Detailed Description
The core of the invention is to provide a data rolling loading method. In the prior art, data is deleted midway during browsing, which may cause changes in the data of the database, and certainly, the real-time paging of the database may be inconsistent, and the final result may cause data displayed on the interface to be missing. Referring to fig. 1, fig. 1 is a schematic diagram illustrating a page display after deleting previous data in a scroll loading process in the prior art. Referring to fig. 1, before data is added and deleted, the database has 6 pieces of data in total, 3 pieces of data per page, and there are two pages of data, and the current user acquires the first page of data, and displays data 1, 2, and 3; even after deletion, the rolling load gets more data, which is to be taken to data 4, 5, 6. However, after the deletion operation occurs, the database becomes the right diagram in fig. 1, and at this time, the pages are changed into data 4, 5, which is divided into the first page, and the second page has only data 6, so that the second page data taken by the user has only data 6, and obviously, the missing of data 4, 5 shows.
The data rolling loading method provided by the invention comprises the steps of acquiring data deletion information; the data deleting information comprises a deleting time identifier when the data is deleted and deleting position information of the deleted data; determining the number of deleted loaded data in the browsing process according to the deletion time identifier and the deletion position information, and recording the number as the number to be supplemented; acquiring a page turning-down instruction; the data required to be displayed on the current page are obtained again according to the page turning-down instruction, and the data with the quantity equal to the quantity to be supplemented are selected from back to front to serve as the data to be supplemented; and filling the data to be supplemented to the front end of the page to be queried, and continuously loading the data on the page to be queried according to the page-down instruction.
The number of the deleted loaded data in the rolling loading process can be determined according to the deletion time identification and the deletion position information in the data deletion information, then the data of the current page is pre-loaded during loading, the same number of data are taken out from the end of the data of the current page, and the taken out data are data which cannot be displayed when the next page is loaded. At the moment, when the next page is loaded again, the data which is taken out is loaded preferentially according to the quantity when the next page is loaded, and the accuracy of data display can be ensured.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2, fig. 2 is a flowchart of a data rolling loading method according to an embodiment of the present invention.
Referring to fig. 2, in the embodiment of the present invention, a data scrolling loading method includes:
s101: and acquiring data deletion information.
In the embodiment of the present invention, the data deletion information includes a deletion time identifier when deleting data and deletion position information of deleted data. That is, in the embodiment of the present invention, when a certain data in the database is deleted, data deletion information is issued at the same time. The data deleting information specifically includes the time for deleting the data, namely, a deleting time identifier; and the position of the deleted data, for example, the number of pieces of deleted data, i.e., deletion position information. The data deletion information is information describing deleted data from a space dimension and a time dimension, and specific content of the data deletion information may be set according to an actual situation, which is not specifically limited herein. In general, the deletion time is identified as a time stamp of the deletion data.
S102: and determining the deleted quantity of the loaded data in the browsing process according to the deletion time identifier and the deletion position information, and recording the deleted quantity as the quantity to be supplemented.
In the browsing process, that is, the browsing of the user, all processes from the first page loading to the present, specifically browsing in the browsing process, that is, loading a plurality of pages, or only loading the current page, may be performed, and is not specifically limited herein according to the specific situation. It should be noted that the loaded data does not only include data whose value is already loaded, but includes all data whose number of pages is less than the current number of pages. That is, if the browsing process is started from the third page, the data corresponding to the first page and the second page are also regarded as the loaded data in the embodiment of the present invention.
Because the unloaded data with the page number larger than the current page number does not influence the page display when some data in the unloaded data is deleted. Therefore, in this step, the number of deleted loaded data in the browsing process is specifically determined according to the deletion time identifier and the deletion position information. Specifically, this number is recorded as the number to be replenished in this step.
It should be noted that this step may also be executed after S103, that is, after the page down instruction is acquired, the amount to be replenished is calculated. In this case, the step may specifically be: and determining the quantity of the deleted loaded data in the browsing process based on the deletion time identifier and the deletion position information according to the downward page turning instruction, and recording the quantity as the quantity to be supplemented.
It should be further noted that, the present step is generally embodied as: and comparing the deletion time identifier with the first loading time identifier in the browsing process, determining the deleted quantity of the loaded data in the browsing process by combining the deletion position information, and recording the deleted quantity as the quantity to be supplemented. That is, in the embodiment of the present invention, when a certain page is loaded for the first time in the browsing process, a corresponding first loading time identifier, which is usually a first loading time stamp, is generated. In this step, the deletion time identifier in the data deletion information is compared with the first loading time identifier, and the deleted position information is combined to specifically determine the deleted number of the loaded data in the browsing process, and the deleted number is recorded as the number to be supplemented.
