Using the getElementById it can be done easily, one example below:

HTML Code:

<html> <head> <script type="text/javascript">
      function referenceMe( fieldID )
      {
        var field = document.getElementById( fieldID );
        alert( "The value of the field " + fieldID + " is: " + field.value );
      }
    </script> </head> <body> <input type="text" id="test@code" onkeyup="javascript:referenceMe( this.id )"> </body> </html>

Or if you wanted to pass the field id in the function itself, you'd just surround it with single quotes, eg:
onkeyup="javascript:referenceMe( 'test@code' )"

Sorry, this wasn't all too quick.
