trying to create one function that will take a form name/id and a feild name/id and value.
it then sets the hidden feild tot he value and submits the form.

this completely lack of names is for modularity.
and also because i will be duplicating it and making a modified version that takes several hidden feild/value combinations

what i have right onw is the first function located @ http://24.91.157.113/findyourdesire/zctest.js
and as you can see in the test script located @ http://24.91.157.113/findyourdesire/zdtest.php
it's clearly not working. what i'm wondering is how to get it working and why it's not, so i wont make the mistake again

POSIX. because a stable os that doesn't have memory leaks and isn't buggy is always good.

ok. here's the function:

function selsub(form,hfld,hval){ // submit a form and set a hidden variable
  document.getElementById(hfld).value=hval;
  document.getElementById(form).submit();
  return true;
}

'
here's the simple page made to test it:

<html>
    <title>test page</title>
    <style type="text/css">
      <!--
      @import url(textStyle.css);
      @import url(zatest.css);
      -->
    </style>
    &lt;script src="zctest.js" type="text/javascript"&gt;
      <!--
      -->
    &lt;/script&gt;
  </head>
  <body>
<form action="/findyourdesire/zdtest.php" id="tst" name="tst"><input type="hidden" name="test" />
<br /><a href="#" onclick="selsub('tst','test','clicky clicky');">click here to submit</a>
<br /><a href="#" onclick="selsub('tst','test','you clicked the wrong one');">click here to submit</a>

</form>
  </body>
</html>

'as you can see it's quite simple i'm trying to get the hidden feild to be set so i'll seee it in the location bar. at that point i can make 3 pages become html 4.01 compliant that i can't keep compliant any other way

You're trying to use getElementById(hfld) for an object that doesn't have an id set?

gah! i think you might be right
unfortunately i'm so used to html 3.0 since that's what i first learned and then i really never used it until 4.01 that i'm still not used to ids...

heh, happens.

As an aside: getElementById is not the only valid selector. Sometimes others like document.forms[i].elements(index) might be more useful.
