timeline.clearFrames([startFrameIndex [, endFrameIndex]])
startFrameIndex A zero-based index that defines the beginning of the range of frames to clear. If you omit startFrameIndex, the method uses the current selection. This parameter is optional. endFrameIndex A zero-based index that defines the end of the range of frames to clear. The range goes up to, but does not include, endFrameIndex. If you specify only startFrameIndex, endFrameIndex defaults to the value of startFrameIndex. This parameter is optional.
Nothing.
Method; deletes all the contents from a frame or range of frames on the current layer.
The following example clears the frames from Frame 6 up to, but not including, Frame 11 (remember that index values are different from frame number values):
fl.getDocumentDOM().getTimeline().clearFrames(5, 10);The following example clears Frame 15:
fl.getDocumentDOM().getTimeline().clearFrames(14);
