Hiding a button in Javascript

Question

In my latest program, there is a button that displays some input popup boxes when clicked. After these boxes go away, how do I hide the button?

Answer 1

//Your code to make the box goes here... call it box
box.id="foo";
//Your code to remove the box goes here
document.getElementById("foo").style.display="none";

of course if you are doing a lot of stuff like this, use jQuery
