I suggest using the 'location hack' rather than unsafeWindow.
http://wiki.greasespot.net/Location_hack
Long story short, if you redirect the page location to a javascript:
url (basically the same as typing it into the URL bar), it executes
code in the 'page' context (with access to the wmp plugin etc) as
opposed to in the 'script' context. This stops the script from being
(potentially) 'unsafe'.
Helper functions such as this would help make it a bit easier to do:
function mutePlayer(arg_playerId)
{
location.href = "javascript:(" + function() {
// do something
document.getElementById(arg_playerId).mute = true;
} + ")()";
}
// Similar to above but in fewer lines
function playPlayer(arg_playerId) {
location.href = "javascript:(" + function() {
document.getElementById(arg_playerId).play(); } + ")()";
}
I've not had a proper play with this yet so perhaps this snippet
*might* not work exactly as I've written it, but that's the general
idea.
