为WordPress网站顶部添加一个加载进度条

CSS代码，可以放到style.css也可以放到css目录里的mian.css里。

@keyframes loading-bar-move{0%{width:0;opacity:0}%{width:0;opacity:0}70%{width:100%;opacity:1}100%{width:100%;opacity:0}}
@-moz-keyframes loading-bar-move{0%{width:0;opacity:0}70%{width:100%;opacity:1}100%{width:100%;opacity:0}}
@-o-keyframes loading-bar-move{0%{width:0;opacity:0}70%{width:100%;opacity:1}100%{width:100%;opacity:0}}
@-webkit-keyframes loading-bar-move{0%{width:0;opacity:0}70%{width:100%;opacity:1}100%{width:100%;opacity:0}}
.progress{border-radius: 0;position: absolute;left:0;top:0;height:5px;animation:loading-bar-move 2s;-moz-animation:loading-bar-move 2s;-webkit-animation:loading-bar-move 2s;-o-animation:loading-bar-move 2s;}
.progress-bar{width:100%;}

JQ代码，可以放到JS文件夹里面的main.js里。

//进度条加载！
$(document).on("click","a",function(){
 if( $(window).width()<768 ) return;
 if( $(this).attr('target')=='_blank' ) return;
 if( $(this).parent('#pagination-comments').length>0 ) return;
 var url = $(this).attr('href');
 var u = document.createElement('a');
 u.href = url,
 ru = u.protocol+u.hostname+u.pathname+u.search,
 l = location,
 rl = l.protocol+l.hostname+l.pathname+l.search;
 if(ru==rl) return;
 var urlreg=/^((https|http|ftp|rtsp|mms)?://)+[A-Za-z0-9]+.[A-Za-z0-9]+[/=?%-&_~`@[]':+!]*([^<>""])*$/;
 if(urlreg.test(url)){
 n = $('.header');
 if( n.children('.progress').length<=0 ){
 n.prepend('<div class="progress"><div class="progress-bar progress-bar-success progress-bar-striped active" role="progressbar"></div></div>');
 }
 }
});
