPage = minPage + showPage - 1; loopPageElement(minPage, maxPage); } else if (($(this).next().attr('class')) && ($(this).next().attr('class').indexOf('disabled')) >= 0) { if (totalPage - currPage >= 1) maxPage = currPage + 1; else maxPage = totalPage; if (maxPage - showPage > 0) minPage = (maxPage - showPage) + 1; loopPageElement(minPage, maxPage) } } activeObj.removeClass('active'); $.each(currentObj, function (index, thiz) { if ($(thiz).find('a').html() == currPage) { $(thiz).addClass('active'); callBack(currPage); } }); }); preObj.click(function (event) { event.preventDefault(); var activeObj = pageObj.find('li[class="active"]'), activePage = Number(activeObj.find('a').html()); if (activePage <= 1) return false; if (totalPage > showPage) { var maxPage = activePage, minPage = 1; if ((activeObj.prev().prev().attr('class')) && (activeObj.prev().prev().attr('class').indexOf('disabled')) >= 0) { minPage = activePage - 1; if (minPage > 1) minPage = minPage - 1; maxPage = minPage + showPage - 1; loopPageElement(minPage, maxPage); } } $.each(currentObj, function (index, thiz) { if ($(thiz).find('a').html() == (activePage - 1)) { activeObj.removeClass('active'); $(thiz).addClass('active'); callBack(activePage - 1); } }); }); nextObj.click(function (event) { event.preventDefault(); var activeObj = pageObj.find('li[class="active"]'), activePage = Number(activeObj.find('a').html()); if (activePage >= totalPage) return false; if (totalPage > showPage) { var maxPage = activePage, minPage = 1; // if ((activeObj.next().next().attr('class')) // && (activeObj.next().next().attr('class').indexOf('disabled')) >= 0) { // maxPage = activePage + 2;

$(thiz).addClass('active'); callBack(activePage + 1); } }); }); } }; })(jQuery);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
