Question

我正在尝试使用gijgo.js库中的treeview插件。一切在一个干净的示例项目中都可以正常工作- 库：jquery，bootstrap，gijgo（所有版本均与不工作的Laravel Project相同）已下载并手工包含在简单的index.html中；但是，该插件无法在基于Laravel框架的项目中运行，npm会将脚本正确编译到/public/js/app.js，浏览器控制台未报告任何错误，但页面看上去并不符合预期。我现在所做的：

我正在将Laravel 7.18与ui引导程序一起使用
使用npm install gijgo --save安装了gijgo.js

$(function() {
    $('#tree').tree({
            uiLibrary: 'bootstrap4',
            dataSource: data,
            primaryKey: 'id',
            imageUrlField: 'flagUrl'
    });
});

其余是导致布局和查看的标准请求处理 app.blade.php

<!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', 'treeView Example') }}</title>

    <!-- Fonts -->
    <link rel="dns-prefetch" href="//fonts.gstatic.com">
    <link href="https://fonts.googleapis.com/css?family=Nunito" rel="stylesheet">

    <!-- Styles -->
    <link href="{{ asset('css/app.css') }}" rel="stylesheet">
</head>
<body>
    <div id="app">
        <main class="py-4">
            @yield('content')
        </main>
    </div>
    
    <!-- Scripts -->
    <script src="https://kit.fontawesome.com/8e33cf2cfe.js" crossorigin="anonymous"></script>
    <script src="{{ asset('js/app.js') }}" defer></script>
</body>
</html>

tree.blade.php

@extends('layouts.app')

@section('content')
    <div class="container-fluid">
        <div id="tree"></div>
    </div>
@endsection

这是最终外观：

我怀疑这是在LaravelMix / webpack级别上进行编译的问题，因为我已经安装了该库而没有任何问题，浏览器控制台不会报告任何错误，但是脚本不起作用。也许这是在已编译的app.js中添加js库的顺序（但在这种情况下，我认为浏览器应提供“未定义的功能”）。

如何使其正常工作？

请精确提示，因为我是Laravel和所有这些前端（laravelmix，webpack）产品的初学者。感谢您的帮助

我会在标头而不是正文中加载Javascript依赖项/脚本。该主题在另一个线程上有一个有趣的答案：Where to insert JavaScript Libraries and CSS in my HTML code?

Answer 2

我错过了gijgo的CSS。

/resources/js/app.js 应该如下所示：

require('./bootstrap');
require('gijgo');
require('gijgo/css/gijgo.css');
