Web: Masking The SPACEBAR and enter responses of a BUTTON element

The TAB key toggles the focus between the various elements, and then the SPACEBAR and enter keys on the keyboard trigger the Click event, and I don't want this effect here.

So I need to block these two keys.

function KeyUp (e) {  var currkey = 0;  E = e | | event;  currkey=e.keycode| | e.which| | e.charcode;//support IE, FF  if (Currkey = = 32) {//SPACEBAR     Eventchangemode ();//Use this button to do something else
Shield pass     E.preventdefault? E.preventdefault (): (E.returnvalue = false);}  } Document.onkeyup = KeyUp; Register the keys on the document.
