I'm trying to grab emails from URL and display.

2.     <script type="text/javascript">
3.         $(document).ready(function () {
4.            $("#submit").click(function () {
5.                 var curUrl = $("#url").val();
6.                 
7.                 function extractEmails(curUrl)
8.                 {
9.                     return curUrl.match(/([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z0-9._-]+)/gi);
10.                 }    
11.         
12.                 document.getElementById('result').innerHTML = curUrl;
13.                 
14.                 //Grab URL 
15.                 //Grab Emails RegEx
16.                 //Output Emails to screen with counter
17.                 //Save to database
18.                 $( "body" ).load( curURL ).text(extractEmails(curUrl).join('\n'));
19.                 
20.             });
21.         }); 
22.     </script>

Here are my codes

But it doesn't display the emails?

What are my mistakes here?

How to fix this?

thanks in advance.
