jQuery Event Keypress: Which key was pressed?

Actually this is better:

 var code = e.keyCode || e.which;
 if(code == 13) { //Enter keycode
   //Do something
 }

Try this

$('#searchbox input').bind('keypress', function(e) {
    if(e.keyCode==13){
        // Enter pressed... do anything here...
    }
});
