[jQuery] Re: calling functions between multiple document ready events

No, because if you say

<script type="text/javascript">
function MyFunctionThatAdds(x, y) {
..........
}
</script>

that *technically* attaches that function to the "window" object

so saying

var sum = MyFunctionThatAdds(3, 4);
alert(sum);

is the same as saying

var sum = window.MyFunctionThatAdds(3, 4);
alert(sum);

which is also the same as

window.sum = window.MyFunctionThatAdds(3, 4);
alert(window.sum);

Working example (all 3 will result in "7"):
http://paste.pocoo.org/show/119909/

So keeping that in mind, saying:

var MZ = {};
MZ.MyFunction = function(x, y) {
return x + 7;
}

i get the same results for:

alert(MZ.MyFunction(3,4));
and
alert(window.MZ.MyFunction(3,4));

as for "global functions are bad", i would agree with that if they are
used unnecessarily and in excess, but sometimes one wants common
functionality no matter where they are in the code
