anyone know how we used ionic modal object in static methods

[Bhumin Bhandari]

@Injectable()

export class commonLib {

loading: Loading;

constructor(

private loadingCtrl: LoadingController,

private alertCtrl: AlertController,

public modalCtrl: ModalController,

) { } 

static commonAlertPopup(response_message, flag) {

let commonAlert = this.modalCtrl.create(

"CommonAlertPage",

{ alertMsg: response_message, successflag: flag },

{

showBackdrop: false,

enableBackdropDismiss: false,

leaveAnimation: "forward"

}

);

commonAlert.present();

}

}

while I define commonAlertPopup as static type then this.modalCtrl cause error : [ts] Property 'modalCtrl' does not exist on type 'typeof commonLib

Expected :

how we access this.modalCtrl.create in static method?

You can not access 'this' inside static methods.

As this commonLib is already Injectable, You can use its instance with Angular's dependency injection and remove static from method signature and make it simple class method.

Example, inside a component, you can inject this commonLib class, like 

import {CommonLib} from 'path to this file'

...

constructor(private commonLib: CommonLib){

}

and use it like 

this.commonLib.commonAlertPopup(....)

Also please change the class name to start with a Capital letter, which is a better convention.
