这篇文章主要介绍了jQuery实现瀑布流的取巧做法分享,需要的朋友可以参考下

   

分析：瀑布流，做法有2种

（1）绝对定位方案：每个单元格设置为绝对定位，通过计算，分别设置 top , left 即可实现

（2）浮动方案：弄N列布局（浮动），然后图片数据，按顺序依次插入，如N为3列 ，第一张图片插入到第一列，第二张图片插入到第二列，第三张图片插入到第三列，第四张图片插入到第一列........这样循环插入（不能自适应）

CSS与HTML代码：

 

复制代码 代码如下:
body,ul,li{margin:0;margin:0;}
ul{list-style:none;}
.clearfix:after{visibility:hidden;display:block;font-size:0;content:" ";clear:both; height:0;}.clearfix{*zoom:1}
/*瀑布流*/
.wallList{width:860px;}
.wallList li{float:left;display:inline;margin-right:16px;}
.wallList li a{background:#eee;border:1px solid #ccc;padding:5px 5px 0 5px;display:block;margin-bottom:10px;}
.wallList li a:hover{border-color:#f60;}
.wallList li .name{display:block;text-align:center;padding:8px 0;}
.loadTips{text-align:center;padding:15px 0;}

 

 

复制代码 代码如下:
<div class="wallList" id="wallList">
<ul class="clearfix">
<li></li>
<li></li>
<li></li>
</ul>
<p class="loadTips" id="loadTips"><span>正在加载......</span></p>
</div>

 

使用jQuery实现，大概思路如下：

　　（1）获取N列中 最小的高度值，JS提供的API是Math.min()，但这个API最多只能传入 2 个参数，所以就需要用aplly来扩展，Math.min.apply(null,[xxx,xxx,xxxx,xxxx])
（2）给 window 绑定 scroll事件，下拉的时候获取 $(document).scrollTop() ， 当 $(document).scrollTop() 大于 最小的高度值，就ajax请求url，如果有数据，就往页面插入HTML结构，没有则提示 “加载完”，然后window解绑此事件

 

复制代码 代码如下:
// 数据格式
var testJson = {
"status":1,
"data":[
