The invention discloses systems and methods for developing, publishing, installing and operating application programs based on a Web
operating system (WebOS). The development
system comprises a development toolkit, a norm setting module and a shared
library writing module, wherein the development toolkit is used for compiling a shared
library; the norm setting module is used for providing a set of norms which access an
extended object in the shared
library from a
JavaScript; and the shared library writing module writes the shared library according to the norms. A set of publishing and operating norms based on the WebOS is set by the application program development
system; the application programs of the shared library, which comprise a hyper text mark-up language (
HTML) page, the
JavaScript and a self-defined binary primary object library, are allowed to be packaged and published according to the norms of an interface; when an application program
package is published to a target platform for installation, the binary primary object library is allowed to be dynamically registered into an engine which is used by the application programs, so the aim that the application programs can finish calling bottom-layer functions of the
system by a
JavaScript engine according to the certain norms is fulfilled.
