Laravel 5 js 被 app.js 阻塞

Question

我在home.blade.php 中使用了一个javascript，它扩展了layout/app.blade.php

@extend(layout.app)

当我在 home.blade.php 中扩展 javascript 时停止工作，所以我注释掉了

app.blade.php 中的<script src="{{ asset('js/app.js') }}" defer></script> 然后 javascript 开始工作。我不确定是什么问题，谁能帮我解决这个问题。

home.blade.php

@extends('layouts.app')
@section('content')
<div class="container">
   <div class="row justify-content-center">
      <div class="col-md-8">
         <div class="card">
            @if (Auth::user()->email=='admin@admin.com')
            <div class="card-header">Reports</div>
            <div class="card-body">
               <a href="view-reports">View Report</a><br>
               <a href="create-user">Create User</a>
            </div>
         </div>
         @else
         <div class="card-header">Report Form</div>
         <div class="card-body">

Answer 1

您的 app.blade.php 应如下所示：

<!DOCTYPE html>
<html lang="{{ app()->getLocale() }}">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1">

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

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

        <!-- Styles -->
        <link href="{{ asset('css/app.css') }}" rel="stylesheet">
    </head>
    <body>
        <div id="app">
            @yield('content')
        </div>

        <!-- Scripts -->
        <script src="{{ asset('js/app.js') }}"></script>
        @yield('javascript');
    </body>
</html>

以上是您的主要布局文件。如果您想在其他刀片文件中扩展它，您想使用该布局文件并添加内容或其他 javascript 功能。

为了更好地实现这一点，我们使用 @yield('javascript') 关键字来添加一个 javascript 文件或函数。

因此，扩展此刀片文件的其他刀片文件应如下所示：

@extends('layouts.app')

@section('content')
   // some content 
@endsection

@section('javascript')
   // your javascript
@endsection

首先您正在加载布局刀片文件，然后您可以将您的特定内容和 javascript 插入到您使用关键字 yield('xxx') 的每个部分中

查看您的源代码后：

您在 home.blade.php 中加载 jquery，这并不理想，如果您想加载它，您应该将它加载到您的主要刀片 php 文件中。但是如果你使用 laravel 默认的 app.js 文件，你实际上不需要加载它。默认的app.js 文件已经需要require('./bootstrap');。如果您没有更改，该文件已经包含 jquery。

try {
    window.$ = window.jQuery = require('jquery');

} catch (e) {}

所以检查您的app.js 是否需要引导文件并检查您的引导文件是否包含 jquery，如果是，则不需要在刀片文件中加载 jquery。

因此，您应该在主刀片中加载app.js 文件。在底部这样加载：

      ...
      <script src="{{ asset('js/app.js') }}"></script>
      @yield('javascript')
   </body>
</html>
