Set a timeout for warning in Ionic2
I have created a warning message that I want to close after the set time. Below is my code:
showAlert() {
let alert = this.alertCtrl.create({
subTitle: 'The information you have provided is incomplete or invalid. Please check your entries and check again.'
});
alert.present();
}
showAlert () is the method that will be called after the event. Now I want to set a timeout for it, but I couldn't find any solution for this.

If you want to use a timeout to trigger an alert,
you can use a global function setTimeout()
like this:
showAlert() {
let alert = this.alertCtrl.create({
subTitle: 'The information you have provided is incomplete or invalid. Please check your entries and check again.'
});
setTimeout(()=>alert.present(),3000);
}
If you want to fire after a timeout,
setTimeout(()=>alert.dismiss(),3000);

Instead of using an alert, prefer to use toast for such problems, you can display it for as long as you want.
to use toast, you can proceed as follows:
import {Toast} from 'ionic-native';
Toast.show("The information you have provided is incomplete or invalid. Please check your entries and check again.", '3000', 'center').subscribe(
toast => {
console.log(toast);
}
);
"3000": this is the time you want to display, the time in milliseconds, therefore 3000 = 3 seconds. "center": This is the position of the toast, it can be either top or bottom.
