JScript passing value

[IS]

Hi folks,

Any ideas why this doesn't work?

<SCRIPT LANGUAGE="JavaS cript">
<!--
f = document.forms[1];
e = f.elements;
str = new String(e[0].value);
len = document.forms['testform'].d.options.leng th;
document.forms['testform'].d.options[len] = new Option(str, '1');
</script>

Basicaly, I am trying to fill my combo box on a HTML page (SELECT OPTION
field) manually, but the vallue I get every time is 'null', i.e. empty
string.
*Suspected error in the red line, since if I put in the last line "....new
Option('some',' 1');" it works.

I must have made some ridiculous error I can't see, so plz be free to make
fun of me :))

Thanks in advance.
IS
btw. if I put up an event at the Text field (onChange) the values can be transfered to my combo box trought a function call, but are lost as soon as I press Submit button I have next to my Text field.

You only have one form on the page?

<script type="text/javascript">

This gets the second form. I hope that was what you wanted.
Otherwise, forms[0].
[color=blue]
> e = f.elements;
> str = new String(e[0].value);[/color]
I hope this element has a value and is either a text input or text area.
You didn't check.

> len = document.forms['testform'].d.options.leng th;[/color]
I hope the select is named d.
[color=blue]
> document.forms['testform'].d.options[len] = new Option(str, '1');

No "Red lines" for people with plain text mail readers.

You maybe better off using names, not numbers. Otherwise, if you move
elements around, you have to change all the code! I suspect the problem
is with e[0].value.
Try e["elementnam e"].value

Oh, and submitting "loses" values - the form blanks out once the page
location changes.
