Not able to get this to work.  this.id and $(this).attr("id") each return undefined.
How can I make this work so that I return the id of the field that is being clicked?

Sample A:  Desired solution
$(document).keypress(function(event){
 
      var keycode = (event.keyCode ? event.keyCode : event.which);
      if(keycode == '13'){
            alert('You pressed a "enter" key in somewhere ' + this.id);      
      }
 
});            

Sample B more desired solution
$('.myclass').keypress(function(event){
 
      var keycode = (event.keyCode ? event.keyCode : event.which);
      if(keycode == '13'){
            alert('You pressed a "enter" key in somewhere ' + this.id);      
      }
 
});

http://api.jquery.com/event.which/
the event.which property normalizes event.keyCode and event.charCode
check this : http://jsfiddle.net/UbG4W/
$('.myclass').keypress(function(event){
      if(event.which == '13'){
            alert('You pressed a "enter" key in somewhere ' + this.id);      
      }
});
