hi, how can i disable the hardware backbutton in specific view ? i tried to use the cordova event, backbutton - Apache Cordova
document.addEventListener(‘backbutton’, (e) => {
console.info(“Backbutton :)”);
let activeVC = this.navCtrl.getActive();
let page:any = activeVC.instance;
if ((page instanceof ProductPage)) {
let answer = confirm("are u sure?");
if(!answer){
e.preventDefault();
e.stopPropagation();
throw new Error("Action not allowed");
}
}
}, false);
but this isn’t working
