Cordova - window.alert → Native Notifications

cordova-native-notifications.js

document.addEventListener('deviceready', function () {
  if (navigator.notification) { // Override default HTML alert with native dialog
    window.alert = function (message) {
      navigator.notification.alert(
        message,    // message
        null,       // callback
        "Notification Title", // title
        'OK'        // buttonName
      );
    };
  }
}, false);

This snippet requires adding the native dialogs plugin to your project:

cordova plugin add org.apache.cordova.dialogs
