Hi,
I have one firebase database, name branch, one of the key(phone) has value(607123456),
Inside html page, I can use {{ (branch | async)?.phone }} to get the value.
But now I have a function “callUs(stringNumber)”, how do I use {{ (branch | async)?.phone }} as the argument of this callUs function? So that I can pass different phone number to this function.

“callUs({{ (branch | async)?.phone }})” gets a template syntax error.

Somebody help. Thank you

My method
close(){

this.file.writeFile(this.file.externalRootDirectory, ‘mydir.txt’, ‘Test’ ,{ replace: false, append: true });

}

Thank you for your support :wink:

This message is directed to the creators of Ionic.

There seems to be a lot of answers but no real solutions to a problem I am trying to solve. So the problem is:
Please indicate by way of example (ionic 2+) with Typescript how to construct a complex object before sending this object to this.http.post method.
Also please indicate MIME-TYPE /CONTENT TYPE as well.
If you have the example of the receiving method ASP.NET WepAPI that would be surely welcome.

Thank you.

Some code first, this is from a small provider I created for data synchronization process,

import { ApiServicesProvider } from "../../providers/api-services/api-services";

import * as moment from "moment";

@Injectable()
export class DataSyncProvider {

  connected: Subscription;
  disconnected: Subscription;

  constructor(
    public plfm: Platform, public net: Network,
    private undev: UnderDevelopment,
    private storage: Storage,
    private alertCtrl: AlertController,

    });

    this.connected = this.net.onConnect()
      .subscribe(result => {
        console.log(JSON.stringify(result));
        this.alertCtrl.create({
          title: 'Available network',
          message: 'Synchronize offline data before continuing using.',
          buttons: [{
            text: 'Sync',
            handler: () => this.loadSchedules()
          }]
        });
      });

    this.disconnected = this.net.onDisconnect()
      .subscribe(result => {
        console.log(JSON.stringify(result));
        this.alertCtrl.create({
          title: 'Offine network',
          message: 'Consecutive data changes will be saved offline.',
          buttons: [{
            text: 'Acknowledge',
            handler: () => this.undev.addLater('Now storing data offline!')
          }]
        })
      });
  }

  loadSchedules() {

    var today = moment().format("YYYY-MM-DD");

    this.undev.addLater(`Loading schedules today: ${today}`);

    // TODO: real request here
    // this.storage.set('db.synced', true);

  }

}

As you can see, those two onConnect() and onDisconnect() work badly!
I can see lots of people struggle on this issue lately
(well, I didn’t add setTimeout(...) like the API document suggests, just because it’s makes me wait like forever)

But unexpectedly, that onchange() works great! It just gives right values at right time,
of course when network connection is truly available

so what you guys think?

I got few pages work perfectly, but the problem is when building into apk (I’m working only on Android for now), those images defined in .scss files are not loaded.
I see that only those embedded in img or ion-img elements are working.
