Retrieve button value

You can use jQuery val() function to retrieve buttons' value as shown below.

HTML

<button class="btn1"  name="btn1" value="button1">
    Label</button>

JavaScript

<script type="text/javascript">
    $(function() {
        $('.btn1').click(function() {
            alert($(this).val());
        });
    });
</script>

 This will display the value button1.
