[Resolved] Addressing Forms with Array Names using Javascript

twilson

This is mostly a JavaScript question, but it's caused because I am using array names in my INPUT fields for PHP's sake.

I am trying to change the value of a text field, from a separate window, by addressing the field in JavaScript. I know how to do this if the form field's name was say "Clipart", but my fields are named like "ARRAY[Clipart]". Normally you would address it like:

ParentWindow = window.opener;
ParentWindow.FormName.Clipart.value='$Data[Filename]';

BUT my problem is my field is an array name, and this does NOT work:

ParentWindow = window.opener;
ParentWindow.FormName.ARRAY[Clipart].value='$Data[Filename]';

The error is "Error: 'Clipart' is undefined". It doesn't work with single quote around Clipart or any way I've tried it (ARRAY.Clipart either).

Is there a different way to address this field?!

Thanks in advance!!!
Tom 🙂

Have you tried the "elements" array already?

In javascrip you can access a form element by its name or by its index on the "elements" array. For example if you have a form called form1 and you have any alement on it, lets say element1 you could call that contol as

document.form1.element1.wathever

document.form1.elements[0].whatever

any subsequent controls (elements) would have indexes 1,2,3,etc. in that array.

So, if you are having trouble accessing your form controls by name, why don't you try to access them by its index on that array?

Cool, I will try that. If a field is added or deleted though, it's going to most likely change it's index though right?

AtroZ

Yeah, any change in the order and/or number of controls in the form will change the index of the controls in the array. : - (

twilson

Yeah but it works like a charm for now 🙂 Thanks a lot. I will just have to keep an eye on it.

Peace,

Here's how I would do it:

oClipart = document.getElementsByName("ARRAY[Clipart]");

Unfortunately I haven't tested this in browsers other than IE.
