The problem is that the API hooks for request and cancel full screen are different; it is not a toggle on it's own.

You need to make some minor modifications:

JavaScript

var fullScreen = false;
function toggleFullScreen() {
            if (element.requestFullScreen) {
                if(fullScreen){
                   element.CancelFullScreen();
                   fullScreen = false;}
                else{
                   element.requestFullScreen();
                   fullScreen = true;
                }
            } else if (element.webkitRequestFullScreen) {
                if(fullScreen){
                   element.webkitCancelFullScreen();
                   fullScreen = false;
                }
                else{
                   element.webkitRequestFullScreen();
                   fullScreen = true;
                }
            } else if (element.mozRequestFullScreen) {
                if(fullScreen){
                   element.mozCancelFullScreen();
                   fulLscreen = false;
                }
                else{
                   element.mozRequestFullScreen();
                   fullScreen = true; 
                }
            }
        }
