Triggering javascript with actionscript

I have created a movie clip that, upon completion, I want to shake the browser window using the following javascript that I've embedded in my HTML ...

function shake_xy(n) {
if (self.moveBy) {
for (i = 10; i > 0; i--) {
for (j = n; j > 0; j--) {
self.moveBy(0,i);
self.moveBy(i,0);
self.moveBy(0,-i);
self.moveBy(-i,0);
}
}
}
}
function shake_x(n) {
if (self.moveBy) {
for (i = 10; i > 0; i--) {
for (j = n; j > 0; j--) {
self.moveBy(i,0);
self.moveBy(-i,0);
}
}
}
}
function shake_y(n) {
if (self.moveBy) {
for (i = 10; i > 0; i--) {
for (j = n; j > 0; j--) {
self.moveBy(0,i);
self.moveBy(0,-i);
}
}
}
}
//-->


What would I write in my actionscript to make this happen? I've tried getURL("javascript:shake_x(10)"), but that didn't work.

Thanks in advance -
