and merging the data units storing the same document node in the multiple reference data units to obtain multiple target data units.
Optionally, the user may adjust the page configuration information at will to implement initialization of the page, for example, the user changes the page size from the original a4 size to the A3 size, at this time, because the size of the displayed page becomes large, two a4 pages are needed to display the complete document data, after the displayed page is changed into A3 sheets, one displayed page may be sufficient, and at this time, in order to adapt to the page size changed by the user and meet the requirement of page display, in the embodiment of the present application, multiple reference data units obtained by splitting the target data unit are merged into the same target data unit, and the merged target data unit is split according to the page size by using the merged target data unit as the paging standard of the document node.

As an alternative embodiment, splitting the plurality of target data units into the plurality of groups of data units by page size comprises:
and sequentially determining the data unit groups to which the target data units belong according to the sequence of the target data units to obtain a plurality of data unit groups, wherein the size of the data unit contained in each data unit group is smaller than or equal to the page size.
Optionally, in the embodiment of the present application, the data units are sequentially stored in the multiple target data units according to the display order of the document data, and then the data unit groups to which the target data units belong are sequentially determined according to the order of the multiple target data units, because one data unit group corresponds to one page, and one data unit group may contain multiple data units, the size of the data unit contained in each data unit group is smaller than or equal to the page size, if the size of the data unit contained in each data unit group is larger than the page size, a paging situation occurs, and then the current data unit group is split.
As an alternative embodiment, sequentially determining the data unit groups to which the target data units belong according to the sequence of the target data units, and obtaining the data unit groups includes:
selecting a data unit to be grouped from a plurality of target data units according to the sequence of the target data units;
and adding the data unit to be grouped into the current data unit group under the condition that the size of the data unit to be grouped is smaller than or equal to the remaining size of the current data unit group, wherein the remaining size of the current data unit group is the difference between the page size and the total size of the existing data units in the current data unit group.
Optionally, in the embodiment of the present application, multiple target data units may be placed in a queue, where the queue may be understood as a memory for storing the target data units, and then the server sequentially stores the target data units in the queue according to the sequence of the multiple target data units, and then determines whether there are data units that have not been grouped in the queue (i.e., data units to be grouped).
And taking a unit to be grouped as a current data unit, judging whether the display height of the current data unit is smaller than or equal to the residual size of the current data unit group, adding the unit to be grouped into the current data unit group under the condition that the size of the unit to be grouped is smaller than or equal to the residual size of the current data unit group, and modifying the value of the residual size of the current data unit group, wherein the residual size of the current data unit group is the difference value between the page size and the total size of the existing data units in the current data unit group.

As an alternative embodiment, after the data unit to be grouped is selected from the plurality of target data units in the order of the plurality of target data units, the method further comprises:
under the condition that the size of the data unit to be grouped is larger than the residual size of the current data unit group, splitting the data unit to be grouped into a first data unit and a second data unit, wherein the size of the first data unit is smaller than or equal to the residual size;
the first data unit is added to a current group of data units and the second data unit is added to at least one group of data units following the current group of data units.
Optionally, when the size of the data unit to be grouped is larger than the remaining size of the current data unit group, it may be determined first whether the data unit to be grouped can be split, for example, when the document data stored in the data unit to be grouped is a formula or a picture that must be complete, the data unit to be grouped cannot be split, and if the document data stored in the data unit to be grouped is a table or a character, the data unit to be grouped may be split into two data units, and the two data units are sequentially added into the data unit group.
For example, a data unit to be grouped is split into a first data unit and a second data unit, wherein the size of the first data unit is smaller than or equal to the remaining size; and adding the first data unit into the current data unit group, newly building a data unit group when the residual size of the current data unit group is zero, and adding the second data unit into a newly built data unit group behind the current data group. It should be noted that, if the size of the second data unit is larger and one page cannot completely display the document data in the second data unit, the second data unit needs to be added to a plurality of data unit groups, and at this time, the second data unit should be added to at least one new data unit group after the current data group.
According to the embodiment of the application, when the data unit to be grouped is divided into the first data unit and the second data unit, the data unit group is increased in real time according to the sizes of the first data unit and the second data unit so as to achieve the purpose of displaying the complete document data.
As an alternative embodiment, after splitting the plurality of target data units into the plurality of groups of data units by page size, the method further comprises:
rendering each data unit in the data unit group to be displayed as a page view node, wherein the data unit group to be displayed is a data unit group corresponding to a target page to be displayed in the plurality of data unit groups;
and inserting the page view node into the page view of the target paging for displaying.
Optionally, the API rendering tool is used to render each data unit in the data unit group to be displayed into a page view node, where each data unit group corresponds to one paging page, and the data unit included in each data unit group stores document data to be displayed, so that the page view node can be rendered through the data unit, and then the rendered page view node is inserted into the display page.
According to the method and the device, the page view nodes are obtained by rendering the data units in the data unit group, and therefore the target pages to be displayed achieve the online document paging function.
