how to call action ?

Hi,
I found out how to change lookto from HTML through Javascript.

<script type="text/javascript">
// <![CDATA[


function krpano() 
{
return document.getElementById("krpanoSWFObject");
}


function lookto(toh, tov, fov)
{
krpano().call( "lookto(" + toh +"," + tov + "," + fov + ")" );
}


// ]]>
</script>

but what how to call from HTML action which is in my XML file?

Thank you Michel!
