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 class="groupItemDiv" id='+obj.id+'>'
+ '<img class="checkBoxLeftSite" src="'+contextPath+'/image/Checkbox.png"/>'+obj.group_name+"("+count+")"+'<li title="编辑" class="editGroup"></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();
}
});
