I have nothing to do, so I created a split-screen effect for the page. Let’s take a look at the effect first:

For the purpose of customizable width and height, the screen blocks are controlled by CSS and js. It is estimated that the effect of the equal division module is average.

Procedure related instructions:

HTML structure: 

<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 call: 

//分屏数据

splitScreen.js related code description:

1. Define a class

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 main method

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() method description:

The main purpose is to switch different Classes according to different split-screens and control the split-screen layout through CSS classes. The advantage of writing this way is that you can customize the width and height of the layout, but it is more cumbersome. As follows: 

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");
    }
