Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a flowchart of steps of a list loading method according to an embodiment of the present invention, where the method may include:
In the embodiment of the present invention, the data to be displayed is data loaded from the general list data of the background server to the cache by the browser, and is used for rendering a browser page to display a pull-down list. In order to enable a user to obtain better browsing experience, data before or after the currently displayed first visible data can be loaded into the data to be displayed from the total list data in advance, so that the loading time of displaying the required content after the user sends a scrolling instruction is reduced, the required data is displayed more quickly, and the user experience is improved. It is understood that the first visible data is a part of the data to be presented, and the data to be presented may include, in addition to the first visible data, partial data between and/or after the first visible data in the pre-loaded general list data. In practical application, the data size which can be displayed on the browser page is taken as a preset number, and when the first visible data is loaded and displayed, the data of the preset number before and/or after the first visible data in the total list data can be loaded in advance to obtain the data to be displayed.
And 102, when a list rolling instruction is detected, loading newly-added data to the data to be displayed from the total list data according to the list rolling instruction, and deleting redundant data in the data to be displayed.
In the embodiment of the present invention, in a manner before and/or after the currently displayed first visible data is loaded from the total list data in advance, although the loading time required for page scrolling may be reduced, when the amount of data to be browsed is too large, a large amount of list data which is temporarily unused may appear in the browser cache, resulting in too large cache pressure, so that the pull-down list in the browser page may be scrolled to be stuck. Therefore, the data to be displayed needs to be dynamically updated according to the received scrolling instruction, so as to reduce the cache pressure of the browser, thereby avoiding the problem of stuck down list in the browser page. The newly added data can be dynamically loaded to the data to be displayed according to the list rolling instruction, so that the browsing experience of a user is guaranteed, and meanwhile, redundant data opposite to the direction corresponding to the list rolling instruction is dynamically deleted according to the list rolling instruction.
In practical application, the data volume of the total list data can be set as N, the data volume that can be displayed on the browser page is M, and the number of downward scrolling times is K.
When N is less than or equal to M, the browser page can display all the general list data;
when N is larger than M, 2M list data can exist in the data to be displayed, when a user sends a list rolling instruction to a downward rolling roller, the data of M + 1-2M are displayed in a browser page, at the moment, 2M + 1-3M of newly added data are loaded to the data to be displayed from the total list data, and K is automatically increased by 1;
when a user sends a list rolling instruction to the downward rolling roller again, the browser page displays 2M + 1-3M data, at the moment, the redundant data of the previous 1-M are deleted from the data to be displayed, meanwhile, 3M + 1-4M newly added data are loaded into the data to be displayed from the total list data, K is automatically increased by 1, and so on;
on the contrary, when M + 1-4M data exists in the data to be displayed and the browser page currently displays 2M + 1-3M data, a user sends a list rolling instruction to an upward rolling roller wheel, the M + 1-2M data is displayed, 1-M newly added data is loaded to the data to be displayed from the total list data, and 3M + 1-4M redundant data is deleted.
And 103, displaying second visible data in the changed data to be displayed according to the list scrolling instruction, wherein the second visible data is before or after the first visible data.
In the embodiment of the present invention, a user may send a list scroll instruction for a displayed pull-down list to a browser by scrolling a scroll wheel up or down, and the browser may switch a first visual data displayed in a current browser page to a second visual data before or after the first visual data according to the number and direction of times the list scroll instruction is scrolled. It is conceivable that the second visible data may be the same amount of data as that contained in the first visible data.
The invention provides a list loading method, which comprises the following steps: displaying first visible data in the data to be displayed; when a list rolling instruction is detected, loading newly-added data to the data to be displayed from total list data according to the list rolling instruction, and deleting redundant data in the data to be displayed; and displaying second visible data in the changed data to be displayed according to the list scrolling instruction, wherein the second visible data is before or after the first visible data. When the pull-down list is rolled, the newly added data are loaded to the data to be displayed in advance, and the corresponding redundant data in the data to be displayed are deleted, so that the real-time performance of loading the data in the pull-down list is improved, and the cache pressure of the browser for storing the data to be displayed is reduced.
