闲来无事，搞了个页面的分屏效果，先来看下效果：
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.
程序相关说明：
HTML结构：
<div class="header">
header
</div>
<div class="container" id="displayArea">
<!-- 分屏内容渲染区域 -->
</div>
<div class="footer">
<!--省略其他代码-->
</div>
js调用：
//分屏数据
var iframes = [
{
id:'frames_1',
frameName:'百度一下',
src:'http://www.baidu.com'
},
{
id:'frames_1',
frameName:'百度地图',
src:'http://map.baidu.com'
},
{
id:'frames_1',
frameName:'百度下',
src:'http://www.baidu.com'
},
{
id:'frames_1',
frameName:'百度视频',
src:'http://v.baidu.com'
},
{
id:'frames_1',
frameName:'百度新闻2',
src:'http://news.baidu.com'
},
{
id:'frames_1',
frameName:'test6',
src:'6.html'
},
{
id:'frames_1',
frameName:'百度新闻',
src:'http://news.baidu.com'
},
{
id:'frames_1',
frameName:'88888',
src:'6.html'
},
{
id:'frames_1',
frameName:'百度更多',
src:'http://www.baidu.com/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('removeSettingCls',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;}
