Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the embodiments of the present application.

[0018] Referring to Figure 1A , a flowchart of the steps of the document display method of the online education platform according to the first embodiment of the present application is shown.

[0019] Specifically, the document display method of the online education platform provided in this embodiment includes the following steps:

[0020] In step S101, the software development kit of the online education client sends an instruction for indicating the business scenario of the online education client to the document engine of the online education client.

[0021] In this embodiment, the software development kit generally refers to a collection of development tools used by software engineers when building application software for specific software packages, software frameworks, hardware platforms, operating systems, etc. Broadly speaking, the software development tool refers to a collection of relevant documents, examples, and tools for assisting in the development of a certain type of software. The document engine refers to a network system that, according to certain strategies, uses computer programs to search for document resources existing on the network, organizes and processes the document information, and displays the processed information to users, and is a network system dedicated to providing document retrieval services for users. The business scenarios include at least one of the following: document business, flow business, interruption business, and user business. It can be understood that the above description is only exemplary, and this embodiment does not make any limitations in this regard.

[0022] In step S102, the document engine configures the document display function corresponding to the business scenario of the online education client indicated by the instruction according to a preset function configuration rule, so as to obtain the document display function corresponding to the business scenario of the online education client.

[0023] In this embodiment, the function configuration rule can be understood as a configuration rule generated according to the correspondence between the business scenario and the document display function. The document display function includes at least one of the following: pen, animation demonstration, annotation, page turning, and laser pointer. It can be understood that the above description is only exemplary, and this embodiment does not make any limitations in this regard.

[0024] In some alternative embodiments, before the document engine configures the document display function corresponding to the business scenario of the online education client indicated by the instruction according to a preset function configuration rule, the method further includes: the software development kit configures the document display function corresponding to the business scenario, establishes the correspondence between the business scenario and the document display function, and then sends the correspondence to the document engine; the document engine pre-sets the function configuration rule according to the correspondence. Thus, the document engine can pre-set the function configuration rule according to the correspondence between the business scenario and the document display function sent by the software development kit, and thus can accurately obtain the document display function corresponding to the business scenario of the online education client. It can be understood that the above description is only exemplary, and this embodiment does not make any limitations in this regard.

[0025] In a specific example, the software development kit does not need to care about any document drawing operations, which are uniformly managed by the document engine and can be protocolized and customized according to the needs of different business logics. Specifically, according to the different requirements of business scenarios, the multi-scenario of the document engine can be realized by customizing the function protocol. It can be understood that the above description is only exemplary, and this embodiment does not make any limitations in this regard.

[0026] In some alternative embodiments, the method further includes: the software development kit sending an instruction to the document engine for indicating to erase a partial document display function corresponding to the business scenario of the online education client; the document engine erasing the partial document display function corresponding to the business scenario of the online education client according to the instruction for indicating to erase the partial document display function corresponding to the business scenario of the online education client. Thereby, through the instruction for indicating to erase the partial document display function corresponding to the business scenario of the online education client, the document engine can effectively erase the partial document display function corresponding to the business scenario of the online education client. It can be understood that the above description is only exemplary, and this embodiment does not make any limitation thereto.

[0027] In a specific example, the document engine can be responsible for the erasure operations of all the related functions such as the paintbrush, animation, annotation, etc. of the software development kit. It can be understood that the above description is only exemplary, and this embodiment does not make any limitation thereto.

[0028] In step S103, the document engine selects an application programming interface and a callback method that match the document display function, and assembles the application programming interface and the callback method to obtain a function module corresponding to the document display function.

[0029] In this embodiment, the document engine calls the corresponding application programming interface and callback method according to the application scenario of the online education platform, and can flexibly implement document display functions such as page turning, animation, paintbrush, laser pointer, etc. through the integrated unified external interface. In addition, through the preset function configuration rules, the application programming interface and the callback method can be flexibly assembled to meet the customization requirements in different scenarios. It can be understood that the above description is only exemplary, and this embodiment does not make any limitation thereto.

[0030] In step S104, the document engine calls the function module corresponding to the document display function, and sends the operation result of the function module to the script manager of the online education client.

[0031] In this embodiment, the document engine calls the function module corresponding to the document display function through the application programming interface, and sends the operation result of the function module to the script manager of the online education client. It can be understood that the above description is only exemplary, and this embodiment does not make any limitation thereto.

[0032] In step S105, the script manager generates a rendering instruction for document display based on the running result of the functional module, and sends the rendering instruction for document display to the document rendering core of the online education client.

[0033] In step S106, the document rendering core renders the document display interface of the online education client according to the rendering instruction for document display, so as to obtain the display result of the document display function corresponding to the business scenario.

[0034] In some optional embodiments, the method further includes: the script manager registers to listen for a web view control associated with the document display interface and a JS callback method, processes the listened events, and then sends the processed events to the software development kit in a protocol proxy manner. Thus, by specifically registering the script manager to listen for the web view control associated with the document display interface and the JS callback method, it is not necessary for the software development kit to directly listen for the web view control associated with the document display interface and the JS callback method, thereby achieving decoupling from the software development kit and avoiding the risk of resource unrelease and memory leakage caused by strong references. It can be understood that the above description is only exemplary, and this embodiment makes no limitation thereto.

[0035] In some optional embodiments, the method further includes: the script manager coordinates the interaction between the web view control associated with the document display interface and the JS callback method associated with the document display interface. Thus, by coordinating the interaction between the web view control associated with the document display interface and the JS callback method associated with the document display interface by the script manager, it is not necessary for the software development kit to coordinate the interaction between the web view control associated with the document display interface and the JS callback method associated with the document display interface, thereby achieving decoupling from the software development kit and avoiding the risk of resource unrelease and memory leakage caused by strong references. It can be understood that the above description is only exemplary, and this embodiment makes no limitation thereto.

[0036] In some optional embodiments, the method further includes: the document engine configures the mask of the document display interface according to the document display mode, so that different document display modes correspond to different masks. Thus, the display function of the dynamic mask can be realized. It can be understood that the above description is only exemplary, and this embodiment makes no limitation thereto.

[0037] In a specific example, the document display mode includes at least one of the following: scaling proportionally, stretching to fill, filling proportionally, centering proportionally. The document engine can configure the mask correspondingly according to different display modes such as scaling proportionally and stretching to fill of the current document, so as to complete the display function. It can be understood that the above description is only exemplary, and this embodiment does not make any limitation thereto.

[0038] In some alternative embodiments, the method further includes: the document engine determines, according to the relative relationship algorithm, the relative parameters of the document display position and size of the script manager and the document display position and size of the document display interface in the same display mode, and adjusts the mask corresponding to the same display mode according to the relative parameters, so as to perform corresponding document display on the document display interface. Thereby, display effects such as document scaling, deformation, and stretching that cannot be satisfied by the existing JS drawing engine are achieved. It can be understood that the above description is only exemplary, and this embodiment does not make any limitation thereto.

[0039] In some alternative embodiments, the method further includes: the document engine expands the document display function corresponding to the business scenario of the online education client according to the requirements of the business scenario of the online education client. Thereby, the document display function corresponding to the business scenario of the online education client can be expanded. It can be understood that the above description is only exemplary, and this embodiment does not make any limitation thereto.

[0040] In a specific example, according to the business scenario, corresponding configuration rules and custom protocols are added to the document engine for modular assembly. It can be understood that the above description is only exemplary, and this embodiment does not make any limitation thereto.
