javascript - 为什么我的 bootstrap 3.7 轮播不工作？

Question

我一直在遵循有关如何实现 Bootstrap 的此功能的指南，但我一直无法弄清楚为什么它不起作用。我在标题中链接了所有 CDN，并链接了 Js 脚本。都是直接从bootstrap网站复制过来的。

<div id="productCarousel" class="carousel slide" data-ride="carousel">
    <ol class="carousel-indicators">
        <li data-target="#productCarousel" data-slide-to="0" class="active"></li>
        <li data-target="#productCarousel" data-slide-to="1"></li>
        <li data-target="#productCarousel" data-slide-to="2"></li>
        <li data-target="#productCarousel" data-slide-to="3"></li>
    </ol>

    <div class="carousel-inner" role="listbox">
        <div class="item active">
            <img src="../../static/images/city.jpg">
        </div>
        <div class="item">
            <img src="../../static/images/city.jpg">
        </div>
        <div class="item">
            <img src="../../static/images/city.jpg">
        </div>
        <div class="item">
            <img src="../../static/images/city.jpg">
        </div>
    </div>
    <a class="left carousel-control" href="#productCarousel" role="button" data-slide="prev">
        <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
        <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#productCarousel" role="button" data-slide="next">
        <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
        <span class="sr-only">Next</span>
    </a>
</div>

我检查了您的代码，一切正常。

检查您如何嵌入库。

1. Boostrap CSS
2. jQuery
3. 引导JS
