javascript - 如何使用 popper.js 和 bootstrap 初始化工具提示

问题描述

我正在使用引导工具提示，如 @ https://getbootstrap.com/docs/4.3/components/tooltips/

我已成功创建工具提示，但工具提示显示为未格式化。我相信这是因为工具提示没有被初始化。我添加了如下页面所示的代码。在页面的不同位置也尝试了初始化代码。

如引导页面所示，未选择工具提示样式。

解决方案

我可以通过在 head 中添加引导导入来解决此问题

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="description" content="">
    <meta name="author" content="Martious">
    <link rel="shortcut icon" href="/static/favicon.ico">
    <title>Start Your Data Science Journey Here...</title>
    <!-- Bootstrap Core CSS -->
    <link href="/static/css/bootstrap.min.css" rel="stylesheet">
    <!-- Additional Custom Style CSS -->
    <link href="/static/css/starter-template.css" rel="stylesheet">
    <link href="/static/open-iconic/font/css/open-iconic-bootstrap.css" rel="stylesheet">

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>

</head>

这不是根据引导程序建议（https://getbootstrap.com/docs/4.3/getting-started/introduction/#starter-template），但它有效。

该修复来自@ https://www.w3schools.com/bootstrap4/bootstrap_tooltip.asp描述的代码
