高手来来来，flash代码含义
俺是新手
请教一下这段代码的含义
sub.gotoAndStop(this._name);
myURL = [ "category1.htm", "category1.htm", "category1.htm","category1.htm"]
for (i=1; i<=myURL[this._name-1].length; i++) {
sub[i].onRollOver = function() {
_global.over = this._parent._parent._name;
};
sub[i].onRollOut = sub[i].onDragOut=function () {
_global.over = active;
};
sub[i].onRelease = function() {
getURL(myURL[this._parent._parent._name-1][this._name-1], "_self");
};
}
