Method, device and terminal units for transmitting data

The invention discloses a method, a device and terminal units for transmitting data, and belongs to the field of terminal units. The method includes starting an interactive interface of a first client side; detecting operation implemented by a user and acquiring a data type of data corresponding to specified operation when the specified operation is detected; transmitting the data and the data type of the data to a second client side via communication connection between the first client side and the second client side, and enabling the second client side to process the data according to the data type of the data. The first client side and the second client side can be interacted with each other via interactive interface. The specified operation includes data dragging operation and data pasting operation on the interactive interface. The method, the device and the terminal units have the advantages that a visual, simple and convenient mode for transmitting the data among the terminal units is provided, manual operation is simple, excessive manual intervention in a transmission procedure is prevented, and the error rate is reduced.
