javascript - 为什么 Laravel bootstrap 下拉菜单不起作用

问题描述

这是我的导航栏

<nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top">
    <a class="navbar-brand" href="/teashirt/public/">TeaShirt</a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>

    <div class="collapse navbar-collapse" id="navbarsExampleDefault">
        <ul class="navbar-nav mr-auto">
            <li class="nav-item active">
                <a class="nav-link" href="/teashirt/public/">Home <span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="/teashirt/public/design">Desing your Teashirt</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="/teashirt/public/about">About Us</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="/teashirt/public/contact">Contact</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="/teashirt/public/checkout">Checkout</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="/teashirt/public/cart" tabindex="-1" aria-disabled="true">Cart</a>
            </li>
            <li class="nav-item dropdown">
                <a class="nav-link dropdown-toggle" href="#" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Guest!</a>
                <div class="dropdown-menu" aria-labelledby="dropdown01">
                    <a class="dropdown-item" href="#">Profile</a>
                    <a class="dropdown-item" href="#">Another action</a>
                    <a class="dropdown-item" href="#">Logout</a>
                </div>
            </li>
        </ul>
        <form class="form-inline my-2 my-lg-0">
            <input class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search">
            <button class="btn btn-secondary my-2 my-sm-0" type="submit">Search</button>
        </form>
    </div>
</nav>

这是我的 bootsrap.js

window._ = require('lodash');

/**
 * We'll load jQuery and the Bootstrap jQuery plugin which provides support
 * for JavaScript based Bootstrap features such as modals and tabs. This
 * code may be modified to fit the specific needs of your application.
 */

try {
    window.Popper = require('popper.js').default;
    window.$ = window.jQuery = require('jquery');

    require('bootstrap');
} catch (e) {}

/**
 * We'll load the axios HTTP library which allows us to easily issue requests
 * to our Laravel back-end. This library automatically handles sending the
 * CSRF token as a header based on the value of the "XSRF" token cookie.
 */

window.axios = require('axios');

window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';

这是我的 app.js

require('./bootstrap');

Visual Studio Code 提供替换require为import，但它没有工作。

我试过 -popper upgrade -composer update

没有任何工作。一切都在导航栏上运行，但是当我单击下拉菜单时，它只会转到链接 /#。我已经在 IE 和 chrome 上试过了。结果相同
