jQuery.lazyload详解

<script src="http://libs.baidu.com/jquery/1.9.1/jquery.min.js"></script> <script src="http://file.ithome.com/js/jquery.lazyload.js"></script>   jQuery实现图片延迟加载,不知道是否可以节省带宽呢?   有人知道吗?   这究竟只是一个视觉特效还是真的能延迟加载减少服务器的请求呢?   <script type="text/javascript" src="<?php bloginfo('template_directory');?>/js/jquery.lazyload.js"></script>   <script type="text/javascript">   $(function() {   $("img").lazyload({   effect : "fadeIn"   });   });   </script>   其中img是延迟加载所有图片,也可以根据不同模板作相应改动,比如我这个主题,可以改成#post img,这样只延迟加载#post 容器内的图片,否则可能影响到侧边图片的加载,主要是留言者头像可能会最后加载;   fadeIn是图片显示效果   这样基本就可以了!   如果上面的功能可能没有达到你的要求

WooCommerce - Custom thumbnails and default fall back image placeholder

我的梦境 提交于 2019-12-10 09:36:51

Django-CMS - Global placeholder?

被刻印的时光 ゝ 提交于 2019-12-10 04:35:06
问题 Is there any way to make global placeholder in my base template? I need it to be the same on every page (banners list). How can I do that? 回答1: I usually create a page in my CMS that isn't published, but contains placeholders that I would like to use elsewhere (footer/headers) etc. Make a new template extra_placeholders.html : {% extends "base.html" %} {% load cms_tags %} {% block content %} {% placeholder "Banner-List" %} {% endblock %} add it to your settings: CMS_TEMPLATES = ( ('my/path

Why is a transition property on the placeholder pseudoelement valid in Chrome?

狂风中的少年 提交于 2019-12-10 01:12:05
问题 I was goofing around with the ::placeholder pseudoelement on Codepen (Chrome 59.0.3071) when I noticed something odd. (please see my JSFiddle) In brief, this CSS should not enable a transition of the ::placeholder color over 2s: input::placeholder {color:red;transition:2s;} input:hover::placeholder {color:green} Using Firefox, there is no color transition over a 2 second interval on hover (this appears to be correct according to this section of a W3C spec and this section of a different one -

context:property-placeholder

泪湿孤枕 提交于 2019-12-09 16:52:51
这个在spring中配置文件中是非常常用的。 一、context:property-placeholder大大的方便了我们一些配置的加载,尤其是数据库方面 同样也方便了我们系统中的一些设置: 二、ignore-unresolvable 同个模块中如果出现多个context:property-placeholder ,location properties文件后,运行时出现Could not resolve placeholder 'key' in string value${key}。原因是在加载第一个context:property-placeholder时会扫描所有的bean,而有的bean里面出现第二个 context:property-placeholder引入的properties的占位符${key},此时还没有加载第二个property-placeholder,所以解析不了${key}。 解决: 办法一,可以将通过模块的多个property-placeholder合并为一个,将初始化放在一起。 方法二,添加ignore-unresolvable="true",这样可以在加载第一个property-placeholder时出现解析不了的占位符进行忽略掉。 来源: https://www.cnblogs.com/javabianhua/p/12011915.html
