Error: uncaught exception: [Exception... "Node cannot be inserted at the specified point in the hierarchy"  code: "3" nsresult: "0x80530003 (NS_ERROR_DOM_HIERARCHY_REQUEST_ERR)"  location: "file.js Line: 34"]

the code that caused it is this:

if(isUndefined(option.childNodes[0])) {
                        var txtNode = document.createTextNode(data);
                  /* line 34 */      option.appendChild(txtNode);
                  }

What do you intend to do there?
Do you know the simple stright way to create Options?
Like this:

   var opt = document.forms[0].yourSelectName.options;
   opt[opt.length] = new Option("theOption Text", "theOptValue");

What is an option Node for you?
If it is a select option, then it is like this:

   var opt = document.forms[0].yourSelectName.options;
   if(opt[0].text==""){
      opt[0].text = "Option Text";
   }
