Finally, the processor 25 can perform an operation according to the offline execution result through the application, such as presenting offline web content through the application, changing the parameter settings of the application, changing the offline service setting of the application, updating the offline code of the application, etc. And so on.

In order to clearly illustrate the present invention, FIG. 4 is a schematic diagram of an electronic device in a connection situation according to an embodiment of the present invention. FIG. 5 is a schematic diagram illustrating an electronic device in an offline situation 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 231. The application program 231 has an embedded browser 232 embedded therein, so that the application program 231 can present webpage content through the embedded browser 232. Here, the independent browser 233 and the embedded browser 232 can use a common browser core component 234 to obtain data related to a webpage that complies with the HTML specification. The browser core element 234 includes a service proxy element 235 and a browsing storage 234.

In an embodiment, both the independent browser 233 and the embedded browser 232 can be coupled to the web server 121 via the network 101 in a connection state, so that the web server 121 can obtain the webpage-related information. Content. When a user uses a web browser (a standalone browser 233 or an embedded browser 232) to connect to a specific website created by the web server 121, the web server 121 may use a service proxy component 235 for this particular website. The program data B1 is provided to the web browser. The processor 25 completes the installation or update of the service agent element 235 according to the program data B1.

In addition, when a user uses a web browser (standalone browser 233 or embedded browser 232) to connect to the web server 121, the browsing storage 236 can upload the latest offline execution data provided by the web server 121 A1 and some webpage-related data are 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 data related to the webpage that has been viewed. Therefore, the service proxy element 235 can also assist the web browser to retrieve some of the past data from the browsing storage 234 even when it is connected Information about webpages you have visited to avoid downloading duplicate webpage-related data and save network traffic. It is worth mentioning that once the developer of the application 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 231 from 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 program 231 may request the embedded browser 232 to call the service agent element 235. Therefore, the called service agent component 235 will access the offline execution data A1 related to the application 231 from the browsing storage 236. The service agent component 235 runs the offline code in the offline execution data A1 and reads and writes the offline service related data in the offline execution data A1, and generates the 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 of the embedded browser 232, and perform an offline operation in an offline state according to the offline execution result C1. For example, the existing offline program of the application program 231 may 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 enables the embedded browser 232 and the application 231 to communicate with each other. The software communication interface 237 allows the embedded browser 232 and the application 231 to call each other's code.

In an application example, it is assumed that the application program 231 is a ticket purchase application of the Taiwan Railway, and a user can purchase or query the ticket of the Taiwan Railway through the ticket purchase application of the Taiwan Railway. The service agent component 235 of the Taiwan Railways website has been downloaded and installed when the electronic device 111 is online. In addition, the latest Taiwan Railway timetable and offline code of the Taiwan Railway ticket purchase application (that is, the offline execution data A1) can be recorded in the browsing memory 236 through the operation of the service agent element 235. In this way, when the user opens the Taiwan Railways ticketing application (ie, application 231) when the network is offline, the embedded browser 232 in the application 231 can trigger the service agent component 235 to save the data from the browsing storage 236. Obtain the latest Taiwan Railway timetable and offline code of the Taiwan Railway Ticketing Application to provide the latest offline ticket inquiry service to users. 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 ticket inquiry service that has not been updated because the version of the application 231 is not immediately updated can be avoided.

In addition, in an embodiment, the synchronization component of the independent browser 233 can further synchronize the related settings of the browser component to the embedded browser 232. More specifically, when the synchronization mechanism is enabled, the independent browser 233 and the embedded browser 232 can read and write the code B1 of the latest service agent element 235 and the latest offline execution data A1 in the browser storage 236 in synchronization with each other. . 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 flowchart of a method for updating a program offline according to an embodiment of the present invention. The relevant implementation details and related device characteristics of the method for offline updating the program in this embodiment can be obtained from the above description of the embodiments of FIGS. 1 to 5, and sufficient teachings, suggestions and implementation methods can be obtained, which will not be repeated here. .

Referring to FIG. 6, in step S601, an application program is executed. In step S602, it is determined whether it is connected to the network. If it is determined as YES in step S602, 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. After that, in step S604, the service agent component is installed and run, and the offline execution data is stored. In addition, the offline execution data in the service agent component and the browsing storage can be updated periodically or irregularly. Therefore, in step S605, when the network module is connected to the network, the service agent component is updated and the offline execution data in the storage is browsed. In addition, the application can provide corresponding network services normally when connected.

On the other hand, if the determination in step S602 is no, in step S606, the relevant settings of the browser components of the independent browser are synchronized to the embedded browser, where the browser components include 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 proxy of the application program is used to trigger the service proxy component to access the offline execution data. In step S608, the service agent component runs behind the embedded browser and reads and writes offline execution data in the browsing storage. 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 application program is used to provide the offline service according to the offline execution result corresponding to the service request.

To sum up, the method and electronic device for updating the program offline according to the present invention can obtain service agent components and perform data offline by the network server in the connected state, and use the embedded application program in the unconnected state. The browser calls the service agent component to access offline execution data. Here, the service agent component can be run behind the browser and corresponds 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 storage. 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 not connected to the network and the application has not yet undergone the update of the version, the user can obtain the latest offline service information related to the requested service. In addition, because the program developer only needs to maintain offline code 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 as above with the examples, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some modifications and retouching without departing from the spirit and scope of the present invention. The protection scope of the present invention shall be determined by the scope of the attached patent application.
