摘要： The present invention provides a customizing system and a customizing method for converting a desktop application into a web application. A required processing logic may be added by locating an interface element which is needed to be modified, and modifying a callback function of the interface element (interface description data), so as to implement user's operations on local data by a web application. When a user operates on the modified interface element at a browser side, the added processing logic automatically converts the user's operation to a plurality of operations, so that the user may feel that he is operating on a local file at the browser side, rather than a remote file at a server side. The present invention may implement complex webpage function customization, and thus may implement remote operations on local data.