S103: and acquiring a page-down instruction.
In this step, the page down command is usually a user dragging a scroll bar to the bottom, or a command input through a preset button in the page, which is not specifically limited herein as the case may be. The page turning-down instruction represents that the user needs to load the data of the next page, and correspondingly, in the subsequent step, the data of the next page needs to be loaded according to the specific page number of the next page and the specific number of data pieces needing to be displayed on the page.
S104: and re-acquiring the data required to be displayed on the current page according to the page-down instruction, and selecting the data with the quantity equal to the quantity to be supplemented from back to front as the data to be supplemented.
In this step, after the page down instruction is obtained, the data loaded on the current page is reloaded, that is, the data required to be displayed on the current page is obtained again. Then, the last n pieces of data are selected from the reloaded current page, where n is equal to the number to be supplemented determined in S102. That is, in this step, the data whose amount is equal to the amount to be supplemented is selected from back to front as the data to be supplemented. It should be noted that the data to be supplemented is data that may be erased in the prior art and cannot be normally displayed on the next page.
It should be noted that this step generally needs to be executed when the amount to be supplemented is not zero, that is, this step generally includes: and when the quantity to be supplemented is not zero, re-acquiring the data required to be displayed on the current page according to the downward page turning instruction, and selecting the data with the quantity equal to the quantity to be supplemented from back to front as the data to be supplemented. When the number to be supplemented is zero, the corresponding data can be directly loaded according to the number of pages of the next page and the specific displayed data number of the next page by referring to the prior art. Thereby avoiding redundant steps to be performed when no loaded data is deleted.
It should be emphasized that, when the current page is reloaded, the data in the current page is only loaded according to the number of pages corresponding to the current page and the number of data pieces that can be actually loaded by the current page, without referring to the number to be supplemented. Correspondingly, in the browsing process, the number to be supplemented can be continuously accumulated.
S105: and filling the data to be supplemented to the front end of the page to be queried, and continuously loading the data on the page to be queried according to the page-down instruction.
And the page to be inquired is the next page to be displayed according to the page down turning instruction. In this step, the obtained data to be supplemented is filled to the front end of the page to be queried, and data continues to be loaded in the remaining space of the page to be queried in sequence, so as to fill the whole page to be queried. In general, when a page to be queried is loaded, data to be supplemented is filled to the front end of the page to be queried first, and then the number of pages corresponding to the page to be queried and the number of remaining loaded data of the page to be queried are sent to a database, so that loading of all data of the page to be queried is completed.
The data rolling loading method provided by the embodiment of the invention comprises the steps of acquiring data deletion information; the data deleting information comprises a deleting time identifier when the data is deleted and deleting position information of the deleted data; determining the number of deleted loaded data in the browsing process according to the deletion time identifier and the deletion position information, and recording the number as the number to be supplemented; acquiring a page turning-down instruction; the data required to be displayed on the current page are obtained again according to the page turning-down instruction, and the data with the quantity equal to the quantity to be supplemented are selected from back to front to serve as the data to be supplemented; and filling the data to be supplemented to the front end of the page to be queried, and continuously loading the data on the page to be queried according to the page-down instruction.
The number of the deleted loaded data in the rolling loading process can be determined according to the deletion time identification and the deletion position information in the data deletion information, then the data of the current page is pre-loaded during loading, the same number of data are taken out from the end of the data of the current page, and the taken out data are data which cannot be displayed when the next page is loaded. At the moment, when the next page is loaded again, the data which is taken out is loaded preferentially according to the quantity when the next page is loaded, and the accuracy of data display can be ensured.
The following embodiments of the present invention will be described in detail with reference to a specific example of a data scrolling loading method provided by the present invention.
In the prior art, since the data returned to the interface each time the page is paged is not invariable, the data source grouped based on the page is constantly changed and may be increased. That is, even if the database is informed of the same page number and how much data is contained in each page, the results returned twice may not be the same because the number of data sources to be grouped increases, resulting in the different data contained in the paging group. Obviously, in such a scenario, the original page containing data is confused, and the data displayed on the interface may be duplicated.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a page display after adding data in a scroll loading process in the prior art. Referring to fig. 3, after data is newly added in the middle, the newly added data is usually at the initial position of the whole database in the actual display process, i.e. the data position corresponding to the first page. As can be seen from fig. 3, the database condition before adding data is shown on the left, which is total 6 pieces of data, and assuming that the user performs paging according to 3 pieces of data per page, the user has already obtained the first page of data, and "data 1, 2, 3" is shown on the interface, and two pieces of data a, B are added to the subsequent database, but the user also performs rolling loading on the original interface to obtain the data of the second page, and at this time, based on paging of the database condition of the right image, the data of the second page is data 2, 3, 4, and obviously, at this time, data 2, 3 appears on the interface repeatedly. In the following embodiments of the invention, the problem of repeated display of data can be solved for the above process.
