I'm sure I'm going to feel stupid after seeing the answer, but I keep running into prehistoric code around the web, which I'm not sure still applies. How do I change the value of a button (inside a form) using JavaScript?

Here's what I have right now:

function myFunc(form) {

    form.elements["submit-button"].value = "New<br>Text";

    "other stuff that actually works."

    return false;

}

followed by

<form onSubmit="return myFunc(this);">

    <button name="submit-button">Original<br>Text</button>

</form>

The "other stuff that actually works." actually works, so I'm sure the function is getting called and the button is getting found. I just can't seem to stick "New
Text" into the button!

Help much appreciated.
