This is actually a bit OT for this discussion group since the question
is just about how javascript works, but hopefully nobody minds if I
take a stab at explaining. :)
If you have a <script></script> it will be executed as soon as the
document has loaded to that point. So, if you have:
<script>
function foo() {
...
}
</script>
of course nothing will happen except that foo() will now be available
to other scripts. On the other hand, if you have, say, some global
variable, bar, then:
<script>
bar++;
</script>
bar will be immediately incremented as soon as that bit of code is
loaded. Thus, if you add the following anywhere inside your <html></
html> tag:
<script>
window.onload = ...
window.onunload = ...
</script>
then the onload and onunload handlers will be set and called as
appropriate. Of course replace "..." with references to your uniquely
named functions.
Hopefully that was clear enough, and hopefully my wording wasn't so
incorrect as to be useless. ;)
