The embodiment of the application provides a data loading method, as shown in fig. 1, which is applied to a data processing system, wherein the data processing system comprises terminal equipment, such as: computers, notebook computers, tablet computers, mobile phones, portable devices, vehicle-mounted devices, etc., also include network systems such as: an audiovisual service system, a large screen system, a client/server system (C/S), a browser/server system, a cloud computing system, and so forth. The type and architecture of the data processing system is not limited herein. The method comprises the following steps:
s101, monitoring that the display page moves to a preset position, and determining recording point information of a data block to be loaded in the moving direction of the display page. Here, the display page may be, but is not limited to, a web page display page, a form display page, a WeChat display page, or the like; techniques for monitoring the position of movement of a display page are described in detail in the prior art and will not be described in any greater detail herein.
The preset position is generally preset, and may be a preset distance from the current display content to the next data block in the moving direction of the display page, where the moving direction of the display page includes up, down, left, right, and so on, for example, if the current display content in the display page in the mobile terminal is a 100×100 data block (the unit may be a pixel), the moving direction of the display page is down, and the preset position may be a position that is a certain distance from the boundary of the data block in the moving direction, for example, 30 pixels, that is, a position that is a distance from the lower boundary point of the data block is 30 pixels, and the situation that the moving direction is leftward, rightward, and upward is the same as the above example, and will not be described herein too much. The size of the data block can be set according to the need, for example, according to the size of the display screen or the data content and type, and the size of the data block is preferably larger than the size of the display screen.
The recording point information may include coordinate information of at least one boundary point of the data block, the coordinate information may be a number of the boundary point, a two-dimensional coordinate of the boundary point in the data block, and the like, preferably, the coordinate information is a number of the boundary point, and the number of the boundary point may be a number of a minimum data unit data cell in the data block, and may be a row number and/or a column number.
For example, referring to fig. 2, a data block is illustrated, where the size of the data block is 100 rows×100 columns, the data block includes a, b, c, d four boundary points, a point a corresponding to a first column of the first row is an upper left point, or called a start point, a point d corresponding to a 100 th column of the 100 th row is a lower right point, or called an end point, a point b corresponding to a 100 th column of the 1 st row and a point c corresponding to a 1 st column of the 100 th row are an upper right point and a lower left point, respectively, coordinate information of the boundary point a (i.e., a number of data cells, the same applies hereinafter) is (1, 1), coordinate information of the boundary point b is (1, 100), coordinate information of the boundary point c is (100, 1), and coordinate information of the boundary point d is (100 ).
After the computer equipment monitors that the display page reaches the preset position, determining the record point information of the data block to be loaded in the movement direction of the display page according to any one of the following modes:
mode one: acquiring the movement direction of a display page;
determining the recording point information of the next data block in the movement direction of the display page as the recording point information of the data block to be loaded;
in a specific implementation, the moving direction of a scroll bar in a display page is acquired, the recording point information of the next data block adjacent to the current data block is acquired along the moving direction of the scroll bar, and the acquired recording point information is used as the recording point information of the data block to be loaded.
For example, referring to fig. 3, the data blocks are all standard data blocks (data blocks which are not deleted and added are called standard data blocks), the data in the data blocks are 100 rows×100 columns, the recording point information generally includes coordinate information of a start point and coordinate information of an end point, taking 4 data blocks as an example for explanation, the current data block is C1, the data block on the right of the data block C1 is C2, the data block below the data block C1 is C3, the data block on the right of the data block C3 is C4, the recording point information of the C1 includes (1, 1) and (100 ), the recording point information of the data block C2 is (1, 101) and (100, 200), the recording point information of the data block C3 is (101 ) and (200 ), and after determining that the movement direction of the display page is downward, the recording point information of the data block to be loaded is (101, 1) and (200 ), that is the data block to be loaded is C3.
Mode two:
and acquiring the record point information of at least two data blocks adjacent to the data block displayed on the display page, and determining the record point information of the data block to be loaded according to the movement direction of the display page.
In a specific implementation, coordinate information of boundary points of at least two adjacent data blocks in a current data block in a display page is obtained, and the coordinate information of the boundary points in the moving direction is further determined as record point information of the data block to be loaded according to the acquired moving direction of the display page.
