目的：XXXX项目中，很多的弹窗是利用freemarker的网页标签追加的形式实现的，网页弹框只是将隐藏的div显示出来，这样会使网页在预加载时速度变慢，增加页面加载和响应时间

解决方法如下：<已分中心管理的添加分中心弹框实现机制为例>

1.弹框页面部分的html代码和css抽离

html : html/configure/layer-win/_group-add-layer.html

css : css/common/componnentWin.css <自定义弹窗通用样式>

子层html: _group-add-layer.html

<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>group Add</title> </head> <link rel="stylesheet" type="text/css" href="../../../js/lib/datePicker/skin/WdatePicker.css" /> <link rel="stylesheet" type="text/css" href="../../../css/common/componnentWin.css" /> <body> ···· </body> <script type="text/javascript" src="../../../js/jquery-1.9.1.js"></script> <script type="text/javascript" src="../../../js/lib/layer/layer.js"></script> <script type="text/javascript" src="../../../js/scooper/scooper.tool.xiacy.js"></script> <script type="text/javascript" src="../../../js/configure/layer-win/group-new-add.js"></script> <script type="text/javascript"> </script> </html>

父层html : group-manager.html

<#include "/html/config/configure.html"/> <@menuConfig likey="stationGroup"> <link rel="stylesheet" type="text/css" href="${contextPath}/css/configure/group-manager.css" /> <link rel="stylesheet" type="text/css" href="${contextPath}/css/lib/userLibs/page-plugin.css"> <script type="text/javascript" src="${contextPath}/js/lib/layer/layer.js"></script> <script type="text/javascript" src="${contextPath}/js/lib/userLibs/page-load.js"></script> <script type="text/javascript" src="${contextPath}/js/scooper/scooper.tool.xiacy.js"></script> <script type="text/javascript" src="${contextPath}/js/configure/group-manager.js"></script> ····· </@menuConfig>

通用弹窗 html :

<div id = "addNewGroupWin" class = "capsule-win show"> <div class = "capsule-win-top" title = "添加分中心"><span>添加分中心</span></div> <div class = "capsule-win-center"> <div class = "capsule-item" id = "oldDevSearch"> <div class = "item-left input_required" >名称</div> <div class = "item-right"> <input id = "newGroupName" class = "sc_validate" title = "分中心名称" type="text" placeholder="请输入分中心名称" scvalidate='{"required":true,"format":"string"}'/> </div> </div> <div class = "capsule-item"> <div class = "item-left input_required">经度</div> <div class = "item-right"> <input id = "newGroupLng" class = "sc_validate" title= "分中心经度" type="text" placeholder="请输入0-180的数字" scvalidate='{"required":true,"format":"lng"}'/> </div> </div> <div class = "capsule-item"> <div class = "item-left input_required">纬度</div> <div class = "item-right"> <input id = "newGroupLat" class = "sc_validate" title = "分中心纬度" type="text" placeholder="请输入0-90的数字" scvalidate='{"required":true,"format":"lat"}'/> </div> </div> <div class = "capsule-item" id = "processSNOLDIV"> <div class = "item-left input_required">描述</div> <div class = "item-right"> <textarea id = "newGroupDesc" class = "sc_validate" title = "分中心描述" scvalidate='{"required":true,"format":"string"}'></textarea> </div> </div> </div> <div class = "capsule-win-bottom"> <input id="addNewGroupSure" class = "btn-bottom centerfix btn-succ" type="button" value="确定"/> <input id="addNewGroupCancle" class = "btn-bottom btn-cancel" type="button" value="取消"/> </div> </div>

2.子父层都需要引入layer.js

3.子层js

/** * <分中心管理> * 添加分中心 * Author : Yiyuery * Date : 2016/10/19 */ ;(function($,w,document,undefined){ $(document).ready(function(){ validatorInit(); clickEventBind(); }); var addGroupValidator = new Validator(); var contextPath = "/ZJDZYW"; /** * 表单验证初始化 * @returns */ function validatorInit(){ addGroupValidator.init(function(obj, msg){ layer.tips(msg,obj,{ style: ['background-color:#78BA32; color:#fff', '#78BA32'], maxWidth:185, time: 2000, tips: 1, }); }); } /** * 点击事件绑定 * @returns */ function clickEventBind(){ addNewGroupClick(); } /** * 分中心相关点击事件 * @returns */ function addNewGroupClick(){ $("#addNewGroupSure").click(function(){ addNewGroupSure(); }); $("#addNewGroupCancle").click(function(){ addNewGroupCancle(); }); } /** * 添加新的分中心 [确定] * @returns */ function addNewGroupSure(){ validatorInput(); } /** * 添加分中心 [取消] */ function addNewGroupCancle(){ closeLayerWin(); } /** * 关闭当前打开的layer弹窗 */ function closeLayerWin(){ var index = parent.layer.getFrameIndex(window.name); parent.layer.close(index); //再执行关闭 } /** * 表单提交输入验证 */ function validatorInput(){ /** * 输入校验 */ if(!addGroupValidator.validate("addNewGroupWin")){ return; } var paras = { "group_name" : $("#newGroupName").val(), "longitude" : $("#newGroupLng").val(), "latitude" : $("#newGroupLat").val(), "group_desc" : $("#newGroupDesc").val(), }; $.ajaxSettings.async = false ; $.getJSON(contextPath+"/stationGroup/add", paras, function(resp){ if(resp.code !=undefined && resp.code == 0){ console.log("分中心列表刷新！"); } }); $.ajaxSettings.async = true ; closeLayerWin(); } })(jQuery,window,document);

