View Full Version : form field copying

Mar 19th, 2003, 04:47 AM

I have two form fields in a form named "myform".

One is:

<input type="text" name="thing[1]" value="Blaa">

and the other is:

<input type="text" name="stuff">

How do I copy the value of the first field into the second field.

I've tried the following:

document.myform.stuff.value = document.myform.thing[1].value;

But it gives the error:

Error: 'document.myform.thing.1' is null or not an object

The reason I need that "[1]" in the name of the first field is because I actually have many fields, all of them named "thing" but with different numbers (ie: thing[2], thing[3], etc...) This is so they get passed into my PHP script as an array.

Thanks for any help you can give,

you can't use the dot syntax if the fieldname contains special characters. you can use the elements array instead.

document.myform.stuff.value = document.myform.elements["thing[1]"].value;

That worked.
