Question

I have a variable of unknown value, it will be an integer. For this sake, lets say var a = 3;

I have a function that is called continuously:

var a = 3;
function anim() {
        left = parseInt(galleryInner.css('left'), 10);   
        if(Math.abs(left) >= (galleryItem.length * galleryItem.width())){
            galleryInner.css('left', 0);
        }
        galleryInner.animate({left: '-=20' }, 200, anim);

        that.appendEnd();
}

I’d like run this.appendEnd() only every 3 times, because a === 3.

How can I do this?

Answer 1

Instantiate a counter variable that increments every time anim() is called. When

counter % a === 0

Then you run this.appendEnd()
