Answer 1

You can try

import { Component, ViewChild } from '@angular/core';
import { NavController } from 'ionic-angular';
export class MyApp {

    constructor(public navCtrl:NavController){
        var val=this.navCtrl.last();
        console.log("VAL");
        console.log(val);
    }
}

Answer 2

In ionic +2 you can simply use:

this.navCtrl.last().name

Here is a simple example to log the name

constructor(public navCtrl:NavController){
    console.log("Previous Page is called = " + this.navCtrl.last().name);
}

Answer 3

if you want a history/previous page name in ionic you can use this.

this.navCtrl.getPrevious().name;

or

this.nav.getPrevious().name;