In an example of the first continuation, referring to fig. 3, the current data block is C1, the data blocks adjacent to C1 are C2 and C3, the recording point information of C2 and C3 is acquired, after determining that the moving direction of the display page is downward, the recording point information of the data block to be loaded is C3, and the recording point information of C3 is (101, 1) and (200 ).
S102, inquiring the record point information of the data block to be loaded from the cache;
here, the correspondence between the identifier of the loaded data block and the coordinate information of the boundary point is stored in the buffer memory in advance, and each data block may store the coordinate information of at least one boundary point, preferably, the coordinate information of the start point and the coordinate information of the end point corresponding to each data block are stored in the buffer memory. For example, the record point information of the loaded data block is identified as C1 and C2, the record point information of C1 is the start point (1, 1) and the end point (100 ), the record point information of C3 is the start point (101, 1) and the end point (200 ), and the record point information of C1 and the corresponding record point information is the start point (1, 1) and the end point (100 ), and the record point information of C3 and the corresponding record point information is the start point (101, 1) and the end point (200 ) are stored in the cache.
In a specific implementation, after the record point information of the data block to be loaded is obtained, inquiring the boundary point information matched with the record point information of the data block to be loaded from a corresponding relation table between the identification of the cached data block and the coordinate information of the boundary point.
And S103, if the record point information of the data block to be loaded is queried, loading the data block corresponding to the record point information from a cache.
And if the record point information of the data block to be loaded is not queried, acquiring and loading the data block to be loaded from the background based on the record point information of the data block to be loaded.
In the implementation, if the boundary point information matched with the record point information of the data block to be loaded is queried, the fact that the data block corresponding to the record point information is loaded is described, and the corresponding data block can be directly obtained from the cache according to the record point information of the data block to be loaded; if the coordinate information of the boundary point matched with the record point information of the data block to be loaded is not queried, the data block to be loaded is not loaded, the data block to be loaded needs to be acquired from a background (a host or a server) according to the record point information of the data block to be loaded, and after the corresponding data block to be loaded is loaded, the identification of the data block to be loaded and the corresponding record point information are stored in a cache. Therefore, when the user loads the data block stored in the cache again next time, the data can be directly obtained from the cache, the pressure of the front end is reduced, the display speed of the display content is improved, the dependence of the front end on the background is reduced, and meanwhile, the processing pressure of the background is also reduced.
When the corresponding relation table in the cache is queried, the starting point of the data block to be loaded can be used as a query point, the ending point of the data block to be loaded can be used as a query point, and the starting point and the ending point of the data block to be loaded can be used as the query point at the same time.
Taking the starting point of the data block to be loaded as a query point as an example, acquiring the recording point information of the data block to be loaded as (101, 1) and (200 ), acquiring the coordinate information of the starting point of the data block to be loaded as (101, 1), if the recording point information of C1 and C3 is stored in the corresponding relation table of the cache, that is, the recording point information of C1 is the starting point (1, 1) and the recording point information of the ending point (100 ) and C3 is the starting point (101, 1) and the ending point (200 ), querying the corresponding relation table in the cache for the coordinate information of the starting point of C3 when the recording point information matched with the starting point (101, 1) of the data block to be loaded is queried, and acquiring the data block corresponding to the recording point information of C3 from the cache and loading; if only the record point information of C1 is stored in the corresponding relation table of the cache, that is, the record point information of C1 is the start point (1, 1) and the end point (100 ), when the record point information matched with the start point (101, 1) of the data block to be loaded is queried from the corresponding relation table in the cache, the coordinate information matched with the (101, 1) is not queried, at this time, the data block corresponding to the information can be acquired from the background based on the start point (101, 1) of the data block to be loaded and the acquired end point (200 ), and after the data block corresponding to the start point (101, 1) of the data block to be loaded is loaded, the (101, 1) is stored in the cache as the record point information. If the data block to be loaded is a standard data block, the end point of the data block to be loaded can be obtained through calculation.
In the data loading process, the computer equipment detects the change condition of the record point information in the data blocks in the display page, and if the record point information in any data block on the display page is detected to change, the record point information corresponding to the data block in the cache is updated based on the changed record point information; if the fact that the record point information which does not exist on the display page is monitored to change, the stored record point information corresponding to the data block is not updated.
