Laravel中通过按钮删除数据行无响应问题求助

Hey there! Let's get that delete button working properly. The main reason it's not doing anything right now is that your submit button isn't wrapped in a <form> element, and Laravel requires a specific HTTP method to handle delete operations correctly.

Here's what you need to adjust in your view code: #

Wrap your delete button and CSRF token inside a form that points to your destroy route, and add the DELETE method spoofing directive:

@foreach ($scores as $score)
<tr>
    <td>{{ $score->id }}</td>
    <td>{{ $score->serialnumber }}</td>
    <td>{{ $score->name }}</td>
    <td>{{ $score->created_at }}</td>
    <td></td>
    <td>
        <!-- Add the form wrapper here -->
        <form action="{{ route('cd.destroy', $score) }}" method="POST">
            @csrf <!-- This replaces your csrf_field() -->
            @method('DELETE') <!-- Required for Laravel's resource destroy method -->
            <button class="btn btn-danger" type="submit">Delete this Row</button>
        </form>
    </td>
</tr>
@endforeach

Key explanations: #

• Form wrapper: Without a form, clicking the button has no destination to send the request to—this is why nothing happens right now.
• @method('DELETE'): HTML forms don't natively support DELETE requests, so Laravel uses this directive to generate a hidden input that tells the framework to treat the request as a DELETE operation, which matches your controller's destroy method (assuming you're using resource routes).
• Route targeting: route('cd.destroy', $score) generates the correct URL for deleting the specific $score record—make sure your routes are set up with Route::resource('cd', YourController::class); for this to work.

Your controller code looks good as-is:

public function destroy($delete) { 
    $delete->delete(); 
    return redirect()->route('cd.index')->with('success','deleted successfully!'); 
}

Once you update the view, your delete button should trigger the request properly and redirect you back with the success message.
