A flash content navigation method, a mobile electronic device, and a computer-readable medium are provided, wherein the flash content is embedded in a web page, and a visible area within the web page is predetermined for displaying at least a portion of the flash content. In the method, when receiving a flash navigating signal, a full screen interface is popped up. If a size of the visible area is greater than that of the touch screen, the flash content is scaled down to make the flash content displayed in the visible area fit the size of the touch screen, and the flash content displayed in the visible area is played back by a scaled size. When receiving a flash interacting signal from the touch screen, the flash interacting signal is transmitted to a flash engine to perform an action on the flash content according to the flash interacting signal.
