[Greasemonkey] Calling a function in GM from injected HTML

[Arvid Jakobsson]

function RemoveGroup(event)
{
alert(event.target.id) //event.target is the clicked element, this
will alert 'foo'
}

var anchor=document.getElementById('foo'); // get a refernence to the a
anchor.addEventListener('click', RemoveGroup, true);

In conclusion: the object passed to the handler (RemoveGroup) is an
event object. Most intresting property of the event object is target,
which is the node that fired the event.
