I am using the below code to navigate to parent component on click of "Device Hardware Back Button". I am using Capacitor 3.0 and device backbutton works properly. Actual issue is that i am not able to access Class members in the callback function.
Below is the code
export class ConfirmBoxComponent extends DialogContentBase implements OnInit{
constructor(public dialog: DialogRef, public myService : MyService) {
super(dialog);
}
ngOnInit(): void {
this.handleHardwareBackButton();
}
public onCancelAction(): void {
console.log("Cancel confirmed", this.dialog)
myService.closeDialog();// closeDialog not available thru arrow or callback functions
}
handleHardwareBackButton(){
App.addListener('backButton',function(){
this.onCancelAction() //not able to access onCancelMethod within callback
})
}
}
Issue is that i am getting "this.onCancelAction" is not a method. Also i tried below code but no use.
handleHardwareBackButton(){
App.addListener('backButton',function(){
this.dialog.close({ actionConfirmed : false }); //here this line doesn't get executed. Also no errors observed
}.bind(this))
}
Am i going wrong somewhere? Please guide me on how to access class members in a callback function?
Try something like this...
export class ConfirmBoxComponent extends DialogContentBase implements OnInit {
constructor(public dialog: DialogRef) {
super(dialog);
}
ngOnInit(): void {
this.handleHardwareBackButton();
}
public onCancelAction(): void {
console.log("Cancel confirmed", this.dialog)
this.dialog.close({ actionConfirmed: false });
}
handleHardwareBackButton() {
App.addListener('backButton', () => {
this.onCancelAction() //not able to access onCancelMethod within callback
})
}
}
