jac*_*ils 4 javascript ruby-on-rails twitter-bootstrap webpacker
我正在使用 Railsbytes 脚本来安装 bootstrap 5 alpha；https://railsbytes.com/public/templates/VB0s5v。
但是，我无法使用任何工具提示和弹出窗口。甚至不确定我应该将脚本放在哪里，或者是否必须向其中添加任何内容才能启用它们。请有人好心并提供一些指导。多谢！

我怀疑我需要根据https://v5.getbootstrap.com添加某个地方的 js 示例：
var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
return new bootstrap.Tooltip(tooltipTriggerEl)
})
我也为此苦苦挣扎，但现在已经让他们工作了。这是我让 Bootstrap5 与 Rails6 配合使用的工作流程。
yarn add bootstrap@nextyarn add @popperjs/coreapp/javascript/stylesheets/application.scss，我将在其中添加自定义 css# app/javascript/stylesheets/application.scss
@import "bootstrap"
<%= stylesheet_pack_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>。pack_tag 表明这将由 webpacker 处理。布局文件将如下所示：# app/views/layouts/application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Hello World</title>
<meta name="viewport" content="width=device-width,initial-scale=1">
<%= csrf_meta_tags %>
<%= csp_meta_tag %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
<%= stylesheet_pack_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
</head>
<body>
<%= yield %>
</body>
</html>
# app/javascript/packs/application.js
import * as bootstrap from 'bootstrap'
import "../stylesheets/application"
document.addEventListener("DOMContentLoaded", function(event) {
var popoverTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="popover"]'))
var popoverList = popoverTriggerList.map(function (popoverTriggerEl) {
return new bootstrap.Popover(popoverTriggerEl)
})
var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'))
var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
return new bootstrap.Tooltip(tooltipTriggerEl)
})
});
作为测试，我将以下 Bootsrap 组件添加到我的主页（或任何要测试的页面）：
# index.html.erb
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">

</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="top" title="Tooltip on top">
