I have implemented toast
using ToastController
in my ionic2
project . Currently i am facing an issue with the duplicate toast
messages . Is there any way to prevent the duplication / overlapping of toast message in ionic2 / angular2
(NB : Duplication means when I click on a button I am displaying a toast , if I click on the same button multiple times the toast messages overlaps ) ?
export class <className>{
constructor(private toast:ToastController){
}
showToast(message) {
let toast = this.toastCtrl.create({
message: message,
duration: 2000,
position: 'bottom'
})
toast.present();
}
}
I am calling this method on an button click .
with duplicates toast (taken example using toastr , same sitaution is for me)
when i enable "prevent notification" , the duplicate toast are not there within the timeout duration .
Any help is much appreciated.
You can use a property on that page to know if a toast is being shown or not before showing a new one.
import { ToastController, Toast } from 'ionic-angular';
// ...
private isToastVisible: boolean;
constructor(private toastCtrl: ToastController) { }
presentToast() {
if(this.isToastVisible) {
return;
}
this.isToastVisible = true;
const toast: Toast = this.toastCtrl.create({
message: 'User was added successfully',
duration: 3000,
position: 'top'
});
toast.onDidDismiss(() => {
this.isToastVisible = false;
});
toast.present();
}
import { ToastController } from '@ionic/angular';
// ...
private isToastVisible: boolean;
constructor(private toastCtrl: ToastController) { }
presentToast() {
if(this.isToastVisible) {
return;
}
this.isToastVisible = true;
this.toastCtrl.create({
message: 'User was added successfully',
duration: 3000,
position: 'top'
}).then((toast: HTMLIonToastElement) => {
toast.onDidDismiss().then(() => {
this.isToastVisible = false;
});
toast.present();
})
}
