前端网页加载进度条的实现有三种方式,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
!DOCTYPE html> html> head> meta charset="UTF-8"> meta name="viewport" content="width=device-width, inITial-scale=1.0"> meta http-equiv="X-UA-Compatible" content="ie=Edge"> script src="jquery.min.js"> /script> title> 顶部进度条/title> style> .loading { position: fixed; top: 0; left: 0; width: 100%; height: 100%; background-color: #fff; } .pic { width: 0; height: 10px; background-color: #c33; border-radius: 5px; } /style> /head> body> div> div> /div> /div> header> img src="http://file02.16sucai.COM/d/file/2015/0128/8b0f093a8edea9f7e7458406f19098af.jpg" alt=""> img src="http://img12.3lian.com/gaoqing02/02/93/37.jpg" alt=""> /header> script> $(".loading .pic").aniMATE({ width: "20%"} ,100); /script> section> img src="http://g.hiphotos.baidu.com/zhiDAO/pic/item/c83d70CF3bc79f3d6e7bf85db8a1cd11738b29c0.jpg" alt=""> img src="http://Big5.wallcoo.com/photograph/summer_feeling/images/%5Bwallcoo.com%5D_summer_feeling_234217.jpg" alt=""> /section> script> $(".loading .pic").animate({ width: "40%"} ,100); /script> section> img src="http://cdn.duitang.com/uploads/item/201409/08/20140908130732_kVXzh.jpeg" alt=""> img src="http://file02.16sucai.com/d/file/2014/1006/e94e4f70870be76a018DFf428306c5a3.jpg" alt=""> /section> script> $(".loading .pic").animate({ width: "60%"} ,100); /script> section> img src="http://b-ssl.duitang.com/uploads/item/201703/01/20170301163305_sCd8j.gif" alt=""> /section> script> $(".loading .pic").animate({ width: "80%"} ,100); /script> footer> img src="http://img.51ztzj.com/upload/image/20130417/201304172007_670x419.jpg" alt=""> img src="http://img0.imgtn.bdimg.com/it/u=1618007397,4183425847& fm=26& gp=0.jpg" alt=""> /footer> script> $(".loading .pic").animate({ width: "100%"} ,100, function() { $(".loading").fadeOut(); } ); /script> /body> /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
!DOCTYPE html> html> head> meta charset="UTF-8"> meta name="viewport" content="width=device-width, initial-scale=1.0"> meta http-equiv="X-UA-Compatible" content="ie=edge"> title> css3动画进度条/title> style> .loading { position: fixed; top:0; left:0; width: 100%; height: 100%; background-color: #fff; } .pic { position: absolute; top: 0; bottom: 0; left: 0; right: 0; margin: auto; width: 100px; height:40px; } .pic i { float:left; margin: 0 2px; width: 6px; height: 30px; background-color: indigo; transform: scaleY(0.4); animation: load 1.2s infinite; } .pic i:nth-child(2){ -webkit-animation-delay: 0.1s; animation-delay: 0.1s; } .pic i:nth-child(3){ -webkit-animation-delay: 0.2s; animation-delay: 0.2s; } .pic i:nth-child(4){ -webkit-animation-delay: 0.3s; animation-delay: 0.3s; } .pic i:nth-child(5){ -webkit-animation-delay: 0.4s; animation-delay: 0.4s; } .pic i:nth-child(6){ -webkit-animation-delay: 0.5s; animation-delay: 0.5s; } @-webkit-keyframes load { 0%,40%,100%{ -webkit-transform: scaleY(0.4); transform: scaleY(0.4)} 20%{ -webkit-transform: scaleY(1); transform: scaleY(1)} } @keyframes load { 0%,40%,100%{ -webkit-transform: scaleY(0.4); transform: scaleY(0.4)} 20%{ -webkit-transform: scaleY(1); transform: scaleY(1)} } /style> script src="jquery.min.js"> /script> script> document.onreadystatechange = function() { // 页面状态发生改变时触发 if(document.readyState == "complete") { // 页面加载完成时隐藏 $(".loading").fadeOut(); } } /script> /head> body> div> div> i> /i> i> /i> i> /i> i> /i> i> /i> i> /i> /div> /div> img src="http://file02.16sucai.com/d/file/2015/0128/8b0f093a8edea9f7e7458406F19098af.jpg" alt=""> img src="http://img12.3lian.com/gaoqing02/02/93/37.jpg" alt=""> img src="http://g.hiphotos.baidu.com/zhidao/pic/item/c83d70cf3bc79f3d6e7bf85db8a1cd11738b29c0.jpg" alt=""> img src="http://big5.wallcoo.com/photograph/summer_feeling/images/%5Bwallcoo.com%5D_summer_feeling_234217.jpg" alt=""> img src="http://cdn.duitang.com/uploads/item/201409/08/20140908130732_kVXzh.jpeg" alt=""> img src="http://file02.16sucai.com/d/file/2014/1006/e94e4f70870be76a018dff428306c5a3.jpg" alt=""> img src="http://b-ssl.duitang.com/uploads/item/201703/01/20170301163305_sCd8j.gif" alt=""> img src="http://img.51ztzj.com/upload/image/20130417/201304172007_670x419.jpg" alt=""> img src="http://img0.imgtn.bdimg.com/it/u=1618007397,4183425847& fm=26& gp=0.jpg" alt=""> /body> /html>
三、实时获取数据的进度条(百分比)
代码如下
!DOCTYPE html> html> head> meta charset="UTF-8"> meta name="viewport" content="width=device-width, initial-scale=1.0"> meta http-equiv="X-UA-Compatible" content="ie=edge"> title> 百分比进度条/title> style> .loading { position: fixed; top:0; left:0; width: 100%; height: 100%; background-color: #fff; } .pic { position: absolute; top: 0; bottom: 0; left: 0; right: 0; margin: auto; width: 100px; height:100px; line-height: 55px; text-align: @R_360_934@; font-Size: 22px; } .pic span { display: inline-block; position: absolute; top: 10px; left: 10px; width: 80px; height: 80px; border-radius: 50%; box-shadow: 0 3px 0 #999; -webkit-animation: move 1s infinite linear; animation: move 1s infinite linear; } @-webkit-keyframes move { 0%{ -webkit-transform: rotate(0deg); transform: rotate(0deg); } 100%{ -webkit-transform: rotate(360deg); transform: rotate(360deg); } } @keyframes move { 0%{ -webkit-transform: rotate(0deg); transform: rotate(0deg); } 100%{ -webkit-transform: rotate(360deg); transform: rotate(360deg); } } /style> script src="jquery.min.js"> /script> script> $(function() { VAR img = $("img"); // 获取所有的img元素 var num = 0; // 用来存储已加载的图片个数 img.each(function(i) { // 遍历所有图片 var oImg = new Image(); oImg.onload = function() { // onload 图片加载完成后执行 num++; $(".pic p").html(parseInt(num / img.length * 100) + '%'); if(num > = img.length) { $(".loading").fadeOut(); // 页面加载完成后隐藏 } } oImg.src = img[i].src; } ) } ) /script> /head> body> div> div> span> /span> p> 0%/p> /div> /div> img src="http://file02.16sucai.com/d/file/2015/0128/8b0f093a8edea9f7e7458406f19098af.jpg" alt=""> img src="http://img12.3lian.com/gaoqing02/02/93/37.jpg" alt=""> img src="http://g.hiphotos.baidu.com/zhidao/pic/item/c83d70cf3bc79f3d6e7bf85db8a1cd11738b29c0.jpg" alt=""> img src="http://big5.wallcoo.com/photograph/summer_feeling/images/%5Bwallcoo.com%5D_summer_feeling_234217.jpg" alt=""> img src="http://cdn.duitang.com/uploads/item/201409/08/20140908130732_kVXzh.jpeg" alt=""> img src="http://file02.16sucai.com/d/file/2014/1006/e94e4f70870be76a018dff428306c5a3.jpg" alt=""> img src="http://b-ssl.duitang.com/uploads/item/201703/01/20170301163305_sCd8j.gif" alt=""> img src="http://img.51ztzj.com/upload/image/20130417/201304172007_670x419.jpg" alt=""> img src="http://img0.imgtn.bdimg.com/it/u=1618007397,4183425847& fm=26& gp=0.jpg" alt=""> /body> /html>
