JS实现图片延迟加载(缓冲)，非常实用

<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="js/jquery.lazyload.js"></script> <script type="text/javascript"> jQuery(document).ready(function($){$("img").lazyload({placeholder:"images/grey.gif",effect:"fadeIn"});}); </script>
