这应该是一个简单的任务，我还没有完全掌握laravel。 我有我的控制器视图和模型设置。我想使用users.destroy路由删除数据库中的行。但是我想以某种方式做到这一点。我想在页面的警报区域中显示警报，要求确认删除某个用户。我假设我需要将会话中的用户ID传递给警报，以在单击删除按钮时确认我的删除。 如果我单击确认它调用了user.destroy，请单击1按钮在页面顶部打开一个警报。

or
you can use any plugin like
http://myclabs.github.io/jquery.confirm/
http://bootboxjs.com/
In controller
```php
public function deleteposts(Request $request)
{
// your delete code is here
$request->session()->flash('success', 'Post deleted sucessfully');
return redirect()->back();
}
here you setting success message

如果您使用的是Laravel collective HTML，则可以替换该表单标签

这只是一个例子，我正在考虑将您的模型设为User.php
如果要使用图标，只需添加超赞的CSS字体
打开您的User.php模型并粘贴以下代码
/**
* @function tableActionButtons
* @author Manojkiran <manojkiran10031998@gmail.com>
* @param string $fullUrl
* @param integer $id
* @param string $titleValue
* @param array $buttonActions
* @usage Generates the buttons
* @version 1.0
**/
/*
NOTE:
if you want to show tooltip you need the JQUERY JS and tooltip Javascript
if you are not well in JavaScript Just Use My Function toolTipScript()
|--------------------------------------------------------------------------
| Generates the buttons
|--------------------------------------------------------------------------
|Generates the buttons while displaying the table data in laravel
|when the project is bigger and if you are laravel expert you this.
|But if you are the learner just go with basic
|
|Basically It Will generate the buttons for show edit delete record with the default
|Route::resource('foo',FooController);

现在将其添加到User.php
use Illuminate\Support\HtmlString;
现在打开列表index.blade.php，并在for循环迭代中添加以下行
{{ App\User::tableActionButtons(url()->full(),$user->id,$user->name,['delete'],null,false) }}
如果要多个按钮4rt参数接受数组
{{ App\User::tableActionButtons(url()->full(),$user->id,$user->name,['show','edit,'delete],null,false) }}
