原生js实现瀑布流效果

本文实例为大家分享了js实现瀑布流效果的具体代码，供大家参考，具体内容如下

CSS样式：

<style>
.cont{margin: 0 auto;position: relative;}
.box{float: left;padding: 5px;}
.imgbox{border: black solid 1px;padding: 5px;border-radius: 5px;}
.imgbox img{width: 200px;display: block;}
</style>

HTML结构:

<div class="cont">
<div class="box">
<div class="imgbox">
<img src="img/1.jpg" >
</div>
</div>
//......此处省略雷同代码
<div class="box">
<div class="imgbox">
<img src="img/2.jpg" >
</div>
</div>
</div>

JavaScript代码：

<script>
onload = function(){
var wf = new WaterF();
wf.init();
}
class WaterF{
constructor(){
this.clientW = document.documentElement.clientWidth;
this.abox = document.querySelectorAll(".box");
this.cont = document.querySelector(".cont");
}
init(){
this.maxNum = parseInt(this.clientW / this.abox[0].offsetWidth);
this.cont.style.width = this.maxNum * this.abox[0].offsetWidth + "px";
this.firstLine();
this.otherLine();
}
firstLine(){
this.heightArr = [];
for(var i=0;i<this.maxNum;i++){
this.heightArr.push(this.abox[i].offsetHeight);
}
}
otherLine(){
for(var i=this.maxNum;i<this.abox.length;i++){
var min = Math.min(...this.heightArr);
var minIndex = this.heightArr.indexOf(min);
this.abox[i].style.position = "absolute";
this.abox[i].style.top = min + "px";
this.abox[i].style.left = minIndex * this.abox[0].offsetWidth + "px";
this.heightArr[minIndex] = this.heightArr[minIndex] + this.abox[i].offsetHeight;
}
}
}
</script>
