Problems with keydown-Event when pushing ESC

Problems with keydown-Event when pushing ESC

Hello,

I want to send an Ajax-Request, when the Esc-key is pushed. (keycode == 27)

The code is shown below:
  1.   $j(this).keydown(function(event)
      {
        switch(event.keyCode)
        {
          case 27:
            if(wp_active() && ready_to_submit)
            {
              $j(".wp_cancel").click();
            }
          break;








  2. ...
The strange point is: The request gets fired and canceled immediately. When i try the same thing with any other key, it works fine. (request is not being canceled) Any idea whats the problem?

Best Regards
