Using droptarget with dot syntax

programming flash

How can I replace this code to use dot syntax instead of slash?


square.origX = _x;
square.origY = _y;

square.onPress = function() {
	this.startDrag();
};
square.onRelease = function() {
	stopDrag();
	if (square._droptarget != "/ball") {
		this._x = this.origX;
		this._y = this.origY;
	}
};

Thanks.
