TypeError: Cannot read property 'push' of undefined in Ionic 3

Question

I am trying to redirect to another page after success callback but I am getting this error TypeError: Cannot read property 'push' of undefined

 this.http.post('http://localhost:3030/users', userDetails).subscribe(function 
 successCallback(response) {
  this.navCtrl.push(HomePage);
   }, function errorCallback(response) {
      // response with status 500
  }) ;

you should define ```navCtrl``` , full code please. – Fateme Fazli May 12 '18 at 05:22 — Fateme Fazli, May 12 '18 at 05:22

Use arrow function => like this -

this.http.post('http://localhost:3030/users', userDetails).subscribe(successCallback(response) => {
  this.navCtrl.push(HomePage);
   }, errorCallback(response) => {
      // response with status 500
  }) ;
