打动js自动播放幻灯片然后结束ID

Question

I have a script to auto-play Impress JS, but I don't know how to end the slideshow on a certain ID or how to stop looping the slideshow once it ends. Any help is appreciated.

<script>
  var impress = impress();
  impress.init();
  document.addEventListener('impress:stepenter', function(e){
    if (typeof timing !== 'undefined') clearInterval(timing);
    var duration = (e.target.getAttribute('data-transition-duration') ? e.target.getAttribute('data-transition-duration') : 2000); // use the set duration or fallback to 2000ms
    timing = setInterval(impress.next, duration);
  });
</script>

Answer 1

setInterval() returns an interval ID, which you can pass to clearInterval(). clearInterval is used to stop setInterval.

this should work:

    if (currentSlide === 'the_ID_where_you_want_to_end') {
    clearInterval(timing);
    } 

Answer 2

change

timing = setInterval(impress.next, duration);

with

if (e.target.id !== 'your_id') {
  timing = setInterval(impress.next, duration);  
}

and the presenter stops in your_id
