How To Display Two Slideshows On The Same Page?

I'm using this slideshow as an example, which works perfectly fine. There are shared classes between each slideshow which means that when one finishes only then can the next one be

Solution 1:

I dont know if I should do this... But here goes Object Oriented Style of doing things...

1. Create single Class for ALL SLIDES
2. Create instances of each slide
3. Call functions for the instance you want.. The thing I edited in your html was the onclick calls for the Instances(or objects) and I wrapped both slides and dots in a single section div..

Now you have two sections of slides( slide + dots ) working independently..

let slide1 = newCreateSlide(0);
let slide2 = newCreateSlide(1);

functionCreateSlide(index) {
    this.slideContainer = document.getElementsByClassName("section")[index];
    this.slideIndex = 1;

    this.plusSlides = function(n) {
        this.showSlides(this.slideIndex += n);
    };
    this.currentSlide = function(n) {
        this.showSlides(this.slideIndex = n);
    };
    this.showSlides = function(n) {
        var i;
        var slides = this.slideContainer.getElementsByClassName("mySlides");
        var dots = this.slideContainer.getElementsByClassName("dot");
        if (n > slides.length) {
            this.slideIndex = 1
        }
        if (n < 1) {
            this.slideIndex = slides.length
        }
        for (i = 0; i < slides.length; i++) {
            slides[i].style.display = "none";
        }
        for (i = 0; i < dots.length; i++) {
            dots[i].className = dots[i].className.replace(" active", "");
        }
        slides[this.slideIndex - 1].style.display = "block";
        dots[this.slideIndex - 1].className += " active";
    }
    this.showSlides(1);
}
