标签: zone

I would like to use zone.js in my Angular project ( not just the runOutsideAngularZone function ).

I tried to include it like this:

import { zone } from 'zone.js';

Unfortunately I get this error:

error TS2306: File 'C:/projects/MyApp/node_modules/zone.js/dist/zone.js.d.ts' is not a module.

Then I removed the { zone } part:

import 'zone.js';

But now I get this error:

error TS2552: Cannot find name 'zone'. Did you mean 'Zone'?

My code is this:

    let myZoneSpec = {
        beforeTask: function () …

我正在使用datetimepicker，需要将从params获得的字符串datetime保存到特定于用户的特定时区中的datetime。这将使我可以将适当的UTC日期时间保存到数据库中。

params[:notify_at] #=> "2014-07-05 14:30:00"

user.time_zone #=> #<ActiveSupport::TimeZone:0x00000007535ac8 @name="Warsaw", @utc_offset=nil, @tzinfo=#<TZInfo::TimezoneProxy: Europe/Warsaw>, @current_period=nil>

我想做些类似的事情：

date = params[:notify_at].to_datetime(user.time_zone) #=> Sat, 05 Jul 2014 12:30:00 +0000
(its 14:30 in user's localtime but 12:30 in UTC)

我有一个充满用户的数据库,每个用户都有一个timezone存储为字符串的列(例如America/New_York).(而且我知道将它们作为偏移存储在数据库中会更有意义,但不能为此项目完成)我有一个表单,用户可以更改其时区.这是我的第一个方法:

我有这个填充下拉(value=> display):

protected $timezones = [
    '+00:00' => '(UTC +00:00) Western European Time',
    '+01:00' => '(UTC +01:00) Central European Time',
    '+02:00' => '(UTC +02:00) Eastern European Time',
    '+03:00' => '(UTC +03:00) Further-Eastern European Time',
    '+04:00' => '(UTC +04:00) Gulf Standard Time',
    '+05:00' => '(UTC +05:00) Pakistan Standard Time',
    '+05:30' => '(UTC +05:30) Indian Standard Time',
    '+05:45' => '(UTC +05:45) Nepal Time',
    '+06:00' => '(UTC +06:00) British Indian Ocean Time',
    '+07:00' => '(UTC …

我有一个本地脚本角度应用程序，它运行蓝牙服务来连接到外围设备（设备）。该应用程序会显示一个标签，其中包含一条消息，指示尚未将蓝牙设备连接到运行该应用程序的移动设备。我想做的是更新 UI，以便标签在发生连接时消失（并在发生断开连接时重新出现）。

应用程序组件.tns.html

<StackLayout orientation="vertical" marginBottom="50">
  <Label text="No bluetooth device detected." id="noBluetoothWarning" horizontalAlignment="center" color="#B11" *ngIf="bluetoothDisconnected" marginTop="30" visibility="{{ isBluetoothConnected ? 'collapsed' : 'visible' }}"></Label>
</StackLayout>

export class NSAppComponent extends AppComponent implements OnInit {


  pageData: Observable;

  ngOnInit() {
    this.bluetoothDisconnected = true;

    let _page = <Page>topmost().currentPage;
    _page.actionBarHidden = true;
    _page.frame.bindingContext = this.pageData;

    let that = this;

    this.bluetoothScanner.connectionStateChangeEvent.subscribe((connectionState) => {
      that.log.debug(`Am I in an angular zone? ${NgZone.isInAngularZone()}`);
      this.ngZone.run(() => {

        that.log.debug(`connectionStateEvent triggered! state is: ${connectionState}`);

        that.bluetoothDisconnected = !connectionState;

        that.pageData.set("isBluetoothConnected", connectionState);
