Therefore, the service proxy component can run and read and write the offline execution data to obtain the corresponding offline execution result, and the offline execution result obtained by the service proxy component is, for example, the offline parameter setting of the application, the offline code itself or the offline webpage content, and the like. Finally, the processor 25 can perform an operation according to the offline execution result through the application, such as displaying the offline webpage content through the application, changing the parameter setting of the application, changing the offline service setting of the application, updating the offline code of the application, and the like. Wait for the operation.

In order to clearly illustrate the present invention, FIG. 4 is a schematic diagram of an electronic device in a connected scenario according to an embodiment of the invention. FIG. 5 is a schematic diagram of an electronic device in an offline situation according to an embodiment of the invention.

Referring first to FIG. 4, the electronic device 111 can be loaded with a separate browser 233 and an application 231. The application 231 has an embedded browser 232 embedded therein, so that the application 231 can render the webpage content through the embedded browser 232. Here, the standalone browser 233 and the embedded browser 232 can use the common browser core component 234 to obtain web page related material conforming to the HTML specification. Browser core component 234 includes service proxy component 235 and browsing storage 234.

In an embodiment, the independent browser 233 and the embedded browser 232 can be coupled to the network server 121 via the network 101 in a connected state, so as to be related to the webpage by the network server 121. Content. When the user connects to a particular website established by the web server 121 using a web browser (independent browser 233 or embedded browser 232), the web server 121 can service the proxy element 235 for the particular website. The program data B1 is provided to the web browser. The processor 25 completes the installation or update of the service proxy component 235 in accordance with the program data B1.

In addition, when the user connects to the web server 121 using a web browser (independent browser 233 or embedded browser 232), the browsing storage 236 can provide the latest offline execution data provided by the web server 121. A1 and some web page related data are cached in the browsing storage 236 in the storage circuit 23. In an embodiment, the service proxy component 235 can assist the web browser to cache the webpage related data that has been browsed, so that even if it is in the connected state, the service proxy component 235 can assist the web browser to extract some of the information from the browsing storage 234. Webpage related information that has been viewed to avoid downloading duplicate webpage related data and save network traffic. It is worth mentioning that once the developer of the application 231 publishes the latest version of the offline execution material A1, the electronic device 111 in the connected state can immediately acquire the offline execution material A1 of the application 231 via the network 101.

Next, referring to FIG. 5, when the electronic device 111 is offline (the network module 24 is not connected to the network 101), the application 231 may request the embedded browser 232 to call the service proxy component 235. Accordingly, the called service agent component 235 will access the offline execution material A1 associated with the application 231 from the browsing storage 236. The service proxy component 235 runs the offline executable code in the offline execution data A1 and reads and writes the offline service related data in the offline execution data A1, and accordingly generates the offline execution result C1. Based on this, the application 231 can obtain the offline execution result C1 generated by the service proxy component 235 by bridging the software communication interface 237 of the embedded browser 232, and perform an offline operation in the offline state according to the offline execution result C1. For example, the existing offline program of the application 231 can be updated in an offline state according to the offline execution result C1. In addition, the software communication interface 237 is a component interface that allows the embedded browser 232 and the application program 231 to communicate with each other. The software communication interface 237 allows the embedded browser 232 and the application program 231 to call each other's code.

In an application example, it is assumed that the application 231 is a platform purchase ticket application, and the user can purchase or inquire about the railway ticket through the platform purchase application. The service agent component 235 of the Taiwan Railway website has been downloaded and installed when the electronic device 111 is in the connected state. Moreover, the latest Taiwan Railway Timetable and the offline code of the Taiwan Railway Ticketing Application (ie, offline execution data A1) can be recorded in the browsing storage 236 through the operation of the service agent component 235. In this way, when the user opens the platform purchase application (ie, the application 231) in the offline state, the embedded browser 232 in the application 231 can trigger the service proxy component 235 to save from the browsing storage 236. Take the latest Taiwan Railway Timetable and the offline code of the Taiwan Rail Ticketing application to provide the latest offline ticketing inquiry service to users. As a result, the method of the embodiment of the present invention can avoid the phenomenon that the user obtains the old railway schedule or the offline ticket purchase service that has not been updated because the version of the application 231 is not updated immediately.

Moreover, in an embodiment, the synchronization component of the standalone browser 233 can synchronize the relevant settings of the browser component to the embedded browser 232. More specifically, when the synchronization component turns on the synchronization mechanism, the standalone browser 233 and the embedded browser 232 can simultaneously read and write the latest code A1 of the service proxy component 235 and the latest offline execution profile A1 of the browser store 236. . Based on this, the embedded browser 232 can trigger the service proxy component 235 to obtain the offline execution profile A1. FIG. 6 is a flowchart of a method for offline updating a program according to an embodiment of the invention. Related implementation details of the method for offline update program of this embodiment and related device features may be obtained from the above descriptions of the embodiments of FIG. 1 to FIG. 5, and sufficient teachings, suggestions, and implementation manners are obtained, and details are not repeated herein. .

Referring to FIG. 6, in step S601, an application is executed. In step S602, it is determined whether or not to connect to the network. If the determination in step S602 is YES, in step S603, when the network module is connected to the network, the service proxy component and the offline execution data are obtained by the network server. Thereafter, in step S604, the service agent component is installed and run, and the offline execution material is stored. In addition, the service agent component and offline execution data in the browsing storage can be updated periodically or irregularly. Therefore, in step S605, when the network module is connected to the network, the service proxy component is updated and the offline execution data in the storage is browsed. In addition, the application can provide the corresponding network service normally in the connected state.

On the other hand, if the determination in step S602 is no, in step S606, the relevant settings of the browser component of the independent browser are synchronized to the embedded browser, wherein the browser component includes the service proxy component. However, it should be noted that although step S606 is performed in the embodiment shown in FIG. 6, the execution of step S606 is optional. In other embodiments, the execution of step S606 can be omitted. In step S607, when the network module is not connected to the network, the service proxy component is triggered to access the offline execution data through the embedded browser of the application. In step S608, the service agent component runs behind the embedded browser and reads and writes the offline execution data in the storage. In step S609, based on the service request generated by the application, the offline execution result is obtained from the embedded browser via the software communication interface by the application. In step S610, the offline service is provided by the application according to the offline execution result corresponding to the service request.

In summary, the method and the electronic device of the offline update program proposed by the present invention can obtain service proxy components and offline execution data from a network server in a networked state, and are embedded in an unconnected state by an application. The browser calls the service proxy component to access the offline execution data. Here, the service proxy component can be stored in the browsing storage by running the offline execution data provided by a network server in a specific website that can be run behind the browser and corresponding to the network service provider. Therefore, when the electronic device is not connected to the network, the application can update the offline program or provide the latest offline service based on the offline execution result generated by the service agent component. In this way, even if the electronic device is currently in an unconnected state and the application has not undergone the update action of the version, the user can obtain the latest offline service information related to the requested service. In addition, because programmers only need to maintain offline code that can be used across platforms, the burden of maintaining offline programs in multiple programming languages can be reduced.
