Displaying notification in Ionic 2

Displaying notification in Ionic 2

Whenever I click on the register button, if I fill out all the fields I am taken to the regsuccess page. Otherwise, I receive a message saying to fill in all required fields.

However, I want to display an alert message using Ionic2 and TypeScript.

HTML:

<button primary full (click)="register()" >Register</button>
     <p>{{regMsg}}</p>

.ts file:

 
register(){
    var _this= this;

    // this.submitAttempt = true;

    if(!this.registrationForm.valid){
       _this.regMsg = "Please enter all required fields";
    }
    else {
        console.log("success!")
        console.log(this.registrationForm.value);
        _this.navCtrl.setRoot(RegThankyouPage);

    }
