Yes, you can use jQuery/javascript to do this.

Generally, you should assign either an ID or a class to your input element to easily identify exactly which control fired the event.

Suppose you have this input button:

<input type="button" id="mybutt" value="Click Me">

To alert when button is clicked:

$(document).ready(function() {
    $('#mybutt').click(function() {
        alert('it was pressed');
    });
});

The $(document).ready(function() { bit makes sure that the page (DOM) has loaded all elements first, before it allows the code to bind events to them, etc. This is important.

NOTE THAT before you use jQuery commands, you must first ensure the jQuery library has been referenced/loaded on your page. Most times we do this in the <head> tags, like so:

<head>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>

but it can be loaded any time before the jQuery code.
