Interaction between web pages and local applications

摘要

There is disclosed a local application for a client machine such as a wireless device, and a method of operating the client machine. In an embodiment, the local application is responsive to an external trigger instruction via a web page in a web browser of the client machine, authenticating data access or functions of the local application. The local application may provide data maintained by the local application (e.g. in accordance with a form specified by the external trigger instruction invoking the local application). The external trigger instruction may be an invocation instruction embedded therein such as an extension embedded into the header or content type of the web page. The web page may further include field ID tags mapping specific data fields in the local application's data store to form input fields provided in the web page.
