Global variable unrecognized by window.ONLOAD?

[ruffy]

I code my global variables first,
then my window.onload function, like this:

var globvar = {
  oneTimeSwitch: "0",	
  kbinput: document.createElement("INPUT"),
  kbdivision: document.createElement("DIV"),
etc.
}

window.onload = function() {
  if (kbinput==undefined) alert("NO KBINPUT!!!!");
  setTriggers();
}

Why does this code generate this error:
"kbinput is not defined"?
Or, I suppose it's the same question,
why doesn't the if statement for undefined element
catch the problem?

Try this:

if (!window.kbinput) alert("NO KBINPUT!!!!");
