js-实现多列布局(瀑布流)

女生的网名这么多〃 提交于 2020-08-15 14:33:31

本文是使用js面向对象的思想实现多列布局(瀑布流)。第一行使用浮动进行布局,除第一行外使用定位进行布局。当然,使用面向过程也能实现,具体效果图和案例如下:

 css多列布局请参照本人另外一篇文章:css多列布局https://www.cnblogs.com/piaoyi1997/p/12705092.html

具体实现代码如下:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">*
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>*
    <style>*
        *{
            padding: 0;*
            margin: 0;*
        }
        .con{*
            margin: 0 auto;*
            position: relative;*
        }
        .box{
            float: left;
            padding: 8px;
        }
        .box .imgbox{*
            *padding: 4px;*
            border: 1px #000 solid;*
            border-radius: 6px;
        }
        .box .imgbox img{
            width: 200px;
            display: block;*
        }
    </style>
    <script>
        // 整个页面加载完成之后再执行
       * window.onload=function(){*
            new obj;*
        }
        *class obj{
            constructor(){
                this.aBox = document.querySelectorAll('.box');
                *this.con = document.querySelector('.con'); *  
                *this.clientW = document.documentElement.clientWidth;
                this.init();
                this.orderLine();
            }
           * init(){
                this.num = Math.floor(this.clientW/this.aBox[0].offsetWidth);
                *this.con.style.width=this.num*this.aBox[0].offsetWidth+'px';*
                this.minHeight = [];
                *for(var i=0;i<this.num;i++){
                    this.minHeight.push(this.aBox[i].offsetHeight);    
                }
                console.log(this.minHeight);
            }
            *orderLine(){
                for(var i=this.num;i<this.aBox.length;i++){
                    var min = Math.min(...this.minHeight);*
                    var index = this.minHeight.indexOf(min);
                    this.aBox[i].style.position='absolute';
                    this.aBox[i].style.left=index*this.aBox[0].offsetWidth+'px';*
                    this.aBox[i].style.top= min +'px';
                    this.minHeight[index]+=this.aBox[i].offsetHeight;
                }
            }
        }
    </script>
</head>
