我知道如何在我的应用程序使用活动打开时检查互联网连接.但是,当我的应用程序未运行时,如何检查服务中的连接？

有没有办法证明联系人是否在Viber应用程序上？

换句话说,是否有可能获得Connection电话号码的列表？

我在用着jquery-ui。两周后我无法解决这个问题。

我不知道为什么点击滑块后出现此错误：

火狐控制台：

TypeError: o.element is undefined[Learn More]  jquery-ui.min.js:6:6058\n

控制台镀铬：

我想在cookie中设置并获取值,但它不起作用:

    Cookie::queue('online_payment_id', "1", 15);

    $value = Cookie::get('online_payment_id');
    dd($value);

dd()回报null;

我用下面的方式,但我收到了这条消息:

Method cookie does not exist.

    request()->cookie('online_payment_id');

    $value = response()->cookie('online_payment_id', "1", 15);
    dd($value);

我正在关注这个教程：

但是当我在浏览器中输入此网址时，我的应用程序没有启动：

我有一个阿拉伯语单词列表。

我该如何排序（按字母排序）？

更新 ：

如何将 arrabicCollat​​or 设置为 Collections ？

    Locale arrabic= new Locale("ar");\n    Collator arrabicCollator = Collator.getInstance(arrabic);\n\n    Collections.sort(arr_items, new Comparator<Helper>() {\n\n\n        @Override\n        public int compare(Helper one, Helper two) {\n            // TODO Auto-generated method stub\n            return one.getTitle().compareTo(two.getTitle());\n        }\n\n    });\n

解决了 ：

    Locale arabic = new Locale("ar");\n    final Collator arabicCollator = Collator.getInstance(arabic);\n\n\n    Collections.sort(arr_items, new Comparator<Helper>() {\n\n\n        @Override\n        public int compare(Helper one, Helper two) {\n            // TODO Auto-generated …

我想创建一个目录,但是我收到了这个错误:

ErrorException in Filesystem.php line 390: mkdir(): No such file or directoryErrorException in Filesystem.php line 390: mkdir(): No such file or directory


 in Filesystem.php line 390
at HandleExceptions->handleError('2', 'mkdir(): No such file or directory', 'C:\xampp\htdocs\yatan\yatan\vendor\laravel\framework\src\Illuminate\Filesystem\Filesystem.php', '390', array('path' => 'C:\xampp\htdocs\yatan\yatan\public/assets/images/projects/1/1476592434/', 'mode' => '511', 'recursive' => false, 'force' => false))

我的代码:

    $to_main_image = time();
    $path = 'assets/images/projects/'.$user_id.'/'.$to_main_image.'/';
    File::makeDirectory(public_path().'/'.$path,0777);

我想将一个视图的顶部设置到另一个视图的底部。像这样：

A是B一个符号，显示我想对视图执行什么操作。

我希望A（图像视图）符号始终位于B（图像视图）符号下方。

B视图固定在父视图的水平中心和顶部。

我正在使用laravel-excel库来读取 Excel 文件。

http://www.maatwebsite.nl/laravel-excel/docs/import

   //http://localhost:8000/assets/panel/excel/test123.xls
    $address = URL::to('/assets/panel/excel/').'/test123.xls';
   // dd($address);
    Excel::load($address, function($reader) {

        $results = $reader->get();
        dd($results);

    });

该文件http://localhost:8000/assets/panel/excel/test123.xls存在，但我收到此错误：

Could not open C:\xampp\htdocs\tahrircenter\http://localhost:8000/assets/panel/excel/test123.xls for reading! File does not exist.

我知道错误的含义，但是如何使用我的地址而不是该库中的目录地址？

我想使用history库，但收到以下消息：

TypeError: (0 , _history.createBrowserHistory) is not a function

我的助手：

import { createBrowserHistory } from 'history';

export const historyHelper = createBrowserHistory();

package.json：
