瀑布流网页页面效果目前是一种很常见的布局，下面使用原生js实现一个瀑布流效果，附代码如下
复制代码，图片路径自己修改即可
CSS代码
<style type="text/css">
*{
margin:0;
padding:0;
}
img{
vertical-align: bottom;
}
#box{
position: relative;
margin:0 auto;
width: 780px;
}
#box .panel{
position: absolute;
}
#box .panel img{
margin:10px;
padding:10px;
width: 220px;
background: #fff;
border-radius: 5px;
box-shadow: 0 0 8px #ccc;
}
</style>
HTML代码
<body> <div id="box"> <div class="panel"><img src="img/1.jpg"></div> <div class="panel"><img src="img/2.jpg"></div> <div class="panel"><img src="img/3.jpg"></div> <div class="panel"><img src="img/4.jpg"></div> <div class="panel"><img src="img/5.jpg"></div> <div class="panel"><img src="img/6.jpg"></div> <div class="panel"><img src="img/7.jpg"></div> <div class="panel"><img src="img/8.jpg"></div> <div class="panel"><img src="img/9.jpg"></div> <div class="panel"><img src="img/10.jpg"></div> <div class="panel"><img src="img/11.jpg"></div> <div class="panel"><img src="img/12.jpg"></div> <div class="panel"><img src="img/13.jpg"></div> <div class="panel"><img src="img/14.jpg"></div> <div class="panel"><img src="img/15.jpg"></div> <div class="panel"><img src="img/16.jpg"></div> <div class="panel"><img src="img/17.jpg"></div> <div class="panel"><img src="img/18.jpg"></div> <div class="panel"><img src="img/19.jpg"></div> <div class="panel"><img src="img/20.jpg"></div> </div> </body>
JS代码
<script type="text/JavaScript"> let box = document.getElementById('box'); let panel = Array.from(box.children); // 声明panel的宽度 const PANEL_WIDTH = panel[0].offsetWidth; // 声明列数 let totalColumn = Math.trunc(document.documentElement.clientWidth/PANEL_WIDTH); // 就算box的宽度 box.style.width=totalColumn*PANEL_WIDTH+'PX'; // 声明图片的宽度 const IMG_WIDTH =220; // 记录每列的高度 let columnHeight = []; panel.forEach(function(v, k){ if(k< totalColumn){ v.style.left=k*PANEL_WIDTH+'PX'; v.style.top = 0; // 记录列的高度 columnHeight.push(v.offsetHeight); }else{ //剩余的图片找最低的列高度 let minHeight = Math.min(...columnHeight); // 查找最小值在数组中的小标 let minHeightKey = columnHeight.indexOf(minHeight); // 指定位置 v.style.left=minHeightKey*PANEL_WIDTH+'px'; v.style.top = minHeight+'px'; // 更新列的高度 columnHeight[minHeightKey]=minHeight+v.offsetHeight; } }) </script>
