Question

我正在使用Visual Studio提供的jquery和Bootstrap。 Bootstrap v3.3.7，jQuery JavaScript Library v2.2.0

虽然我已经掌握了一切，但似乎脚本没有激活旋转木马是一个问题。这些脚本来自asp net core应用程序的Layout页面。我在这里只转录了html中的输出。

Html代码：

<!--Carousel Wrapper-->
        <div id="myCarousel" class="carousel" data-ride="carousel">
            <!--Indicators-->
            <ol class="carousel-indicators">
                <li data-target="#" data-slide-to="0" class="active"></li>
                <li data-target="#" data-slide-to="1"></li>
                <li data-target="#" data-slide-to="2"></li>
            </ol>
            <!--/.Indicators-->
            <!--Slides-->
            <div class="carousel-inner" role="listbox">
                <!--First slide-->
                <div class="carousel-item active">
                    <img class="d-block w-100" src="https://mdbootstrap.com/img/Photos/Slides/img%20(130).jpg" alt="First slide">
                </div>
                <!--/First slide-->
                <!--Second slide-->
                <div class="carousel-item">
                    <img class="d-block w-100" src="https://mdbootstrap.com/img/Photos/Slides/img%20(129).jpg" alt="Second slide">
                </div>
                <!--/Second slide-->
                <!--Third slide-->
                <div class="carousel-item">
                    <img class="d-block w-100" src="https://mdbootstrap.com/img/Photos/Slides/img%20(70).jpg" alt="Third slide">
                </div>
                <!--/Third slide-->
            </div>
            <!--/.Slides-->
            <!--Controls-->
            <a class="carousel-control-prev" href="#" role="button" data-slide="prev">
                <span class="carousel-control-prev-icon" aria-hidden="true"></span>
                <span class="sr-only">Previous</span>
            </a>
            <a class="carousel-control-next" href="#" role="button" data-slide="next">
                <span class="carousel-control-next-icon" aria-hidden="true"></span>
                <span class="sr-only">Next</span>
            </a>
            <!--/.Controls-->
        </div>
        <!--/.Carousel Wrapper-->

页面末尾的脚本：

    <script src="/lib/jquery/dist/jquery.js"></script>
        <script src="/lib/bootstrap/dist/js/bootstrap.js"></script>



    <script src="/js/site.js"></script>


    <script>
        $(document).ready(function () {

            $('#myCarousel').carousel();

        });
    </script>
</body>
</html>
