动态加载CSS，JS文件

var Head = document.getElementsByTagName('head')[0],style = document.createElement('style');
//文件所有加载完成显示DOM
function linkScriptDOMLoaded(parm){
	style.innerHTML = 'body{display:none}';//动态加载文件形成样式表渲染变慢，为了防止DOM结构在样式表渲染完成前显示形成抖动，先隐藏body，样式表读完再显示
	Head.insertBefore(style,Head.firstChild)
	var linkScript, linckScriptCount = parm.length, currentIndex = 0;	
	for ( var i = 0 ; i < parm.length; i++ ){
		if(/\.css[^\.]*$/.test(parm[i])) {
			linkScript = document.createElement("link");
			linkScript.type = "text/" + ("css");
			linkScript.rel = "stylesheet";
			linkScript.href = parm[i];
		} else {
			linkScript = document.createElement("script");
			linkScript.type = "text/" + ("javascript");
			linkScript.src = parm[i];
		}
		Head.insertBefore(linkScript, Head.lastChild)
		linkScript.onload = linkScript.onerror = function(){
			currentIndex++;
			if(linckScriptCount == currentIndex){
				style.innerHTML = 'body{display:block}';
				Head.insertBefore(style,Head.lastChild)
			}
		}
	}	
}
//异步加载css,js文件
function linkScript(parm, fn) {
	var linkScript;
	if(/\.css[^\.]*$/.test(parm)) {
