Unable to access javascript function on <body> from <head>

Hello everyone. Hope ya'll had a nice New Year. Anyway, my question
is why won't this work? I must be doing something dumb . . . here is
the code:

in the body tag, I have this code (just to test):

<script LANGUAGE="javascript">
<!--
function hiThere() {
alert("hi");
return true;
}
//-->
</script>

in the head section, I have this code:

<script LANGUAGE="javascript">
<!--
document.body.onload=hiThere();
//-->
</script>

By the way, I know someone will comment, by "does not work, I mean on
the load of the page, the alert is not displayed, nor are any errors.
Thanks for any help you can offer.

Have a great day!
Ryan

You should get errors, with script in the head
document.body
should be null so
document.body.onload
alone should trow an error.
And trying to call
hiThere()
in a script block before the script block that defines the function
hiThere should also cause an error.
If you want to use a function in a script block make sure it is defined
inside the same script block or in an earlier script block.

As for
document.body.onload=hiThere();
you probably want
document.body.onload=hiThere;
but for most browsers you need
window.onload = hiThere
anyway (of course that works only if the function is already defined).

Thanks for the reply Martin! Duh, I don't know what I was thinking.

What I am trying to do is render a javascript block in asp . . . but
that is a post for another group. I was thinking I could test what I
was trying to accomplish this way.

Anyway, thanks again!
Ryan
