Question

您好，我是laravel 7的新用户。我想在刀片文件中使用jquery。如果我创建了一个刀片文件，并在其顶部提到了所有头部和主体，然后在其中提供了jquery的链接，那么它将正常工作。但就我而言，我创建了一个nav.blade.php文件，在其中放置了所有导航头和正文代码。然后我创建另一个文件并在该文件的顶部扩展导航文件，但在这种情况下，jQuery无法正常工作

nav.blade.php代码

<html>
<head>
    <meta charset="utf-8">

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

    <!-- Scripts -->
    <script src="{{ asset('js/app.js') }}" defer></script>

    <!-- Styles -->
    <link href="{{ asset('css/app.css') }}" rel="stylesheet"> 
 <!-- the below i use for jquery -->
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>
<body>
<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="#">Navbar</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">
        <ul class="navbar-nav mr-auto">
            <li class="nav-item active">
                <a class="nav-link" href="{{'addcategory'}}">Add Catgory <span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="{{'showcategory'}}">show Category</a>
            </li>
            <li class="nav-item dropdown">
                <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                    Manage Products
                </a>
                <div class="dropdown-menu" aria-labelledby="navbarDropdown">
                    <a class="dropdown-item" href="{{'
                    addproducts'}}">Add Products</a>
                    <a class="dropdown-item" href="#">Another action</a>
                    <div class="dropdown-divider"></div>
                    <a class="dropdown-item" href="#">Something else here</a>
                </div>
            </li>
            <li class="nav-item">
                <a class="nav-link disabled" href="#">Disabled</a>
            </li>
        </ul>
        <form class="form-inline my-2 my-lg-0">
            <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
            <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
        </form>
    </div>
</nav>
@yield('content')
</body>
</html>

showcategories.blade.php文件这是我要使用jquery的文件，并且在此文件中扩展了内部文件

@extends('layouts.nav')
@section('content')
    <table class="table">
        <thead>
        <tr>

            <th scope="col">id</th>
            <th scope="col">name</th>
            <th scope="col">Delete</th>
            <th scope="col">Update</th>
            <th scope="col">Get Products</th>
        </tr>
        </thead>
        <tbody>
        @foreach($categories as $cat)
        <tr>

            <td>{{$cat->id}}</td>
            <td>{{$cat->name}}</td>
            <td><a class="btn btn-danger" href="{{url('delete',$cat->id)}}">Delete</a> </td>
            <td><a class="btn btn-danger" href="{{url('update',$cat->id)}}">update</a> </td>
            <td><a class="btn btn-danger" href="{{url('getproductjoin',$cat->id)}}">getproducts</a> </td>

        </tr>

        @endforeach
        </tbody>
    </table>
    <button id="hello" class="btn btn-danger">hello</button>

    @endsection
@section('script')
<script >
    $(document).ready(function() {
        $("#hello").click(function () {
            alert("hello there");
        })
    });
</script>
    @endsection

在此文件上，jquery无法正常工作。请帮助我

Answer 1

您需要遵循Laravel语法和标准。您可以为应用程序创建标准布局文件。即main.blade.php，在该文件中，您可以根据需要设置@yield所需的内容。例如，您的main.blade.php可能像这样：

<html>
<head>
    <meta charset="utf-8">

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

    <!-- Scripts -->
    <script src="{{ asset('js/app.js') }}" defer></script>

    <!-- Styles -->
    <link href="{{ asset('css/app.css') }}" rel="stylesheet"> 
 <!-- the below i use for jquery -->
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>
<body>
<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="#">Navbar</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">
        <ul class="navbar-nav mr-auto">
            <li class="nav-item active">
                <a class="nav-link" href="{{'addcategory'}}">Add Catgory <span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="{{'showcategory'}}">show Category</a>
            </li>
            <li class="nav-item dropdown">
                <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                    Manage Products
                </a>
                <div class="dropdown-menu" aria-labelledby="navbarDropdown">
                    <a class="dropdown-item" href="{{'
                    addproducts'}}">Add Products</a>
                    <a class="dropdown-item" href="#">Another action</a>
                    <div class="dropdown-divider"></div>
                    <a class="dropdown-item" href="#">Something else here</a>
                </div>
            </li>
            <li class="nav-item">
                <a class="nav-link disabled" href="#">Disabled</a>
            </li>
        </ul>
        <form class="form-inline my-2 my-lg-0">
            <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
            <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
        </form>
    </div>
</nav>
@yield('content')

</body>
@yield('scripts')
</html>

您的nav.blade.php可能如下所示。

@extends('layouts.main')
@section('content')
    <table class="table">
        <thead>
        <tr>

            <th scope="col">id</th>
            <th scope="col">name</th>
            <th scope="col">Delete</th>
            <th scope="col">Update</th>
            <th scope="col">Get Products</th>
        </tr>
        </thead>
        <tbody>
        @foreach($categories as $cat)
        <tr>

            <td>{{$cat->id}}</td>
            <td>{{$cat->name}}</td>
            <td><a class="btn btn-danger" href="{{url('delete',$cat->id)}}">Delete</a> </td>
            <td><a class="btn btn-danger" href="{{url('update',$cat->id)}}">update</a> </td>
            <td><a class="btn btn-danger" href="{{url('getproductjoin',$cat->id)}}">getproducts</a> </td>

        </tr>

        @endforeach
        </tbody>
    </table>
    <button id="hello" class="btn btn-danger">hello</button>

    @endsection
@section('scripts')
<script >
    $(document).ready(function() {
        $("#hello").click(function () {
            alert("hello there");
        })
    });
</script>
@endsection

或者您可以遵循组件标准，并且可以为脚本创建一个组件，以将其包含在任何需要的位置。您可以在此处阅读有关Laravel链接的更多信息： https://laravel.com/docs/7.x/blade#components

Answer 2

您只产生内容，也需要产生脚本

</nav>
@yield('content')
</body>
@yield('script')
</html>
