常用的网页加载进度条
下面有三种方法，看本身需求：
一、顶部进度条
在html代码中间插入jq代码 执步履画。页面加载到哪部分，进度条就会相应的向前走几多
当全部加载完成后将loading进度条模块隐藏
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <meta name="viewport" content="width=device-width, initial-scale=1.0"> 6 <meta http-equiv="X-UA-Compatible" content="ie=edge"> 7 <script src="jquery.min.js"></script> 8 <title>顶部进度条</title> 9 <style> 10 .loading {position: fixed;top: 0;left: 0; width: 100%; height: 100%; background-color: #fff;} 11 .pic {width: 0;height: 10px;background-color: #c33;border-radius: 5px;} 12 </style> 13 </head> 14 <body> 15 <div class="loading"> 16 <div class="pic"></div> 17 </div> 18 <header> 19 <img src="http://file02.16sucai.com/d/file/2015/0128/8b0f093a8edea9f7e7458406f19098af.jpg" alt=""> 20 <img src="http://img12.3lian.com/gaoqing02/02/93/37.jpg" alt=""> 21 </header> 22 <script> 23 $(".loading .pic").animate({width: "20%"},100); 24 </script> 25 <section> 26 <img src="http://g.hiphotos.baidu.com/zhidao/pic/item/c83d70cf3bc79f3d6e7bf85db8a1cd11738b29c0.jpg" alt=""> 27 <img src="http://big5.wallcoo.com/photograph/summer_feeling/images/%5Bwallcoo.com%5D_summer_feeling_234217.jpg" alt=""> 28 </section> 29 <script> 30 $(".loading .pic").animate({width: "40%"},100); 31 </script> 32 <section> 33 <img src="http://cdn.duitang.com/uploads/item/201409/08/20140908130732_kVXzh.jpeg" alt=""> 34 <img src="http://file02.16sucai.com/d/file/2014/1006/e94e4f70870be76a018dff428306c5a3.jpg" alt=""> 35 </section> 36 <script> 37 $(".loading .pic").animate({width: "60%"},100); 38 </script> 39 <section> 40 <img src="http://b-ssl.duitang.com/uploads/item/201703/01/20170301163305_sCd8j.gif" alt=""> 41 </section> 42 <script> 43 $(".loading .pic").animate({width: "80%"},100); 44 </script> 45 <footer> 46 <img src="http://img.51ztzj.com/upload/image/20130417/201304172007_670x419.jpg" alt=""> 47 <img src="http://img0.imgtn.bdimg.com/it/u=1618007397,4183425847&fm=26&gp=0.jpg" alt=""> 48 </footer> 49 <script> 50 $(".loading .pic").animate({width: "100%"},100, function() { 51 $(".loading").fadeOut(); 52 }); 53 </script> 54 </body> 55 </html>
二、直接在页面插入关于加载的动态图，页面加载完再隐藏失
关于图片可以在这个网站找：https://loading.io/ 可以按照本身的需求调样式
固然，如果想本身写也可以，下面是博主本身用css3写的一个小动画
