jquery,分屏切换
web前端-js教程
闲来无事，搞了个页面的分屏效果，先来看下效果：
ionic 源码分析,ubuntu 降核,tomcat启动有哪些方式,爬虫缸蜗牛,php大型项目框架,广平seo关键词优化lzw
出于可自定义宽高的目的,屏幕分块由CSS控制，由js控制估计等分模块效果一般.
租车app 源码,vscode看动漫,atrix Ubuntu,tomcat 集群 卡死,c sqlite 注意事項,人人商城应用插件安装,前端适合新手学习的框架技术,抖音爬虫api官网,电影网站源码 php,广东seo哪家不错,微信 电脑网站支付宝,网页全屏效果插件,wordpress 找回密码页面模板lzw

HTML结构：
header
js调用：
//分屏数据var iframes = [{ id:frames_1, frameName:百度一下, src:\},{ id:frames_1, frameName:百度地图, src:\},{ id:frames_1, frameName:百度下, src:\},{ id:frames_1, frameName:百度视频, src:\},{ id:frames_1, frameName:百度新闻2, src:\},{ id:frames_1, frameName: est6, src:6.html},{ id:frames_1, frameName:百度新闻, src:\},{ id:frames_1, frameName:88888, src:6.html},{ id:frames_1, frameName:百度更多, src:/more/} ];//自适应屏幕window.onload = function(){ Panel.resize();}window.onresize = function(){ Panel.resize();}//初始化分屏var splitScreen = new splitScreen($(#displayArea),iframes);//监听removeSettingCls自定义事件splitScreen._on( emoveSettingCls,function(){ splitScreen.toggleTopbar(function(){ $(.ulTab li[data-fp="setting"]).removeClass(currentLi);});});//分屏切换function changeModel(obj){ var fpmodel = $(obj).attr(data-fp); if(fpmodel !="setting"){splitScreen.screenMode(fpmodel,function(){ $(obj).addClass(currentLi).siblings().removeClass(currentLi);}); }else{splitScreen.toggleTopbar(function(){ $(obj).toggleClass(currentLi);}); }}
splitScreen.js相关代码说明：
1.定义一个类
var splitScreen = function(elem, options) { this.elem = elem; //分屏模块渲染区域元素 this.options = options;//分屏链接数据 this.initialize.apply(this); //初始化初始化分屏}
2.prototype主要方法
splitScreen.prototype= { initialize: function() {},//初始化方法 screenMode: function(){},//分屏方法 renderPanel:function(){},//渲染分屏DOM bindPanel:function(){} //事件监听 };
3.screenMode()方法说明：
主要是根据不同的分屏切换不同的Class，通过CSS类去控制分屏布局.这样写的好处应该是可以自定义布局的宽高大小，但是比较繁琐。如下：
switch (Number(mode)) {case 1: this.data = [[fp-1-1] ]; this.defaultShow = [0]; break;case 2: this.data = [[fp-2-1],[fp-2-2] ]; this.defaultShow = [1, 2]; break;case 3: this.data = [[fp-3-1],[fp-3-2, fp-3-3] ]; this.defaultShow = [1, 2, 3]; break;case 4: this.data = [[fp-4-1, fp-4-2],[fp-4-3, fp-4-4] ]; this.defaultShow = [4, 1, 2, 3]; break;case 5: this.data = [[fp-5-1],[fp-5-2],[fp-5-3, fp-5-4, fp-5-5] ]; this.defaultShow = [4, 5, 1, 2, 3]; break;case 6: this.data = [[fp-6-1],[fp-6-2, fp-6-3],[fp-6-4, fp-6-5, fp-6-6] ]; this.defaultShow = [4, 5, 6, 7, 8, 8]; break;default: alert("不支持" + mode + "分屏"); }
CSS布局控制：
.fp-box{position:absolute;border:1px solid #000;background:#fff;}.fp-1-1{top:0;left:0;right: 0;bottom: 0;}.fp-2-1{top:0;left:0;right: 300px;bottom: 0;}.fp-2-2{top:0;right: 0px;bottom: 0; width: 300px;}.fp-3-1{top:0;left:0;right: 300px;bottom: 0;}.fp-3-2{top:0;right: 0;width:300px;height:50%;}.fp-3-3{top:50%;right: 0;bottom: 0;width:300px;}.fp-4-1{top:0;left:0;right: 50%;height:50%;}.fp-4-2{top:50%;left:0;right: 50%;bottom: 0;}.fp-4-3{top:0;right: 0;width:50%;height:50%;}.fp-4-4{top:50%;right: 0;bottom: 0;width:50%;} .fp-5-1{top:0;left:0;right: 300px;bottom: 252px;}.fp-5-2{top:0px;width:300px;right: 0;bottom: 252px;}.fp-5-3{height: 250px;left:0;width:30%;bottom: 0;}.fp-5-4{height: 250px;left:30%;width:30%;bottom: 0;}.fp-5-5{height: 250px;left:60%;bottom: 0;right: 0;}.fp-6-1{top:0;left:0;right: 300px;bottom: 252px;}.fp-6-2{top:0;width:300px;right: 0;height:250px;}.fp-6-3{top:250px;width:300px;right: 0;bottom: 252px;}.fp-6-4{height: 250px;left:0;width:30%;bottom: 0;}.fp-6-5{height: 250px;left:30%;width:30%;bottom: 0;}.fp-6-6{height: 250px;left:60%;bottom: 0;right: 0;}
