Are there any rules when to include javascript in <head> or in <body> ?
For example,
<script type="text/javascript">
function reload(form)
{ var val=form.Chapter.options[form.Chapter.options.selectedIndex].value;
self.location='QueryForm.php?Chapter=' + val ;
}
</script>
Generally, script blocks outside of the head are meant to be used for
routines that run as the page is loading. For example, one might have
some JS that creates some block of HTML or something. Or one might have
a JS block at the very end of the page that is meant to run once the
page has (almost) completed loading. Why people do this, i'm not sure.
Personally, i think script blocks belong in the head. If you have some
function that needs to run at page load, there's the onload handler for
that.
In your case, it looks like that function could be placed pretty much
anywhere, as it can only be called once the page has loaded, anyway. Is
your problem that you can't change the head of the page (to include that
function) for some reason? In any case, go ahead and put it in the body.
