jquery插件splitScren实现页面分屏切换模板特效

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-4-4{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;}
