toggle()

There are probably tons of toggle functions in use and i admit that this one is nothing special but it is very handy for me. The history of ‘toggling’ basically comes down to showing and hiding off elements upon an event being fired. Here is my version of it

function toggle(objId) {
    var el = document.getElementById(objId);
    if ( el.style.display != 'none' ) {
        el.style.display = 'none';
    }
    else {
        el.style.display = '';
    }
}
