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

    in the head section, I have this code:

    <script LANGUAGE="javas cript">
    <!--
    document.body.o nload=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.o nload
      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.o nload=hiThere() ;
      you probably want
      document.body.o nload=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
