如何使用模态在同一页面上添加多个幻灯片？

时间：2018-08-29 09:04:30

标签： javascript html css modal-dialog slideshow

我在我的网站上创建了模态，并且试图在每个模态上添加不同的幻灯片。

使用此代码，我可以在每个模态上获得相同的幻灯片显示，但只添加了一些幻灯片。
我想添加不影响其他幻灯片的幻灯片。

我该怎么做？

HTML 

<div class="experience-list exper1">

JAVASCRIPT 

<!--MODAL-->

<script>
    var modalBtns = [...document.querySelectorAll(".overlay")];
    modalBtns.forEach(function (btn) {
        btn.onclick = function () {
            var modal = btn.getAttribute('data-modal');

            document.getElementById(modal).style.display = "block";
        }
    });

    var closeBtns = [...document.querySelectorAll(".close")];
    closeBtns.forEach(function (btn) {
        btn.onclick = function () {
            var modal = btn.closest('.modal');
            modal.style.display = "none";
        }
    });

    window.onclick = function (event) {
        if (event.target.className === "modal") {
            event.target.style.display = "none";
        }
    }
</script>

<!--SLIDESHOW-->
<script>
    var slideIndex = 1;
    showSlides(slideIndex);

    function plusSlides(n) {
        showSlides(slideIndex += n);
    }

    function currentSlide(n) {
        showSlides(slideIndex = n);
    }

    function showSlides(n) {
        var i;
        var slides = document.getElementsByClassName("mySlides");
        var dots = document.getElementsByClassName("dot");
        if (n > slides.length) { slideIndex = 1 }
        if (n < 1) { 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[slideIndex - 1].style.display = "block";
        dots[slideIndex - 1].className += " active";
    }
</script>

这里是我之前询问中的模态代码 模态

<!--MODAL-->
<script>
    var modalBtns = [...document.querySelectorAll(".overlay")];
    modalBtns.forEach(function (btn) {
        btn.onclick = function () {
            var modal = btn.getAttribute('data-modal');

            document.getElementById(modal).style.display = "block";
        }
    });

    var closeBtns = [...document.querySelectorAll(".close")];
    closeBtns.forEach(function (btn) {
        btn.onclick = function () {
            var modal = btn.closest('.modal');
            modal.style.display = "none";
        }
    });

    window.onclick = function (event) {
        if (event.target.className === "modal") {
            event.target.style.display = "none";
        }
    }
</script>

MODAL CSS

.modal {

    z-index: 1;
    /*padding-top: 100px;*/
    margin-top:100px;

您可以尝试类似=>

在javascript中：

var slideIndex = 1;
showSlides(slideIndex, "mySlides");
showSlides(slideIndex, "mySlides2");

    function plusSlides(n, slide) {
        showSlides(slideIndex += n, slide);
    }

    function currentSlide(n, slide) {
        showSlides(slideIndex = n, slide);
    }

function showSlides(n, slide ) {
        var i;
        var slides = document.getElementsByClassName(slide);
        var dots = document.getElementsByClassName("dot");
        if (n > slides.length) { slideIndex = 1 }
        if (n < 1) { 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[slideIndex - 1].style.display = "block";
        //dots[slideIndex - 1].className += " active";
    }

在html中：

<div class="experience-list exper1">
                <img src="" class="exp-image" />
                <button class="overlay" id="myBtn" data-modal="myModal">
