The present invention relates to remote control technologies, and provides a method, web server and system for remote control. The method comprises: receiving remote control information sent by a remote-controlling terminal; executing a control instruction on a corresponding webpage in accordance with the remote control information, or sending information on the corresponding webpage back to the remote-controlling terminal and executing a control instruction selected or entered by a user at the remote-controlling terminal based on information on the corresponding webpage; and returning execution result to the remote-controlling terminal in a webpage format so that the remote-controlling terminal can obtain information on current execution result at a remote-controlled terminal based on the returned webpage. The present invention can effectively address the issues of poor usability caused by the need to develop different remote control software for different platforms, and that remote-controlling terminal cannot receive and display execution result of the remote control instruction.
