Cordova notification dialogs' wrapper for mixed web app/packaged app

gistfile1.js

/*
Custom wrappers for javascript's alert/confirm/prompt and their respective cordova counterparts:
https://github.com/apache/cordova-plugin-dialogs

Useful if you want to keep the same codebase on a web and a packaged app. Just keep in mind that javascript dialogs are synchronous, while cordova's are not.

Usage (for the prompt):
showPrompt("What's your name?", null, function(value){
	if (value) {
		console.log("Your name: "+ value);
	} else {
		console.log("No name selected");	
	}
});
*/

function showAlert(message){
	if (navigator.notification) {
		navigator.notification.alert(message);
	} else {
		alert(message);
	}
};

function showConfirm(message, callback){
	if (navigator.notification) {
		navigator.notification.confirm(
			message,
			function(buttonIndex){
				callback(buttonIndex == 1);
			}
		);
	} else {
		callback(confirm(message));
	}
};

function showPrompt(message, value, callback){
	if (navigator.notification) {
		navigator.notification.prompt(
			message,
			function(results){
				if (results.buttonIndex == 1) {
					callback(results.input1);
				}
			},
			null,
			null,
			value || null
		);
	} else {
		callback(prompt(message, value));
	}
};
