scrollload.js's Introduction

scrollLoad.js

scrollLoad.js是一款jQuery滚动响应加载图片的插件。

现在很多网页上都是有很多图片资源需要进行请求加载,如果页面图片内容太多,那么网页加载的速度就会变慢,不能达到理想的秒开效果,特此,scrollLoad.js可以延迟加载图片,当浏览器滚动到这个可视区域后,在进行图片的加载。

使用方法

在页面中引入scrollLoad.js文件。

<script src='js/jquery.scrollLoad.js'></script>

HTML结构

使用一个**<div id="warp">**作为目标点,需要加载图片的区域的位置。

<!--图片容器-->
<div id = "warp">
		<img src="loaddig.jpg" data-src="/image/meilideguniang.jpg">
</div>  

插件会自动查找 图片容器内的所有图片,id为warp标签下的所有img的标签,其中 img 的 src 为占位图片,data-src 为需要展示的图片的真实地址,它会自动替换图片的地址进行展示。

初始化插件

在页面DOM元素加载完毕之后,可以通过下面的方法来初始化插件。

$("#warp").scrollLoad()

配置参数

参数 默认值 描述 类型
src data-src 存放图片真实路径的属性 string
tiem 300 切换时间 number
