How to load javascript on specific page only

Question

Possible duplicate : How to include Javascript in xml-document?

How would I load a javascript file only only checkout pages? We are using onepage checkout. I have tried adding

            <action method="addJs">
                <script>myscript.js</script>
            </action>

To various places on checkout.xml with no success

Answer 1

The page frame for the onepage checkout is loaded in the initial action. Try something like this:

<checkout_onepage_index>
    <reference name="head">  
         <action method="addItem"><type>skin_js</type><name>js/myscript.js</name></action>
    </reference>
</checkout_onepage_index>

Then place your script in your skin directory under /js.

Hope that helps!

Thanks, Joe
