Abstract: A browser based application program extension method and device are provided. In response to a request to activate an application program, a page file and a browser core may be loaded. A script object may be embedded into the browser core to interact with other serving assemblies in an operation environment of the application program. The browser core may parse the page file and generate and display a corresponding application interface. The script object may receive a request from the application interface and invoke a serving assembly according to the request. The script object may return an invoked result to the application interface. Thus, the application program may be developed by combining web technology with the browser core. This may shorten application program development period and reduce development difficulty. Further, the application program may be used in any operating system without extra development effort.

Abstract: A remote operation method includes the following steps: receiving a remote operation request; returning a webpage interface for remote operation according to the remote operation request; receiving an operation instruction sent via the webpage interface; responding to the operation instruction and returning information corresponding to the operation instruction. A remote operation system is also disclosed. The above-mentioned method and system transmit the operation instruction through the webpage interface without need of real-time transmission of the computer operation screen, which can save the amount of the data to be transferred, so the demand for network bandwidth and the data processing amount by the control terminal and controlled terminal are both reduced.
