jQuery “blinking highlight” effect on div?

Answer 1

If you don't want the overhead of jQuery UI, I recently wrote a recursive solution using .animate(). You can customize the delays and colors as you need.

function doBlink(id, count) {
    $(id).animate({ backgroundColor: "#fee3ea" }, {
        duration: 100, 
        complete: function() {

            // reset
            $(id).delay(100).animate({ backgroundColor: "#ffffff" }, {
                duration: 100,
                complete: function() {

                    // maybe call next round
                    if(count > 1) {
                        doBlink(id, --count);
                    }
                }
            });

        }
    });
}

Of course you'll need the color plugin to get backgroundColor to work with .animate(). https://github.com/jquery/jquery-color

And to provide a bit of context this is how I called it. I needed to scroll the page to my target div and then blink it.

$(window).load(function(){
    $('html,body').animate({
        scrollTop: $(scrollToId).offset().top - 50
    }, {
        duration: 400,
        complete: function() { doBlink(scrollToId, 5); }
    });
});
