Javascript, get the name of a clicked button

Trying to get the id or name of the button that has been clicked. But I only get an undefined message in the popup when I try to access the id or name of the button. Could someone point me in the right direction to get this working?

<!DOCTYPE html PUBLIC "-//W2C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Testing : Buttons</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
</head>

<div id="buttons" style="width:100%;height:100%">
    <p id="custom_buttons" >
    </p>
</div>

<div id="footer">
</div>

<script type="text/javascript">
$(function() {
    var datasetPresets = ["Python", "Java", "C++"];
    var datasetPresetsContainer = $("#custom_buttons");
    $.each(datasetPresets, function(index, value) {
        datasetPresetsContainer.append("<button class=std_buttons value=" + value + ">" + value + "</button>");
    });

    $("button.std_buttons").click(function () {
        var button = $(this);
        alert(button.id);
    });

});

</script>
</body>
</html>
</html

In pure javascript, you would do something like this

$("button.std_buttons").click(function (event) {
    var button = event.target;
    alert(button.id);
});

read more about event object here https://developer.mozilla.org/en/docs/Web/API/Event

Basically, try

alert(this.id);

instead of

alert(button.id);

But this question shows a minimum research effort, because it has been answered multiple times here, and a simple search would suffice:

you just use attr(), the properties are accessed using the attr("property name") in jquery

button.attr('id');

or just

 $(this).id

You need to use attr() to get the id of your button because button is a jQuery object:

alert(button.attr('id');

or you can keep your selector but do not convert it to jQuery object:

var button = this;
alert(button.id);
