1 重新加载js的方法

var head = $("head").remove("script[role='reload']");
            $(" + "pt>" + " + "ipt>").attr({ role: 'reload', src: getRootPath()+"/js/video.js", type: 'text/javascript' }).appendTo(head);

2 重新加载css的方法

var link = document.createElement("link");
link.rel = "stylesheet";
link.type = "text/css";
link.href = getRootPath()+"/css/video.css";
document.getElementsByTagName("head")[0].appendChild(link);

function getRootPath() {
//获得根目录

var strFullPath = window.document.location.href;

var strPath = window.document.location.pathname;

var pos = strFullPath.indexOf(strPath); 

  var prePath = strFullPath.substring(0, pos); 

   var postPath = strPath.substring(0, strPath.substr(1).indexOf('/') + 1); 

   return (prePath + postPath);
}
