Hi,
Simple question here. How do you use a variable inside another variable name?

Example:

function enableMe(form,button) {
document.form.button.disabled=false;
}

In this example I would be passing a form name (form), and a button name (button) to the function as an argument. How do you insert those 2 variables into the "document.form.button.disabled=false;" statement? The way it is obviously does not work, because the function looks for a form named "form" and a button named "button" and they do not exist.

If I were to try something like:
"document.[form].[button].disabled=false;"

There is a JScript error about "Object Expected". I'm thinking it's because the [form] and [button] are not evaluated, but I don't know why.

Any advice/help is great!
Many thanks
Maniax

Good guess, just remove the dots like this:
"document[form][button].disabled=false;"

you are giving values to them right?

such as:
onClick('something', 'something')
onMouseOver('something', 'something')
onChange('something', 'something')

otherwise it will come back with an error

Hmm been awhile since I've had any problems but all the sudden the method posted above doesn't seem to work on a (what looks like simple) function. Keep getting errors saying I'm missing a ";"...

Code:

function Reset(field) {
	document.category[field]style.backgroundColor='FFFFFF';
}

And the call to the function:

Code:

onKeyUp="Reset('title')"

Something I'm missing here?

You've forgotten a . not a ; that is just what the Javascript engine thinks...

Code:

function Reset(field) {
	document.category[field].style.backgroundColor='FFFFFF';
}
