轮播的第一张图片出现在我的页面中,但是按钮不起作用,图片也没有移动。我曾尝试使用不同类型的 Bootstrap 轮播,但无济于事。我看到一些建议将 jQuery 和 Bootstrap 链接添加到顶部的答案,所以我尝试了但也没有用。

最佳答案

Bootstrap 需要 JQuery 才能执行此类操作。您需要在 index.html 中添加 jquery 或将其添加到 angular-cli.jsonangular.json(取决于您的 Angular 版本):

方法 1(推荐):

首先运行这个命令来安装 JQuery 和 Bootstrap:

$ npm install jquery bootstrap --save

然后将这些行添加到 angular-cli.jsonangular.json(取决于您的 Angular 版本)

"styles": [
"styles.css",
"../node_modules/bootstrap/dist/css/bootstrap.min.css"
],
"scripts": [
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/popper.js/dist/popper.min.js",
"../node_modules/bootstrap/dist/js/bootstrap.min.js"
],

方法 2(不推荐):

在您的 index.html 中添加所需的脚本。不过要小心,因为每次重新加载页面时都会下载这些模板。
