Hi, this is a automatic slideshow script. var slideIndex = 0; function showSlides(n) { 'use strict'; var i, slides = document.getElementsByClassName("slideshow"), dots = document.getElementsByClassName("dot"); for (i = 0; i < slides.length; i++) { slides.style.display = "none"; } slideIndex++; if(slideIndex > slides.length) {slideIndex = 1; } if(slideIndex < 0) { slideIndex = slides.length} for (i = 0; i < dots.length; i++) { dots.className = dots.className.replace(" active", ""); } slides[slideIndex - 1].style.display = "block"; dots[slideIndex - 1].className += " active"; var timeHandler = setTimeout(showSlides,5000); } showSlides(slideIndex); function plusSlides(n) { 'use strict'; showSlides(slideIndex += n-1); } function currentSlide(n) { 'use strict'; showSlides(slideIndex = n-1); } Now I want to reset the time when the dots variable is clicked. And set the timeout 5s again. I tried to clear the timeout and invoke the setTimeout var again. But it didn't help. Can you guys please help me to reset the time? Thank you in advance.
