In addition, volatile storage media such as random access memory (RAM) or read only memory (ROM) may be configured in the processor 25 .

Fig. 3 is a flow chart of a method for updating a program offline according to an embodiment of the present invention. The following will be described with reference to the embodiments of FIGS. 1 and 2 in conjunction with FIG. 3 . Please refer to FIG. 1 to FIG. 3 , in step S301 , when the network module 24 is connected to the network 101 , the processor 25 obtains the service agent component and the offline execution data from the network server 121 . In step S302, the processor 25 installs and runs the service agent component, and stores offline execution data.

In one embodiment, when the electronic device 111 is in the network connection state, the processor 25 may obtain a service agent component of a specific website from the network server 121 providing network services. The service agent component is a script program that can run behind the stand-alone browser or the embedded browser (independent of the web page). In one embodiment, the service agent component may be a "Service Worker" program. Each website can register with the web browser of the electronic device 111 to install its own "Service Worker", so as to help the user perform some work independently when the user browses to his own website. In particular, the installed "Service Worker" can be run offline. In other words, the processor 25 obtains the service proxy component from the network server 121 via the network 101 and installs the service proxy component in the storage circuit 23 in advance.

In one embodiment, after the service proxy component is installed, the service proxy component will be activated (activated) to control the web pages within the jurisdiction, and at the same time, the service proxy component can cache offline execution data and web page related data , so as to store the offline execution data in the browse memory in the storage circuit 23 . The above-mentioned browsing memory generally refers to the storage elements used by web browsers to store data in the form of text, files, program codes, etc., such as Application Cache, Local Storage, Session Storage, Indicator Database (IndexDB) and more.

Afterwards, in step S303 , when the network module 24 is not connected to the network 101 , the processor 25 triggers the service agent component to access the offline execution data through the embedded browser of the application program to obtain the offline execution result. In step S304, the processor 25 executes an operation according to the offline execution result through the application program.

In one embodiment, when the electronic device 111 is offline from the network, the processor 25 can run the embedded browser by running the application program. Based on this, even in the offline state, since the embedded browser of the application program is required to call the corresponding service agent element, the service agent element will also run or read the offline execution data acquired in the connection state. In one embodiment, the webpage related data and offline execution data obtained in the connection state may include pictures, videos, animations, JavaScript codes, FLASH animation data, Cascading Style Sheets (CSS) and so on. In particular, the offline execution data may include the offline program code of the application program, for example, the program code conforming to the html5 specification.

Therefore, the service proxy component can run and read and write 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 program, the offline program code itself or the content of the offline webpage, etc. . Finally, the processor 25 can perform an operation according to the offline execution result through the application program, such as presenting offline webpage content through the application program, changing the parameter setting of the application program, changing the offline service setting of the application program, and updating the offline program of the application program Code and so on.

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

Please refer to FIG. 4 first, the electronic device 111 can be loaded with an independent browser 233 and an application program 231 . The application program 231 is embedded with an embedded browser 232 , so that the application program 231 can present webpage content through the embedded browser 232 . Here, the stand-alone browser 233 and the embedded browser 232 can use the common browser core component 234 to acquire data related to the webpage conforming to the HTML specification. The browser core component 234 includes a service proxy component 235 and a browsing memory 236 .

In one embodiment, both the stand-alone browser 233 and the embedded browser 232 can be coupled to the web server 121 through the network 101 in a connected state, so that the web server 121 can obtain content related to web pages. When the user uses a web browser (stand-alone browser 233 or embedded browser 232) to link to the specific website established by the web server 121, the web server 121 can transfer the program of the service agent component 235 about this specific website Data B1 is provided to the web browser. The processor 25 completes the installation or update of the service agent component 235 according to the program data B1.

In addition, when the user uses a web browser (standalone browser 233 or embedded browser 232) to connect to the web server 121, the browsing memory 236 can store the latest offline execution data A1 provided by the web server 121 and some The data related to the webpage is cached in the browsing memory 236 in the storage circuit 23 . In one embodiment, the service proxy element 235 can assist the web browser to cache the related data of the web pages browsed, so even in the connection state, the service proxy element 235 can also assist the web browser to extract some previously browsed data from the browsing memory 234. The related data of the web page has been saved, so as to avoid downloading the related data of the repeated web page and save network traffic. It is worth mentioning that once the developer of the application program 231 releases the latest version of the offline execution data A1 , the connected electronic device 111 can immediately obtain the offline execution data A1 of the application program 231 via the network 101 .

