flash as3，代码，鼠标点击跳转帧

你这样，下一贞的按钮不会响应的，用addFrameScript试试

package {

import flash.display.MovieClip;
import flash.events.MouseEvent;
public class 前后连接 extends MovieClip {

public function 前后连接() {
// constructor code
last1.addEventListener(MouseEvent.CLICK,clicking1);
next1.addEventListener(MouseEvent.CLICK,clicking2);
quit1.addEventListener(MouseEvent.CLICK,clicking3);
}//你的少了这个
public function clicking1(event:MouseEvent) {
gotoAndPlay(prevFrame);
}

private function clicking2(event:MouseEvent) {
gotoAndPlay(nextFrame);
}

protected function clicking3(event:MouseEvent) {
gotoAndPlay(2);
}

}
}
//最后多了个{，已经去掉本回答被提问者采纳
