The target selector is used for determining a storage path of the local file in the current mobile terminal device, and for example, the target selector may be a filePicker selector. The target buffer is used for downloading the online file to the storage unit of the current mobile terminal device, and for example, the target buffer may be a FileDownloader buffer.
In this embodiment, the target selector and the target buffer may be preconfigured into the file preview component, and the target selector or the target buffer is directly invoked when determining the target preview file. For example, if the target preview document is a local document, a filePicker selector may be invoked, and the local document management page is jumped to by the filePicker selector to select the target preview document, thereby determining a storage path of the target preview document. If the target preview file is an online file, a FileDownloader buffer may be invoked, through which the storage path of the target preview file is determined.

In this embodiment, if the target preview file is determined to be an online file, the target buffer is invoked, and the target buffer may download the target preview file to the storage unit of the current mobile terminal device according to the cloud address corresponding to the target preview file, so that the target buffer may jump to the local file management page to select the target preview file, thereby determining the storage path of the target preview file.
S260, loading the target preview file based on the to-be-used loading tool kit and the storage path.
In this embodiment, after determining the loading tool and the storage path to be used, the loading tool to be used may find the target preview file according to the storage path, and then load the target preview file into the file preview program embedded in the target application program.
S270, displaying the target preview file based on the file preview component.
According to the technical scheme provided by the embodiment of the invention, firstly, when the file preview program embedded in the trigger target application program is detected, a file preview component is configured in a current page, wherein the file preview component is used for loading and displaying a target preview file, the file preview component comprises at least one file loading tool package, and then the loading tool package to be used corresponding to the system platform type is determined from the file preview component according to the system platform type to which the file preview program belongs. And then determining a target preview file from the files to be previewed based on triggering operation of a target user, judging the file type corresponding to the target preview file, determining a storage path of the target preview file based on the file type corresponding to the target preview file, loading the target preview file based on a loading tool kit to be used and the storage path, and finally displaying the target preview file based on a file preview component, thereby solving the technical problems of low efficiency of file preview and limited application scene in the process of previewing the file, realizing convenient preview of local files and online files based on the file preview component, realizing cross-platform file preview, improving convenience of previewing the file, and further enhancing the efficiency of loading the target preview file.
As an alternative to the above embodiment, the implementation steps of the above method are shown in fig. 5. Can be summarized as: when the user triggers the file preview program, the file preview component is added to the currently displayed page. The file preview component can judge the type of the operating system of the current mobile terminal device, if the operating system is an Android operating system, the type of the system platform can be determined to be a first system platform, a first loading tool package is determined to be a loading tool package to be used, and further TBSReaderView can be returned and a TBS kernel is initialized; if the mobile terminal device currently used by the user is an iOS operating system, the system platform type can be determined to be a second system platform, the second loading tool package is determined to be the loading tool package to be used, and further the WKWebView can be returned and initialized. Then, the user can determine the target preview file by triggering a control corresponding to each file to be previewed, the file preview component further judges the file type of the target preview file, if the target preview file is a local file, a FilePicker selector can be called, and the target preview file is selected by jumping to a local file management page through the FilePicker selector, so that the storage path of the target preview file is determined; if the target preview file is an online file, a FileDownloader buffer may be invoked, through which the storage path of the target preview file is determined. And finally, the loading tool to be used can find the target preview file according to the storage path, and further load the target preview file into the file preview program embedded in the target application program and display the target preview file.
