jQuery lazyload插件和回调函数 [英] Jquery lazyload plugin and callback function
问题描述
我从此网站 http://www.appelsiini.net/projects/lazyload 下载jQuery lazyload插件.
i download jquery lazyload plugin from this site http://www.appelsiini.net/projects/lazyload.
从他们的文档中,我还没有发现可以通过lazyload插件使用或不使用任何回调.
from their doc i have not found that one can use any callback or not with lazyload plugin.
假设我的html看起来像
suppose my html look like
<div id="gallery" class="busy"><img src="blah.jpg" /></div>
<div id="gallery" class="busy"><img src="blah2.jpg" /></div>
<div id="gallery" class="busy"><img src="blah3.jpg" /></div>
我的脚本喜欢
$("#gallery img").lazyload();
class busy只会在div的中心设置一个忙碌的图像.所以我需要一个回调,并且从回调中需要检测图像下载是否完成(如果完成),那么我只需从图像标记的相应父div中删除该类即可.
class busy will just set a busy image at the center of div. so i need a callback and from the callback i need to detect image download completed or not if completed then i just remove the class from corresponding parent div of image tag .
因此,请向我展示使用lazyload实现回调的方法,并且还需要示例代码,通过该示例代码,我可以从图像标签的相应父div中删除该类.
so please show me the way to implement callback with lazyload and also need sample code by which i can remove the class from corresponding parent div of image tag .
谢谢
推荐答案
我有同样的问题.做了一些搜索,来到这里,找到了答案.这是我拥有的水,并且为我工作:
I had the same question. Did some searching, came here, and found the answer. This is wat I have, and works for me:
$(this).lazyload({
effect : 'fadeIn',
load : function()
{
console.log($(this)); // Callback here
}
});
