Yes, through the ExternalInterface class.
You can make Javascript calls from the Flash movie and get any public page information your heart desires.
Adding
Looking at this after a year and a half, I decided to add a few examples:
Say you have a JS function on your client page, for example:
function foo(bar,type) {
// do something with bar and type
}
You call it from Flash (using AS3) as follows:
ExternalInterface.call(foo, bar, type);
, , .
Flash- Javascript, Flash Flex ( , AS3):
application1_applicationCompleteHandler(event:Event) {
ExternalInterface.addCallback(foo, bar);
}
public function bar(arg1, arg2) : void {
}
Javascript ( myMovie - SWF):
myMovie.foo(anArg, anotherArg);
addCallback , - , .
