权限编辑

路由

Route::middleware('auth')->group(function () {
    .
    .
    .
    // 编辑权限页面
    Route::get('/permissions/{id}/edit', [PermissionController::class, 'edit'])->name('permissions.edit');
    // 执行编辑权限
    Route::post('/permissions/{id}', [PermissionController::class, 'update'])->name('permissions.update');
   // 删除权限
   Route::delete('/permissions', [PermissionController::class, 'destroy'])->name('permissions.destroy');

});

控制器 编辑功能

App/Http/Controllers/PermissionController.php

// 编辑权限
public function edit($id)
{
    $permission = Permission::findOrFail($id);
    return view('permissions.edit', compact('permission'));
}

// 执行编辑权限
public function update($id, Request $request)
{
    $permission = Permission::findOrFail($id);

    $validator = Validator::make($request->all(), [
        'name' => 'required|min:3|unique:permissions,name,' . $id . ',id',
    ]);

    if ($validator->passes()) {
        $permission->name = $request->name;
        $permission->save();
        return redirect()->route('permissions.index')->with('success', '权限编辑成功~~');
    } else {
        return redirect()->route('permissions.edit',$id)->withErrors($validator)->withInput();
    }
}

    if ($permission == null) {
        session()->flash('error', '未找到权限~');
        return response()->json([
            'status' => false
        ]);

    $permission->delete();
    session()->flash('success', '权限删除成功~');
    return response()->json([
        'status' => true

}

前端模版

resources/views/layouts/app.blade.php 添加 jQuery CDN链接

   .
   .
   .
  </body>
  
    <script src="https://code.jquery.com/jquery-3.7.1.js"></script>
    @isset($script)
       {{ $script }}
    @endisset
    
</html>

resources/views/permissions/list.blade.php

<a href="javascript:void(0);" onclick="deletePermission( {{$permission->id}} )"
   class="bg-red-600 text-sm rounded-md text-white px-3 py-2 hover:bg-red-500">删除</a>

以上：onclick="deletePermission( {{$permission->id}} )"，删除按钮绑定。

• 开始书写ajax无刷新删除

</div>

    <x-slot name="script">
        <script type="text/javascript">
            function deletePermission(id) {
