Question

I am trying to have an animation run only when the mouse is over an object. I can get one iteration of the animation and then have it set back to normal on mouse out. But I’d like the animation to loop on mouseover. How would I do it, using setInterval? I’m a little stuck.

Answer 1

It could be done like this:

$.fn.loopingAnimation = function(props, dur, eas)
{
    if (this.data('loop') == true)
    {
       this.animate( props, dur, eas, function() {
           if( $(this).data('loop') == true ) $(this).loopingAnimation(props, dur, eas);
       });
    }

    return this; // Don't break the chain
}

Now, you can do this:

$("div.animate").hover(function(){
     $(this).data('loop', true).stop().loopingAnimation({ left: "+10px"}, 300);
}, function(){
     $(this).data('loop', false);
     // Now our animation will stop after fully completing its last cycle
});

If you wanted the animation immediately stop, you could change the hoverOut line to read:

$(this).data('loop', false).stop();
