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>