When the change of the record point information in any data block on the display page is monitored, the record point information corresponding to the data block in the cache is updated based on the changed record point information, and the method comprises the following steps:
if the changed data block has more than two boundary points, updating the record point information corresponding to the data block in the cache by utilizing the coordinate information of the more than two boundary points;
if the changed data block only has one boundary point, updating the record point information corresponding to the data block and the record point information corresponding to the next data block along the movement direction of the display page in the cache by utilizing the coordinate information of the boundary point;
and if the changed data block does not have the boundary point, deleting the record point information corresponding to the data block in the cache.
In a specific implementation, a user can add or delete data in a data block through a display page, so the data block is not always a standard data block, when the coordinate information of boundary points in the data block changes, and two or more boundary points are arranged in the changed data block, namely, middle data or boundary points in the data block are deleted or added, but two or more boundary points still exist, at this time, according to the coordinate information of the changed boundary points in the data block, corresponding record point information in a cache is updated, and when the coordinate information of several boundary points in the data block changes, corresponding record point information in the cache is changed; if the coordinate information of the boundary point in the data block changes and only one boundary point exists in the changed data block, if only one row or one column of data is left in the current data block, deleting the record point information corresponding to the data block in the cache by utilizing the coordinate information of the boundary point, and updating the record point information corresponding to the next data block along the movement direction of the display page; if the changed data block does not have a boundary point, that is, the data block is deleted, the record point information corresponding to the data block in the cache is deleted.
Taking 100 rows by 100 columns as examples of data in the loaded data block, the coordinate information of the starting point is (1, 1), the coordinate information of the ending point is (100 ), if a row or a column is deleted in the middle part of the data block, and the deleted row or column does not influence the coordinate information of the boundary point of the current data block, then the coordinate information of the boundary point is unchanged, and the record point information corresponding to the data block in the cache is unchanged.
If the boundary line or column in the data block is deleted, for example, the first line is deleted, but the data block still has two boundary points, the coordinate information of the starting point of the data block will become (2, 1), and the coordinate information of the recording point information of the data block corresponding to the starting point of the data block in the cache will be updated to (2, 1); the 100 th row is deleted, but the data block still has two boundary points, the coordinate information of the end point of the data block will become (99, 100), the coordinate information of the record point information of the data block corresponding to the start point of the data block in the cache will be updated to (99, 100), the situation that the column is deleted is the same as the situation that the row is changed, and the redundant description will not be repeated.
For the case of adding data to the boundary of a data block, in the prior art, when adding row or column data to the data block, the number of the newly added row or column will change according to the last row or column adjacent to the newly added row or column, for example, the number of the current data grid is (2, 1), and when adding one row of data under the current data grid, the number of the data grid under the newly added previous data grid is (3, 1), so long as the data in the data block changes, the number of the boundary point in the data block will change, and the processing pressure of the front end is increased. In this application, when data such as a row or a column is added to a data block, the number of the newly added row or column is sequentially increased over time, and is not dependent on the number of the current row, for example, the data block is a standard data block (100 rows×100 columns), the number of the current data grid is (2, 1), one row of data is added below the current data, the number of the data grid below the newly added previous data grid is (101, 1), after the corresponding data of (101, 1) is added, one row is added after the corresponding data of (10, 1), the number of the newly added data is (102, 1), and as long as the added data is not a boundary point of the data block, no change occurs in coordinate information of the boundary point in the data block.
If a row or column is added to the boundary point in the standard data block, for example, the moving direction is downward, a row is added before the first row of the data block C1, and the row is added for the first time, the coordinate information of the starting point of the data block will become (101, 1), the record point information corresponding to the data block in the cache is updated to (101, 1), and when a row of data is added between the current data block C1 and the next data block C2 in the moving direction, and the row is added for the second time, the coordinate information of the starting point in the record point information of the data block C2 is updated to (102, 1). The case where columns are added is the same as the case where rows are added, and no description will be given.
If a large number of rows and columns are deleted in the data block, and if only one row of data or one column of data remains in the final data block, for example, the current data block is C1 and the coordinate information of the remaining boundary point is (50, 1), the coordinate information of the start point in the record point information of the next data block C3 in the moving direction of the display page is updated to (50, 1).
If the data block is deleted directly, the recording point information of the next data block in the moving direction of the display page is not changed.
