问题
I'm in frame 1 of a movie, and I want to use getChildByName("mc_movieclip"); to get a reference to mc_movieclip. The problem is that mc_movieclip does not exist in frame 1 but only in frame 5. How can I get a reference to this MovieClip, even though it's in another frame?
回答1:
The easiest way to fix this is that you put a copy of mc_movieclip on frame 1 and make it hidden. mc_movieclip.visible=false will do the trick.
Note: if your mc has animation (in its timeline) then you have to restart that animation on frame 5 to get the same effect as before.
