标签：html 改变 content ext nsf each 隐藏 ram meta 下面有三种方式，看自己需求： 一、顶部进度条 在html代码中间插入jq代码 执行动画。页面加载到哪部分，进度条就会相应的向前走多少 当全部加载完成后将loading进度条模块隐藏 二、直接在页面插入关于加载的动态图，页面加载完再隐藏掉 关于图片可以在这个网站找：https://loading.io/ 可以根据自己的需求调样式 当然，如果想自己写也可以，下面是博主自己用css3写的一个小动画 代码如下 三、实时获取数据的进度条（百分比） 代码如下 常用的网页加载进度条 标签：html 改变 content ext nsf each 隐藏 ram meta 原文地址：https://www.cnblogs.com/sunyan-blog/p/12109037.html 1 DOCTYPE html>