Referring to fig. 4, fig. 4 is a flowchart illustrating a specific data rolling loading method according to an embodiment of the present invention.
Referring to fig. 4, in the embodiment of the present invention, a data scrolling loading method includes:
s201: and acquiring data adding information.
In the embodiment of the present invention, the data addition information includes an addition time identifier when data is added. Similar to the data deletion information, the data addition information is specifically information generated after the data is newly added to the database, and the information at least needs to include a time identifier when the data is added to the database, that is, an addition time identifier. Typically, the time stamp is a time stamp of the data added to the database. The specific content of the data addition information may be set according to the actual situation, and is not limited specifically herein.
S202: in the browsing process, when data is loaded for the first time, according to the time of loading the data for the first time and the adding time mark, the data with the adding time mark before the time of loading the data for the first time is used as the raw data, and paging loading is carried out on the raw data.
In this step, when a certain browsing starts, that is, when data is first loaded in the browsing, a corresponding time for first loading the data is generated, and the time is usually recorded as a first loading time identifier. In this step, the data in the database is divided into original data according to the time of first loading the data, i.e. the first loading time identifier, the original data, i.e. the data with the adding time between the times of first loading the data, is the original data, i.e. the adding time identifier corresponding to each original data is before the first loading time identifier. And the newly added data in the database in the browsing process is dispatched outside the original data according to the adding time mark, so that the influence of the newly added data in the database in the browsing process on the browsing process is avoided.
S203: and acquiring a page-down instruction.
This step is substantially the same as S103 in the above embodiment of the present invention, and for details, reference is made to the above embodiment of the present invention, which is not repeated herein.
S204: and loading data on the page to be inquired based on the original data according to the downward page turning instruction.
In this step, data is loaded on the page to be queried based on the original data range determined in S202 according to the page down instruction, and the specific loading process may refer to the prior art and is not described herein again. It should be noted that, in the embodiment of the present invention, the newly added data is not counted as the loaded data, and the loaded data specifically belongs to a part of the original data that has been locked. It is also emphasized that, when the amount to be supplemented is calculated in S209 described below, data outside the above-described original data range in the database is not counted.
S205: when a first page loading instruction is obtained, updating the time of loading data for the first time in the browsing process to the current time of loading the first page data, and taking the data with the added time mark before the updated time of loading the data for the first time as the original data to update the original data.
When a user wants to load data of a first page, a first page load instruction is input. In this step, when the first page loading instruction is obtained, firstly, the time for loading the data for the first time in the browsing process, that is, the first loading time identifier is updated to the time for loading the first page data at present, that is, the current time; and meanwhile, according to the adding time mark of each data, using the data before the time of the updated first loading data in the database as the original data, namely using the data added before the updated first loading time mark in the database as the original data, so as to realize the updating of the original data.
S206: after updating the original data, the first page data is loaded according to a first page load instruction.
In this step, after the original data is updated, the first page data is loaded according to the first page loading instruction, so that the data added in the database in the last browsing process can be loaded in the first page.
Before S205, the following steps may be further included: and reminding the user of new data addition on the current page. That is, in this step, after the obtained data deletion information is received in the browsing process, this step may be specifically executed, that is, when there is data addition in the browsing process, the user may be prompted to have new data addition on the current page, and specifically, the user may be prompted in a pop-up window or pop-up bubble manner.
S207: and acquiring data deletion information.
S208: and determining the deleted quantity of the loaded data in the browsing process according to the deletion time identifier and the deletion position information, and recording the deleted quantity as the quantity to be supplemented.
S209: and re-acquiring the data required to be displayed on the current page according to the page-down instruction, and selecting the data with the quantity equal to the quantity to be supplemented from back to front as the data to be supplemented.
S210: and filling the data to be supplemented to the front end of the page to be queried, and continuously loading the data on the page to be queried according to the page-down instruction.
S207 to S210 are substantially the same as S101 to S102 and S104 to S105 in the above embodiments, and for details, reference is made to the above embodiments and no further description is given here.
Specifically, in the embodiment of the present invention, the method may further include: and when the length of the screen occupied by the data deleted from the current page to the data not displayed on the current page is less than a first threshold value, loading a preset amount of data at the tail of the current page according to the sequence of the data.
Specifically, in the embodiment of the present invention, the user may also delete part of the data in the current page.
