Flash技巧代码：播放进度控制

onEnterFrame = function () {
      jd_txt.text = "播放进度："+_currentframe+"/"+_totalframes;
      _root.jd_mc.t_mc._x = int(_root._currentframe/_root._totalframes*(300-_root.jd_mc.t_mc._width));
};
_root.jd_mc.k_mc.onPress = function() {
      delete onEnterFrame;
      _root.jd_mc.t_mc._x = _root.jd_mc._xmouse;
};
_root.jd_mc.k_mc.onRelease = function() {
      gotoAndPlay(int(_root.jd_mc.t_mc._x/(300-_root.jd_mc.t_mc._width)*_root._totalframes));
      onEnterFrame = function () {
            jd_txt.text = "播放进度："+_currentframe+"/"+_totalframes;
            _root.jd_mc.t_mc._x = int(_root._currentframe/_root._totalframes*(300-_root.jd_mc.t_mc._width));
      };
};
_root.jd_mc.t_mc.onPress = function() {
      delete onEnterFrame;
      startDrag(this, false, 0, -5, 300-this._width, -5);
      _root.jd_mc.t_mc.onEnterFrame = function() {
            gotoAndPlay(int(_root.jd_mc.t_mc._x/(300-_root.jd_mc.t_mc._width)*_root._totalframes));
            jd_txt.text = "播放进度："+int(_root.jd_mc.t_mc._x/(300-_root.jd_mc.t_mc._width)*_root._totalframes)+"/"+_root._totalframes;
      };
};
_root.jd_mc.t_mc.onRelease = function() {
      stopDrag();
      delete _root.jd_mc.t_mc.onEnterFrame;
      gotoAndPlay(int(_root.jd_mc.t_mc._x/(300-_root.jd_mc.t_mc._width)*_root._totalframes));
      onEnterFrame = function () {
            jd_txt.text = "播放进度："+_currentframe+"/"+_totalframes;
            _root.jd_mc.t_mc._x = int(_root._currentframe/_root._totalframes*(300-_root.jd_mc.t_mc._width));
      };
};
这是我写的播放进度控制。可以拖动进度控制手柄，也可以在进度框中点击。
