Javascript : Inject inline code to a html tag

I would like to add my Google Analytics tracking event code inline to my input html tag : 

<input class="addtobag">

to have something 

<input class="addtobag" onClick="_gaq.push(['_trackEvent', 'Videos', 'Play', 'Baby\'s First Birthday']);">

I'm asking this as I don't have access to the file that contains the tag so I'm unable to make the change manually so I'm looking for a javascript code that I will put in the head so when that page load, the tracking event code would be injected automatically.

I want the call to be by my input class and not by id.

jQuery is your friend.

How to replace innerHTML of a div using jQuery?

$("#regTitle").html("Hello World");

EDIT

Guess I didn't read this one, but still same principle.

$(".addtobag").click(_gaq.push(['_trackEvent', 'Videos', 'Play', 'Baby\'s First Birthday']));

Why do you want to do it inline?

document.getElementById('ctl00_mainContentPlaceHolder_lvLookProducts_ctrl0_buyArea3493_btnAddToCart').onclick = function () {
    _gaq.push(['_trackEvent', 'Videos', 'Play', 'Baby\'s First Birthday']);
};

To do it by class name, you'll need to do a little more logic:

var inputs = document.getElementsByClassName('AddToBag'),
    i = inputs.length;

while(i--) {
    inputs[i].onclick = function () {
        _gaq.push(['_trackEvent', 'Videos', 'Play', 'Baby\'s First Birthday']);
    }; 
}

Fetching by class name returns a list, so you'll have to loop through to apply the handler.
