Help for JS

Hello there, fellow maplers and programmers. Hopefully some of you guys may help me with this simple piece of code:

Code:

function disable_enable(){
    document.form.text.disabled= !document.form.text.disabled;
}

What I want to do, is to be able to use this function on several elements. A simple example of what I want the function to do is this:

Code:

function disable_enable(id){
    document.form.id.disabled= !document.form.id.disabled;
}

Where id is a thing you're allowed to change as you wish. Understand what I mean?

So now the issue is that I don't know how to do this in javascript, as I'm no good with it. Anyone that want to help me with this? Thanks!

document.getElementById(id) gets the element with the specified id. Store it in a variable (say "foo") and you can just do

Code:

foo.disabled = !foo.disabled;

Ah, thanks. I myself used this, as I name all the input-data in the forms. Seems to work fine in this way:

Code:

function enable_disable(str){
    var x = document.getElementsByName(str)[0];
    x.disabled = !x.disabled;
}
