Remove the input box

Question

Hi how would i remove the Change Color input box without ruining all the other controls ?

Thanks

Code is below the bit i am concerned about is in the last lines

function PolygonCreator(map) {
    this.map = map;
    this.pen = new Pen(this.map);

It appears that button is only ever referenced inside that last function, Info. So I'd say it would be safe to comment out the 5 lines within that function that refer to it (as well as the 2 extra lines that form part of the click handler).

If you just want to hide this button from the user, you may just want to, literally, .hide() it after Info is called. This will be the least intrusive.

$('input[value="Change Color"]').hide();

Remove the input box
