Discussion

The onKeyDown event fires when the user presses down a key on the keyboard when an element has focus. It is the first keyboard event to fire when the user presses a key. This event can be used to execute an Action Javascript, custom JavaScript, or server-side Xbasic to perform an action. For example, you may want to run some JavaScript when the user hits the Enter key.

if (event.keyCode == 13) {
   // Enter key has been pressed
}
