[英]How to slide bootstrap carousel manually using JavaScript
我已经阅读了整个引导传送带文档，但是找不到手动滑动引导传送带的方法。 任何帮助表示赞赏。

数据间隔设置为false的代码：

编辑：
我的页面上有几个标签。 基于选定的选项卡，我希望特定的幻灯片可见。 然后用户可以使用<或>。 在其他幻灯片中移动。
它已经在那说了。 请设定
interval: false
它将停止自动循环。此后，如果您想手动转到任何幻灯片或所需的任何代码，都可以执行此操作。
$('#myCarousel').on('slide.bs.carousel', function () {
$('#myCarousel').carousel('what slide I want')
})
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"; }