Fig. 2 is a flowchart of steps of another list loading method provided in an embodiment of the present invention, where the method may include:
In the embodiment of the present invention, a user may use a peripheral to which a terminal device is connected, for example: the system comprises a mouse, a keyboard and a browser, wherein a list scrolling instruction aiming at a pull-down list displayed on a browser page is sent to the browser, and the list scrolling instruction can comprise a forward identifier or a reverse identifier because the pull-down list usually has the characteristic of scrolling up and down.
In general, a pull-down list displayed in a browser page starts from a start position of total list data, and in this case, since first visible data in the total list data is empty before, it is not necessary to load data before the first visible data that needs to be currently displayed into data to be displayed, and only a first amount of data after the first visible data needs to be loaded, where the first data may be the same as the first visible data in amount, or may be configured according to browser cache needs.
If the data to be displayed is located between the starting position and the ending position of the total list data, list data with a certain data volume exists before or after the data to be displayed, and because the list scrolling instruction comprises a forward identifier, a first amount of newly added data after the data to be displayed can be correspondingly loaded into the data to be displayed from the total list data, so that the list data can be loaded in advance for being displayed by a browser page. And when the newly added data is loaded, deleting the corresponding first amount of redundant data from the data to be displayed so as to keep the data amount of the data to be displayed unchanged, thereby reducing the cache pressure of the browser. The redundant data refers to data at the reverse tail-end position in the data to be displayed corresponding to the forward identification.
In the embodiment of the present invention, if the drop-down list displayed in the browser page starts from the end position of the total list data, since the first visible data in the total list data is empty, only the second amount of data before the first visible data needs to be loaded. When the list scrolling instruction comprises the reverse identifier, a second amount of newly added data before the data to be displayed can be correspondingly loaded from the total list data into the data to be displayed, so that the list data is loaded in advance for being displayed by the browser page. And when the newly added data is loaded, deleting a second amount of corresponding redundant data from the data to be displayed so as to keep the data volume of the data to be displayed unchanged, thereby reducing the cache pressure of the browser. The redundant data refers to the data of the forward most initial position in the data to be displayed corresponding to the reverse identifier.
In the embodiment of the invention, after the browser is initially loaded to the data to be displayed from the background server of the website, the data to be displayed is analyzed, and the first visible data in the data to be displayed is utilized to render the browser page so as to display the first visible data.
In the embodiment of the invention, a user can send a list scrolling instruction to the browser by scrolling the scroll wheel on the mouse connected with the terminal equipment, the scrolling can be performed with upward or downward scroll operation for a plurality of times, the number of scrolling times is corresponding to the number of scrolling times, and the browser can scroll the displayed pull-down list according to the number of scrolling times.
And step 205, when the rolling frequency does not exceed the rolling frequency threshold, loading newly added data to the data to be displayed from the total list data according to the rolling frequency, and deleting redundant data in the data to be displayed.
In this embodiment of the present invention, the threshold of the scroll time is determined according to the data size of the total list data, and the data size of the drop-down list scroll corresponding to the scroll time cannot exceed the data size of the total list data. It is understood that each scroll time corresponds to the amount of data that needs to be scrolled by the drop-down list, and the threshold scroll time may be the data amount of the total list data divided by the data amount corresponding to one scroll time and rounded.
And determining the target data volume of a pull-down list needing to be rolled in the browser page according to the rolling times, loading newly added data of the target data volume before or after the data to be displayed to the data to be displayed from the total list data, and deleting redundant data of the target data volume in the opposite direction in the data to be displayed.
And step 206, deleting redundant data in the data to be displayed when the rolling times exceed a rolling time threshold value.
In the embodiment of the invention, when the rolling frequency exceeds the rolling frequency threshold value, only the redundant data in the data to be displayed is deleted, and the loading of the newly added data from the total list data is stopped, so that the data to be displayed cannot have the condition of empty data, thereby avoiding the empty data from appearing in the pull-down list displayed on the browser page and further improving the user experience.
Optionally, the list scrolling instruction includes: forward identification or reverse identification;
In the embodiment of the present invention, the scroll number corresponds to a preset number of offset numbers, and each scroll may cause a pull-down list displayed on a browser page to correspond to list data of the offset numbers. The third number may be derived from a multiplier equal to the offset number and the scroll number.
