Remove content and replace with text

[Cap123]

Hiya,

I have a form and I would like the form to be cleared and show a "Thank you!" sign.

<form action="Submitformcomplete.html" method="POST">
<h3>Signup for our Newsletter</h3>
<label>Email: </label>
<input type="text" name="$wgusername">
<input type="submit" name="$wgSignup" value="Sign up!">
</form>

What javascript do I need to add?

Add some div that wrapped your form and add an id attribute to form, let's say "signup-form". Then you can do it with jQuery:

$("<div>Thank you!</div>").insertAfter($("#signup-form"));
$("#signup-form").remove();

or with javascript:

var form = document.getElementById("signup-form");
form.parentNode.innerHTML = "<div>Thank you!</div>";
