jQuery interval time delay and loading animation onclick event

Hello there,

Because the cff-calculation happens to quick I try to achieve delay of few seconds after pressing the (calculation) button as an onclick event. I tried it with this html and jquery code from this forum and it works:

<div class="delay"></div>

my_delay = 0;

my_interval = setInterval(function(){

    jQuery('.delay').html(my_delay);

    my_delay = my_delay - 1;

    if(my_delay<0){

        clearInterval(my_interval);

        jQuery('.delay').html('');

        EVALEQUATIONS();

    }

}, 3000);

However, during this delay (on click event) I try to achieve parallel to display a loading spinner or, if possible, to use the “display loading form animation” from cff to show/animate the user that loading is in progress. Is there a way?

Thank you guys and keep up all the good work!
