Display Files / Folders from a Document Library in Sharepoint

Below is the code to display documents / folders from a library in a Sharepoint environment, in a Tree View.

we are using SPServices and JQuery to achieve this  functionality.

 <div id='status' style='color:#d41414;display:none;padding:5px'>  
 </div>  
 <div id='main-block' style='display:none'>  
      <div><h3>Documents</h3></div>  
      <div id="0">  
      </div>  
 </div>

 $(document).ready(function(){  
      //Enter the list name. If url is different, please update url variable too.  
      //Here code takes the current context and current website  
   var list = "TestFolders";  
   var url = list + "/";   
      createTree(url, 0, list);