Next, please refer to FIG. 5 , when the electronic device 111 is offline (the network module 24 is not connected to the network 101 ), the application program 231 may request the embedded browser 232 to call the service proxy component 235 . Therefore, the called service agent component 235 will access the offline execution data A1 related to the application program 231 from the browse memory 236 . The service agent component 235 runs the offline program code in the offline execution data A1 and reads and writes the offline service related data in the offline execution data A1, and generates an offline execution result C1 accordingly. Based on this, the application program 231 can obtain the offline execution result C1 generated by the service agent component 235 through the software communication interface 237 bridging 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 program 231 can be updated in the offline state according to the offline execution result C1. In addition, the software communication interface 237 is a component interface enabling 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 program codes.

In an application example, assuming that the application program 231 is a Taiwan Railway ticketing application, a user can purchase or inquire about a Taiwan Railway ticket through the Taiwan Railway ticketing application. The service agent component 235 of the Taiwan Railway website has been downloaded and installed when the electronic device 111 is in the connection state. And, the latest Taiwan Railway timetable and the offline program code (that is, the offline execution data A1) of the Taiwan Railway ticketing application program can be recorded in the browsing memory 236 through the operation of the service agent component 235 . In this way, when the user opens the Taiwan Railways ticketing application program (that is, the application program 231) in the offline state of the network, the embedded browser 232 in the application program 231 can trigger the service agent component 235 to access the latest The Taiwan Railway timetable and the offline program code of the Taiwan Railway ticketing application to provide users with the latest offline ticketing inquiry service. In this way, through the method of the embodiment of the present invention, the phenomenon that the user obtains the old Taiwan Railway timetable or the offline ticketing query service that has not been updated because the version of the application program 231 is not updated immediately can be avoided.

In addition, in an embodiment, the synchronization component of the stand-alone browser 233 can also synchronize the related settings of the browser component to the embedded browser 232 . More specifically, when the synchronization component starts the synchronization mechanism, the stand-alone browser 233 and the embedded browser 232 can read and write the latest program code B1 of the service agent component 235 and the latest offline execution data A1 in the browser storage 236 synchronously. . Based on this, the embedded browser 232 can subsequently trigger the service agent component 235 to obtain the offline execution data A1. Fig. 6 is a flow chart of a method for updating a program offline according to an embodiment of the present invention. The relevant implementation details and related device features of the method for updating the program offline in this embodiment can be obtained from the descriptions of the above-mentioned embodiments in FIGS. .

Referring to FIG. 6, in step S601, an application program is executed. In step S602, it is determined whether 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 network server obtains the service agent component and the offline execution data. Afterwards, in step S604, install and run the service agent component, and store offline execution data. In addition, the offline execution data in the service agent component and the browsing memory can be updated regularly or irregularly. Therefore, in step S605, when the network module is connected to the network, update the service agent component and browse the offline execution data in the memory. In addition, the application program can normally provide corresponding network services in the connected state.

On the other hand, if the determination in step S602 is negative, in step S606 , the related settings of the browser component of the stand-alone browser are synchronized to the embedded browser, wherein the browser component includes a 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 may be omitted. In step S607, when the network module is not connected to the network, the embedded browser of the application program is used to trigger the service agent component to access the offline execution data. In step S608, the service proxy component runs behind the embedded browser and reads and writes the offline execution data in the browsing memory. In step S609, based on the service request generated by the application program, the application program is used to obtain the offline execution result from the embedded browser through the software communication interface. In step S610, the offline service is provided by the application program according to the offline execution result corresponding to the service request.

To sum up, the method and electronic device for offline program update proposed by the present invention can obtain the service agent components and offline execution data from the network server in the connected state, and use the embedded browser of the application program in the disconnected state The call service agent component accesses offline execution data. Here, the service proxy component can run behind the browser and correspond to a specific website set up by the network service operator, so as to store the offline execution data provided by a network server in the browsing memory. Therefore, when the electronic device is not connected to the network, the application program 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 not connected to the Internet and the application program has not undergone a version update action, the user can obtain the latest offline service information related to the required service. In addition, since program developers only need to maintain offline program codes that can be used across platforms, the burden of maintaining offline programs in multiple programming language versions can be reduced.

Although the present invention has been disclosed above with the embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of protection shall prevail as defined by the claims.
