如何在 laravel 子刀片文件中使用 jquery

[英]how to use jquery in a laravel child blade file

您好,我是 laravel 的新用戶 7. 我想在刀片文件中使用 jquery。 如果我創建一個刀片文件並在其頂部提到所有頭部和身體,然后在其中提供 jquery 的鏈接,那么它就可以正常工作。 但在我的例子中,我創建了一個 nav.blade.php 文件,我在其中放置了所有導航頭和主體代碼。 然后我創建另一個文件並在該文件的頂部擴展導航文件,但在這種情況下 jquery 不起作用

nav.blade.php代碼

<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 文件這是我要使用 jquery 的文件,上面的文件在這個文件里面擴展

@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 不起作用。 請幫我

您需要遵循 Laravel 語法和標准來執行此操作。 您可以為應用程序創建標准布局文件。 main.blade.php ,在該文件中,您可以根據需要設置@yield所需的內容。 例如你的 main.blade.php 可以是這樣的:

<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>

你的 nav.blade.php 看起來像這樣。

@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

或者您可以遵循組件標准,並可以為您的腳本創建一個組件,以將其包含在您喜歡的任何地方。 您可以在此處閱讀有關 Laravel 鏈接的更多信息: https://laravel.com/docs/7.x/blade#components

你只需要 yield 內容,你還需要 yield 腳本

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

將其添加到代碼的底部
