So, you place the items you want to render (such as images) in the "carousel-inner" div in a circular order, creating navigation for the items via "" It uses the custom data attribute "data-slide" to navigate to the previous and next items.

You must reference the jquery.js and bootstrap-carousel.js files in the HTML file where you want to create the carousel.

Use Javascript

You can use the JavaScript code below to create a carousel.

$('.carousel').carousel()

Copy after login

Here are the options available to you

interval: Specifies the waiting time for slide rotation, in milliseconds. The value is of type number and the default value is 5000. If false, the carousel will not automatically start looping.

pause: specifies that when the mouse stays in the slide area, the carousel will be paused, and when the mouse leaves, the carousel will be started. The value is of type string and the default value is 'hover'.

Here are the carousel methods you can use

.carousel(options): 初始化轮播组件，接受一个可选的 object 类型的 options 参数，并开始幻灯片循环。
$('.carousel').carousel({
 interval: 2000 // in milliseconds
})
.carousel('cycle'): 从左到右循环各帧。
$('.carousel').carousel('cycle');
.carousel('pause'): 停止轮播。
$('#myCarousel').hover(function () { 
 $(this).carousel('pause') 
}
.carousel(number): 将轮播定位到指定的帧上（帧下标以0开始，类似数组）。
$("#carousel_nav").click(function(){ 
var item = 4; 
$('#home_carousel').carousel(item); 
return false; 
});

.carousel('prev'): Move the carousel to the previous frame.

.carousel('next'): Move the carousel to the next frame.

Here are two events used to enhance the functionality of the carousel.

slide: This event is triggered immediately after the slide instance method is called.

slid: This event is triggered after all slides have played.
