Variable lost with each function call - WHY?

[Keiron Waites]

This is my code:

<script language="JavaScript" type="text/javascript">
<!--
desc_switch = 0;
function description (desc,type) {
// onBlur
alert(desc_switch)
if (type == 3) {
desc_switch = 0;
description_area.innerHTML = desc;
}
// onFocus
else if (type == 2) {
desc_switch = 1;
description_area.innerHTML = desc;
}
// onMouseOut
else if ((type == 1) && (desc_switch == 0)) {
description_area.innerHTML = desc;
}
// onMouseOver
else {
description_area.innerHTML = desc;
desc_switch = 0;
}
}
// -->
</script>

<input type="text" name="name" maxlength="50" value="http://"
onMouseOver="description('Your',0);" onMouseOut="description('',1);"
onFocus="description('Your',2);" onBlur="description('',3);">

I would _really_ appreciate any help on this issue.

onFocus and onMouseOver are happening at the same time.
onBlur and onMouseOut are happening at the same time.

(in MSIE, test it in NN and you might get an other result).

So it is possible for a function to be called at exactly the same time? It's
not necessary for all function calls to go 1 by 1?

Thanks

I don't know. I'm sure that 'exactly' it shall not be.
I noticed that MSIE might 'forget' to handle the second event if it handled
the first one.
(else onmousedown and oncontextmenu would both be triggered on a right
click, that only happens in NN not in MSIE).

But why or how, I don't know. And maybe I'm just wrong.

It is not possible for events of different types to occur simultaneously
on IE browsers because they use a single global - event - property to
hold the references to the event objects. Each single event must be
fully processed (end of bubbling) before processing of the next event
can begin. Else the browser would have to put a great deal of effort
into keeping track of which event handlers were active and continually
swap the global event reference, and even then no two different event
objects could be referenced via the one global - event - property at the
same time.

What does description_area do? I see no reference to it. If I take the
description_area lines (which my browser fails on) out, the desc_switch
does not loose it's value.
