Laravel错误: jQuery.easing不是函数

Question

我有一个laravel项目，在其中，我想使用jQuery UI平滑过渡和效果。我将jquery-ui.js添加到public/js文件夹中。与我当前的jQuery文件相同，该文件按预期工作。

我在刀片模板中导入了javascript文件，如下所示：

<!doctype html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <!-- CSRF Token -->
    <meta name="csrf-token" content="{{ csrf_token() }}">

    <title>{{ config('app.name', 'Laravel') }}</title>

    <!-- Scripts -->

                    {{ config('app.name', 'Laravel') }}
                </a>
                <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="{{ __('Toggle navigation') }}">
                    <span class="navbar-toggler-icon"></span>
                </button>

                <div class="collapse navbar-collapse" id="navbarSupportedContent">
                    <!-- Left Side Of Navbar -->
                    <ul class="navbar-nav mr-auto">

                            </li>
                            @if (Route::has('register'))
                                <li class="nav-item">
                                    <a class="nav-link" href="{{ route('register') }}">{{ __('Register') }}</a>
                                </li>
                            @endif
                        @else
                            <li class="nav-item dropdown">
                                <a id="navbarDropdown" class="nav-link dropdown-toggle" href="#" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" v-pre>
                                    {{ Auth::user()->name }} <span class="caret"></span>
                                </a>

                                <div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdown">
                                    <a class="dropdown-item" href="{{ route('logout') }}"
                                       onclick="event.preventDefault();
                                                     document.getElementById('logout-form').submit();">
                                        {{ __('Logout') }}
                                    </a>

                                    <form id="logout-form" action="{{ route('logout') }}" method="POST" style="display: none;">
                                        @csrf
                                    </form>
                                </div>
                            </li>
                        @endguest
                    </ul>
                </div>
            </div>
        </nav>

        <main class="py-4">
            @yield('content')
        </main>
    </div>


    <script type="text/javascript" src="{{ asset('js/jquery-3.4.1.min.js') }}"></script>
    <script type="text/javascript" src="{{ asset('js/jquery-ui.js') }}"></script>
    <script type="text/javascript" src="{{ asset('js/main.js') }}"></script>
    <script type="text/javascript" src="{{ asset('js/app.js') }}"></script>
</body>
</html>

当我试图调用按钮上的切换函数时，我会得到以下错误：

app.js:14040 Uncaught : jQuery.easingthis.easing不是一个函数

虽然常规的jQuery工作正常，但jQuery UI不工作。

Main.js

$(document).ready(function() {

    $('#slide-next').on('click', function() {
        $('.register-form-user').toggle("slide", { direction: "left" }, 1000);
    });
});

我所有的路都是正确的。在下载jQuery UI文件时，我确保选择了所有可用的选项，包括放松。

是什么导致了这个错误？

Bootstrap.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';

/**
 * Echo exposes an expressive API for subscribing to channels and listening
 * for events that are broadcast by Laravel. Echo and event broadcasting
 * allows your team to easily build robust real-time web applications.
 */

// import Echo from 'laravel-echo';

// window.Pusher = require('pusher-js');

// window.Echo = new Echo({
//     broadcaster: 'pusher',
//     key: process.env.MIX_PUSHER_APP_KEY,
//     cluster: process.env.MIX_PUSHER_APP_CLUSTER,
//     encrypted: true
// });

jQuery已经包含在来自boostrap.js文件的app.js包中。在html中对app.js的最后一次调用覆盖了之前的jquery实例，使其在jQuery UI之后加载。jQuery必须在jquery之前加载。

改变这个

<script type="text/javascript" src="{{ asset('js/jquery-3.4.1.min.js') }}"></script>
<script type="text/javascript" src="{{ asset('js/jquery-ui.js') }}"></script>
<script type="text/javascript" src="{{ asset('js/main.js') }}"></script>
<script type="text/javascript" src="{{ asset('js/app.js') }}"></script>

到这个

<script type="text/javascript" src="{{ asset('js/app.js') }}"></script>
<script type="text/javascript" src="{{ asset('js/jquery-ui.js') }}"></script>
<script type="text/javascript" src="{{ asset('js/main.js') }}"></script>

并从<head>部分删除延迟脚本标记
