 * I am trying to combine javascript together as one external file to defer loading.
   I am not sure am I doing the correct thing. I got the javascript upload into 
   my root directory in a .js file.
 * Then I paste the the code below below before the </body> tag.
 *     ```
       <script defer="defer" type="text/javascript">
           window.onload=function(){
               var mycode;
               mycode=document.createElement("script");
               mycode.type="text/javascript";
               mycode.src="http://www.my site name.com/my external javascript file end with .js";
               document.getElementsByTagName("head")[0].appendChild(mycode);
           }
       </script>
       ```

 * I am not too sure. As for the external file link is working. It is just that 
   according to the page speed tool Pingdom Tool , the Combine external JavaScript
   has no effect.

 * Because according to pingdom, the page is finished loading. I doubt it executes
   all of your post-loading javascript as well. Go to your page and check the page
   source. Is the JavaScript there? Is it doing what it’s supposed to be doing?

 * The list of pages with Javascript are all there. That is where I got the whole
   bunch of javascript. I pasted them on the Notepad, minified them before I had
   it uploaded to my root directory.
 * Anyway, a while ago, when I went back to Pingdom Tools I notice I managed to 
   score 1/100 for Combine external Javascript. And now there newly created external
   file is included in the list!
