解决“向终端显示内容产生时间延迟”

var remoteLoader = function remoteLoader(){
     function constructScriptTag(src){
     var script = window.document.createELement(‘SCRIPT‘);
     script.src = src;
     return script;
     }
     return{
       loadJS:function(script_url){
         if(typeof script_url === "object"){
           var frag = document.createDocumentFragment();
           for(var ind = 0;ind<script_url.length;ind++){
             frag.appendChild(constructScriptTag(script_url[ind]));  
           }
           window.document.getElementsByTagName(‘HEAD‘)[0].appendChild(frag.cloneNode(true));       
         }
       }else if(typeof script_url === "string"){
          window.document.getElementByTagName(‘HEAD‘)[0].appendChild(construcScriptTag(script_url));
        }

   <script>
     remoteLoader.loadJS("");//passing in a string
     remoteLoader.loadJS(["",""]);//passing in a array
