[Javascript] Add elements to form

[Rees, Mark (TWIi London)]

Hello

thanks for all the help, but I don't think I explained myself clearly
enough.

This is called in an "edit table" function (i.e. responds to an onclick
event after the whole page has loaded). So I have a table to which you can
for example add rows. Each cell has an individual form input containing its
value, formatting etc. What I was looking for was some way to do this
dynamically (since the cells are named with respect to their position in the
table, like row1column3 for example). So instead of having to write out
every time

<input type="hidden" name="R1C1" value="some text|bold">

I fancied document.form.R1C1.value='sometext|bold';

But it isn't having it. I presume this is because, as Hassan said, the form
elements collection is read only (presumably he means you can't create new
elements like this, because obviously you can change the value of existing
elements)?

Is that clearer?

Cheers

Mark

I've never had it fail if I call the form object after the closing form tag,
if you don't want to wait for the onload to fire. If you try to refer to the
form object before the closing tag, you get the "not an object" error.
