Optionally, after the target document rendering module is generated, the target document rendering module may be stored, and the storage location information of the target document rendering module is configured in the page, so that the target document rendering module is loaded and operated according to the configured storage location information when the page needs to call the target document rendering module. For example, after the target document rendering module is generated, the target document rendering module may be stored according to a storage path set by a user, and the storage path set by the user is used as storage location information of the target document rendering module, and the storage location information is configured in a web page.
In this embodiment, the target document rendering module may be loaded when the webpage is opened, or may be loaded when the document rendering request is detected. Preferably, the method further comprises: and responding to the detected document loading request, and loading the target document rendering module according to the pre-configured storage position information. When a document loading request is detected, the target document rendering module is obtained from the pre-configured storage position information and is loaded and operated, so that the influence of loading the target document rendering module on the webpage performance when no document rendering is required can be avoided.

and the document display module is used for receiving the document picture data sent by the document rendering thread and displaying the document picture data through a display device.
Example nine provides, in accordance with one or more embodiments of the present disclosure, a computer device comprising:
one or more processing devices;
storage means for storing one or more programs;
when executed by the one or more processing devices, cause the one or more processing devices to implement the document loading method of any of examples one to seven.
Example ten provides, according to one or more embodiments of the present disclosure, a computer-readable storage medium having stored thereon a computer program that, when executed by a processor, implements a document loading method as recited in any one of examples one to seven.
The foregoing description is only exemplary of the preferred embodiments of the disclosure and is illustrative of the principles of the technology employed. It will be appreciated by those skilled in the art that the scope of the disclosure herein is not limited to the particular combination of features described above, but also encompasses other embodiments in which any combination of the features described above or their equivalents does not depart from the spirit of the disclosure.

5. The method of claim 1, further comprising:
and acquiring the storage position information of the target document rendering module, and configuring the document rendering module based on the storage position information.
6. The method of claim 5, further comprising:
and responding to the detected document loading request, and loading the target document rendering module according to the pre-configured storage position information.
7. The method according to any one of claims 1 to 6, wherein the document to be loaded is a portable document format document.
8. A document loading apparatus, comprising:
the to-be-loaded document position module is used for responding to the detected document loading request and acquiring document position information corresponding to the document loading request;
the document data acquisition module is used for calling a communication interface to send the document position information to a document rendering thread so that the document rendering thread calls a pre-loaded target document rendering module to acquire a document to be loaded according to the document position information and render the document to be loaded to obtain document picture data;
and the document display module is used for receiving the document picture data sent by the document rendering thread and displaying the document picture data through a display device.
9. A computer device, characterized in that the computer device comprises:
one or more processing devices;
storage means for storing one or more programs;
when executed by the one or more processing devices, cause the one or more processing devices to implement the document loading method of any of claims 1-7.
10. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the document loading method according to any one of claims 1 to 7.
