How to jump to a specific item in Bootstrap's Carousel?
提问by Elijah Yang
Using Bootstrap's Carousel, I want to be able to click on a link and jump to a specific slide in the carousel. How do I do that? What jquery do I have to add?
使用 Bootstrap 的 Carousel，我希望能够单击链接并跳转到 carousel 中的特定幻灯片。我怎么做？我必须添加什么 jquery？
Here's my html (it doesn't work but gives you a sense of what I want to do):
这是我的 html（它不起作用，但让您了解我想要做什么）：
<a href="#panel">Panel</a>
<div id="myCarousel" class="carousel slide">
<div class="carousel-inner">
<div id="panel" class="item">
...
</div>
</div>
</div>

if your links are in the same order of the panels you can do something like:
如果您的链接与面板的顺序相同，您可以执行以下操作：
$('.link').on('click', function() {
$('#carousel').carousel($(this).index());
});
if you just have a single link just hardcode it:
如果您只有一个链接，只需对其进行硬编码：
var i = 2; //index of the panel
$('#link').on('click', function() {
$('#carousel').carousel(i);
});
from the docs:
从文档：
Methods:
carousel(options)
Initializes the carousel with an optional options object and starts cycling through items.
$('.carousel').carousel({
interval: 2000
})
.carousel('cycle')
Cycles through the carousel items from left to right.
.carousel('pause')
Stops the carousel from cycling through items.
.carousel(number)
Cycles the carousel to a particular frame (0 based, similar to an array).
.carousel('prev')
Cycles to the previous item.
.carousel('next')
Cycles to the next item.

for me the specified scripted method did not work, however based on another example I was able to make it work using data tags
对我来说，指定的脚本方法不起作用，但是基于另一个示例，我能够使用数据标签使其工作
<a data-target="#myCarousel" data-slide-to="0" href="#">First</a>
Please note that data-slide-toindex is based on 0, and this was tested on Bootstrap 4
请注意，data-slide-to索引基于 0，这是在 Bootstrap 4 上测试过的