4.父层js

$("#addGroup").click(function(){ layer.config({ path : '${contextPath}/js/lib/layer' }); index = layer.open({ type: 2, area: ['520px', '400px'], fix: false, //不固定 title: '', maxmin: false, scrollbar:false, shade:0.5, shadeColse:true, content:capsule.request.path.groupMan.layer.groupManAddLayerShow, end:function(){ loadGroupCenterInfo(); } }); });

loadGroupCenterInfo :父层js的方法，在关闭layer弹窗时调用父层方法刷新分中心列表

5.父层的layer弹窗此处是无法跳出父页面的所嵌套的iframe的，由于添加分中心的操作loadGroupCenterInfo，中嵌套着点击事件的重新激活clickEventInit该方法不是全局的，无法通过end传递到父页面中再次执行

/** * 加载分中心 */ function loadGroupCenterInfo(){ $.ajaxSettings.async = false ; $.getJSON(capsule.request.path.groupMan.getJson.loadCenterGroup,{},function(data){ $("#groupCenterArea").empty(); $.each(data.list,function(i,obj){ groupMap.setKeyValue(obj.id,obj.group_name); var count = obj.c_num; if(obj.c_num == null || obj.c_num == "null"){ count = 0; } var html = '<div id='+obj.id+'>' + '<img src="'+contextPath+'/image/Checkbox.png"/>'+obj.group_name+"("+count+")"+'<li title="编辑"></li></div>'; $("#groupCenterArea").append(html); }); clickEventInit(); }); $.ajaxSettings.async = true ; }

因此:当回调函数涉及当前层的函数互相调用时，是无法使用通用layer最外层弹框来实现的，只能在当前页面的js中重新模块化引入layer

[后来发现，其实是可以的，只需要将回调函数直接写在调用方法中即可，参见：javascript中的方法回调和父页面Iframe的方法调用]

layer.config({ path : '${contextPath}/js/lib/layer' }); index = layer.open({ type: 2, area: ['520px', '400px'], fix: false, //不固定 title: '', maxmin: false, scrollbar:false, shade:0.5, shadeColse:true, content:capsule.request.path.groupMan.layer.groupManAddLayerShow, end:function(){ loadGroupCenterInfo(); } });

6.通用弹窗样式css

@charset "utf-8"; /*-------功能性按钮------*/ body,html{ width:100%; height:100%; margin:0px; padding:0px; } .capsule-btn { height: 40px; width: 50px; background-color: #5093e1; border: 0; border-radius: 2px; color: #fff; margin: 15px 0px 10px 15px; float: left; } /*----------------------------------------- 弹框按钮 -------------------------------------*/ .capsule-win .btn-bottom{width: 100px; height: 40px; background-color: #4f94e0; font-size: 16px; border: none; color: #fff; -moz-border-radius: 3px; -khtml-border-radius: 3px; -webkit-border-radius: 3px; border-radius: 3px; cursor: pointer; margin-right: 10px;margin-top: 10px;} .centerfix{margin-left: 30%;} .btn-cancel {background-color: #f5f5f5 !important; border: 1px #c2c2c2 solid !important;; color: #333 !important;} .btn-succ {background-color: #1abd9b;} .btn-warn {background-color: #ec962f;} /*------------弹窗---------------*/ .capsule-win { width: 100%; min-height: 100%; -moz-border-radius: 5px; -khtml-border-radius: 5px; -webkit-border-radius: 5px; background-color: #fff; display: none; position: fixed; } .capsule-win-top { width: 100%; height: 50px; background-color: #4f94e0; line-height: 50px; color: #fff; font-size: 16px; } .capsule-win-center { width: 100%; min-height: 250px; padding: 20px 0px 20px 0px; margin:0px 1px 0px 1px; } .capsule-win-bottom { width: 100%; height: 60px; background-color: #ececec; padding: 0px; position: fixed; bottom: 1px; } .capsule-win-center .capsule-item { height: 50px !important; width: 100%; margin: 0px 2px 0px 2px; padding: 0px; } .capsule-win-center .capsule-item .item-left { width: 100px; text-align: right; margin: 10px 0px 0px 0px; float:left; } .capsule-win-center .capsule-item .item-right { width: 400px; float:right; } .capsule-win-center .capsule-item .item-right input[type=text]{ width:75%; height: 35px; } .capsule-win-center .capsule-item .item-right input[type=checkbox]{ width:20px; marin:2px -5px 2px 0px; padding:10px; } .capsule-win-center .capsule-item .item-right textarea{ width:75%; height:50px; margin-bottom: 10px; overflow-y:auto; } .capsule-win-center .capsule-item .item-right select{ width:90%; } .hide{ display : none; } .show{ display : block; } .capsule-win-center .capsule-item-table{ width: 445px; height: 120px; margin: 5px 10px 0px 75px; overflow-y:auto; } .capsule-win-center .capsule-item-table table{ border-collapse:collapse; width:100%; } .capsule-win-center .capsule-item-table table,th, td{ border: 1px solid #ccc; } .capsule-win-center .capsule-item-table th{ height:30px; text-align: center; } .capsule-win-center .capsule-item-table td{ text-align: center; } .capsule-win-center .capsule-item-table input[type=text] { width:100% !important; } .textCenter { text-align: center; } .capsule-win-top span { margin : 10px; }
