Angular5中的輪播

Question

我試圖使旋轉木馬幻燈片成角度。 我從（ https://getbootstrap.com/docs/4.0/examples/carousel/ ）中獲取了HTML和CSS。 但我不知道如何在網站中使用javascript。 app.component.html此html

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

輪播功能無效，下一個和上一個按鈕均無效。 任何幫助，我不知道為什么。

Answer 1

您沒有將引導程序正確添加到項目中。

通過npm安裝Bootstrap 4：

npm install --save bootstrap

將CSS添加到您的主HTML文件中：

@import "~bootstrap/dist/css/bootstrap.css"

您還需要添加jQuery，Popper.js和bootstrap.js

“腳本”：[“ ../node_modules/jquery/dist/jquery.js”，
“ ../node_modules/tether/dist/js/popper.js”，
“ ../node_modules/bootstrap/dist/js/bootstrap.js”]，

這也可能對您有幫助： https : //www.techiediaries.com/angular-bootstrap/