In an embodiment of the present invention, it is determined that the user needs to forward shift the drop down list by a third amount of data based on the list scroll instruction. And after determining that a third amount of first visible sub data exists in the data to be displayed after the first visible data, forming the first visible sub data and a fourth amount of data before the first visible data into second visible data, wherein the third amount and the fourth amount are equal to a preset amount.
It is understood that the amount of data of the drop-down list that can be displayed on the browser page is a certain amount, i.e., a preset amount, and in order to maintain the smoothness of list scrolling when the drop-down list is scrolled, the data is usually scrolled and shifted one by one, and the entire page is not switched. Therefore, the second visible data after offset is generally composed of a third amount of list data that needs to be offset, i.e., the first visible sub data, and a portion of data at the end position of the first visible data, i.e., the fourth amount of data, and the sum of the third amount and the fourth amount is equal to a preset amount. Further, when the third number is smaller than the preset number, the fourth number is larger than zero, which is the above condition; and when the third number is greater than or equal to the preset number, the fourth number is less than or equal to zero, and the second visible data needs to maintain the preset number, so that the fourth number of data needs to be removed from the starting position in the third number of the first visible sub data to obtain the preset number of the second visible data. For example: if (A, B, C, D, E, F, G, H) to be displayed exists, the preset number is 2, the first visible data is (D, E), and the third number is 1, then the second visible subdata (E, F) is formed by the third number of first visible subdata F after the first visible data (D, E) and the fourth number of E before the first visible subdata of 1.
In the embodiment of the present invention, on the contrary, the shifted second visible data is composed of a third number of list data that needs to be shifted, that is, the first visible sub data, and a part of data of the start position of the first visible data, that is, the fourth number of data, and the sum of the third number and the fourth number is equal to the preset number. For example: if (B, C, D, E, F, G) to be displayed exists, the preset number is 2, the first visible data is (D, E), the third number is 1, and then the second visible subdata (C, D) is formed by the first visible subdata C with the third number before the first visible data (D, E) and the D with the fourth number before the first visible subdata with the fourth number being 1.
In this embodiment of the present invention, if the list scrolling command includes a forward flag, and there is no data of a third quantity that needs to be shifted after the first visible data in the data to be displayed, and there is at most a fifth quantity of second visible sub data, the second visible data may be composed of the second visible sub data and data of a sixth quantity before the second visible sub data, and the fifth quantity and the sixth quantity are equal to a preset quantity after the second visible data, so as to keep the quantity of data displayed by the second visible data unchanged. For example: the data (B, C, D, E, F, G) to be displayed exist, the preset number is 2, the first visible data is (D, E), the third number is 3, only the fifth number of second visible sub-data (F, G) exists after the first visible data, and the second visible data (F, G) is formed by the second visible sub-data and the previous sixth number of 0 data.
In this embodiment of the present invention, if the list scrolling command includes a reverse identifier, and when there is no third-order data that needs to be shifted in the data to be displayed before the first visible data, and there is at most a fifth amount of second visible sub data, the second visible data may be composed of the second visible sub data and a sixth amount of data before the second visible sub data, and the fifth amount and the sixth amount are equal to a preset amount later, so as to keep the amount of data displayed by the second visible data unchanged. For example: the data (B, C, D, E, F, G) to be displayed exist, the preset number is 2, the first visible data is (D, E), the third number is 3, only the fifth number of second visible data (B, C) exists before the first visible data, and the second visible data (B, C) is formed by the second visible data and the sixth number of data (0) after the second visible data.
The invention provides a list loading method, which comprises the following steps: displaying first visible data in the data to be displayed; when a list rolling instruction is detected, loading newly-added data to the data to be displayed from total list data according to the list rolling instruction, and deleting redundant data in the data to be displayed; and displaying second visible data in the changed data to be displayed according to the list scrolling instruction, wherein the second visible data is before or after the first visible data. When the pull-down list is rolled, the newly added data are loaded to the data to be displayed in advance, and the corresponding redundant data in the data to be displayed are deleted, so that the real-time performance of loading the data in the pull-down list is improved, and the cache pressure of the browser for storing the data to be displayed is reduced.
