请考虑我正在尝试集成的以下代码行：

第一部分：

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script> 
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />

第二部分：

<script> var processFinish = false; 
         var tf_dialog_count; 
         var tf_dialog_counter;
         function verifyMe(u,key,fname,status) 
         { 

         if(processFinish) 
         { 
             tf_dialog_count = 0; 
             return true; } 
         else { 
             if(typeof status === 'undefined') 
             { $("body").append("<div id='tf_dialog'><p></p></div>");
             var unameVal = $("#"+u).val(); 
             var surl = 'http://someurl.com/username/filename.cfc?method=generateToken&uname='+unameVal+'&key='+key+'&callback=?'; 
             var retRes = false; 
             $.getJSON(surl, function(data) 
             { 
                 if(parseInt(data.RESULT) == 1) 
                   { $("#tf_dialog").html(data.MSG); 
                   $("#tf_dialog").append("<br>Time Remaining <span id='tf_dialog_counter'></span> secs"); 
                   $("#tf_dialog").append("<br><span id='tf_dialog_waiting'>Waiting</span>"); 
                   $("#tf_dialog").dialog({ height: 200 }); 
                   tf_dialog_count = 20; 
                   tf_dialog_counter=setInterval(timer, 1000); 
                   setInterval(function() { verifyMe(unameVal,key,fname,'checkStatus'); },7000); 
                   return false; } 
                   else { 
                   alert(data.MSG); 
                   return false; 
                        } }) } 
                   else { if (tf_dialog_count > 0) 
                   { var surl = 'http://someurl.com/username/filename.cfc?method=getStatus&uname='+u+'&key='+key+'&callback=?';
                    $.getJSON(surl, function(data) { $("#tf_dialog_waiting").animate({fontSize:"22px"},3500,function(){ $(this).animate({fontSize:"10px"},3500); });
                     if(parseInt(data.RESULT) == 1)
                      { processFinish = true; $('#'+fname).submit(); } 
                      else { return false; } }); 
                      } } return false; } } 
                      function timer() 
                      { tf_dialog_count=tf_dialog_count-1; 
                      if (tf_dialog_count <= 0) 
                      { clearInterval(tf_dialog_counter); processFinish = false; 
                      $("#tf_dialog").html(""); 
                      $("#tf_dialog").dialog("destroy"); 
                      $("#tf_dialog").remove(); 
                      alert("Time out. Please try again!!"); 
                      } $('#tf_dialog_counter').html(tf_dialog_count); 
                      } </script>

第三部分：

我需要为onSubmit属性添加以下代码：

return verifyMe('<username_textbox_id>','<key>','<form_id>')

我创建了一个登录表单（ColdFusion）并尝试运行代码，但想知道我的代码有什么问题。如果我输入错误的变量，请告诉我。

这是迄今为止我在 Dreamweaver 中使用的全部代码：
