I have to buttons on a page and I want nortification appear on buttons click. But nothing happens. I only added document.getElementByClassName... and buttonController functions. But nortification not working on buttons click.

I know there is way to completely rewrite everything so it would work, but would be nice to know why it's not working that way -it's wierd because I only changed it a slightly.

Here is HTML:

<!DOCTYPE html>

<html>
    <head>
        <meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *; img-src 'self' data: content:;">
        <meta name="format-detection" content="telephone=no">
        <meta name="msapplication-tap-highlight" content="no">
        <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width">
        <link rel="stylesheet" type="text/css" href="css/index.css">
        <title>Button Test</title>
    </head>
    <body>
    <button type="button" class="btn">Click Me!</button>
     <button type="button" class="btn">Click Me too!</button>
    </body>
</html

Here is JavaScript:

var app = {

    initialize: function() {
        document.addEventListener('deviceready', this.onDeviceReady.bind(this), false);
    document.getElementByClassName("btn").addEventListener("click", buttonController());
    },

    onDeviceReady: function() {
        this.receivedEvent('deviceready');
    },

    // Update DOM on a Received Event
    receivedEvent: function(id) {
        var parentElement = document.getElementById(id);
        var listeningElement = parentElement.querySelector('.listening');
        var receivedElement = parentElement.querySelector('.received');

        listeningElement.setAttribute('style', 'display:none;');
        receivedElement.setAttribute('style', 'display:block;');

        console.log('Received Event: ' + id);
    }

    alertDismissed: function () {
    }

    buttonController: function () {
    navigator.notification.alert(
        'Button Pressed!',  // message
        alertDismissed,         // callback
        'Title',            // title
        'Button Name'                  // buttonName
    );
    }
};

app.initialize();

In your html there is no reference to js, also maybe the Dom is not rendered when you call getElementByClassName

I tried to put

<script src="js/index.js"></script>

before <link rel="stylesheet" type="text/css" href="css/index.css">

but nothing changed.

What to do about DOM ?

You have to init your js function in the body onload event of your html

Like that ?

<body onload="buttonController()">

Still not working. Should I remove <script src="js/index.js"></script> ?

app.initzialize(), buttoncontroller is not defined if you don't call app.initialize(). Y

Maybe you have an error in your js, have you installed the dialog plugin?

You have also to include the cordova.js in your html, i suggest you to dive a little more in how to create a cordova/phonegap project and also to study the basic of html5/css3/js and how to debug with chrome.

Thanks a lot, but shouldn't it all be included already (I mean why they did it that way) for basic project ?

Nobody is replying. Does it mean that I'm asking stupid question OR that there really strange stuff happening and nobody knows what problem is and Cordova is tricky and/or not reliable?

whyyyyyyyyyyyyyyyyyyy

You've got a LOT of replies on your post. It's the weekend. Give time for people to come back to work, read your post of ingratitude, and see if they still want to reply.

+1, you got plenty of answers helping you with everything you were doing wrong. If it still doesn't work, you are probably still doing something wrong.
Your question has low quality, instead of adding more answers like "fghfdghdfgh", try providing a sample project with your current code.

Also, there isn't a lot of people on this group nowadays, you should probably go to Adobe forums or Cordova slack

The DOM elements must to be loaded before you can use it

Try this:

<html>

<head>

<title>Button Test</title>

</head>

<button type="button" class="btn">Click Me!</button> 

<button type="button" class="btn">Click Me too!</button>

<script src="cordova.js"></script>

<script src="js/index.js"></script>

</body>

</html>
