[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0038] Embodiment 1

[0039] Figure 1is a schematic diagram of a method for implementing an automatic loop infinite scrolling list according to an exemplary embodiment. Figure 1 , provides a method for realizing an automatic loop infinite scrolling list, including:

[0040] Acquire data to be displayed, and place the data to be displayed into a single circular linked list;

[0041] According to a preset minimum scroll value, a corresponding number of to-be-displayed data are cyclically taken out from the single-circular linked list every preset time, and the to-be-displayed data are placed in a preset display list;

[0042] The data to be displayed in the display list is displayed.

[0043] In specific practice, a circular singly linked list is a form of a singly linked list, and its structural feature is that the pointer field of the last node in the linked list is no longer an end mark, but points to the first node of the entire linked list, so that the linked list forms a loop. Therefore, after placing the data to be displayed into the single circular linked list, a corresponding number of data to be displayed are selected from the single circular linked list, and when the last data in the single circular linked list is looped, the first data in the single circular linked list can be looped in the next loop, thereby avoiding the operation of deleting the top of the list and then adding new data at the bottom in real time in the prior art.

[0044] The data to be displayed in the display list is displayed, and the display device can be a computer web page or any display device that can scroll and display.

[0045] It is understandable that the technical solution shown in this embodiment can obtain the data to be displayed, and place the data to be displayed in a single loop linked list; according to the preset minimum scroll value, every preset time, the corresponding number of data to be displayed is cyclically taken out from the single loop linked list, and the data to be displayed is placed in a preset display list; and the data to be displayed in the display list is displayed. It is understandable that the technical solution shown in this embodiment uses the method of single loop linked list cyclic display, which avoids frequent page redrawing and reduces the page burden. The single loop linked list display makes the page scrolling smoother and can achieve a seamless effect.

[0046] In actual application, this embodiment will pre-generate a list, called a display list, and then put the data to be displayed into a single circular linked list, and then determine whether scrolling display is required based on the set minimum scrolling number.

[0047] It should be noted that see Figure 2 , the step of cyclically taking out a corresponding number of data to be displayed from the single circular linked list according to a preset minimum scroll value includes:

[0048] Obtain the number of data to be displayed in the single circular linked list;

[0049] Comparing the number of data to be displayed with the minimum scroll value;

[0050] If the number of the data to be displayed is not greater than the minimum scroll value, all the data to be displayed are cyclically taken out from the single-circular linked list and placed into a preset display list.

[0051] In specific practice, if the number of entries with cyclic data in a single circular linked list is less than or equal to the value of the minimum scrolling number, all the data in the single circular linked list are directly assigned to the display list, so that the display device can statically display the data in the single circular linked list.

[0052] For example, there are 3 pieces of data to be displayed, all of which are placed in a single circular linked list. The minimum scrolling number that the display module can display simultaneously is 5. This proves that the display module can display 5 pieces of data at the same time, and can display all 3 pieces of data to be displayed at the same time, so it is a static display.

[0053] It should be noted that see Figure 2 , the step of cyclically taking out a corresponding number of data to be displayed from the single circular linked list according to a preset minimum scroll value includes:

[0054] Obtain the number of data to be displayed in the single circular linked list;

[0055] Comparing the number of data to be displayed with the minimum scroll value;

[0056] If the number of data to be displayed is greater than the minimum scroll value, then,

[0057] Create a head pointer and a tail pointer, the head pointer points to the first data to be displayed in the single circular linked list, and the tail pointer points to the Nth data to be displayed in the single circular linked list, N=X, X is the minimum scroll value; every preset time, the head pointer and the tail pointer traverse backwards once;

[0058] The data to be displayed pointed to by the head pointer and the tail pointer and the data to be displayed between the head pointer and the tail pointer are taken out, and placed in a preset display list.

[0059] In practice, if the number of entries in a single circular linked list is greater than the minimum scrolling number, the data in the single circular linked list is traversed through a while loop and assigned to the display list.

[0060] The specific implementation is achieved through double pointers. The head pointer headPointer points to the first data in the linked list, and the tail pointer rearPointer traverses the single-loop linked list until the minimum scrolling number is reached and stops. The display list scrolls in the visible area of ​​the page to display the data between the two pointers. After each scrolling of a piece of data, the head pointer headPointer and the tail pointer rearPointer traverse backwards once to point to the new data, and the scrolling is repeated in this way to achieve an infinite scrolling effect.

[0061] In actual application scenarios, if the value of the minimum scroll number is 5 and there are 10 data in the single circular linked list, then first, the head pointer points to the first data, the tail pointer points to the fifth data, and the display module displays the first to fifth data at the same time. After the preset time, the head pointer points to the second data, and the tail pointer points to the sixth data, then the display module displays the second to sixth data at the same time, and so on.

[0062] It should be noted that, when the head pointer or the tail pointer points to the last piece of data in the single circular linked list, after a preset time, the head pointer or the tail pointer points to the first piece of data in the single circular linked list again.

[0063] In actual application scenarios, since a single circular linked list is used, when the head pointer points to the 5th data and the tail pointer points to the 10th data, the data pointed to by the tail pointer is the last data of the single circular linked list. Then after the preset time, the head pointer points to the 6th data and the tail pointer points to the 1st data. The display module simultaneously displays the 6th to 10th data and the 1st data.

[0064] In practice, see Figure 2 , before obtaining the data to be displayed and placing the data to be displayed into the single circular linked list, it also includes:

[0065] Initialize the preset display list.

[0066] It can be understood that initializing the display list can avoid the presence of previously leftover data in the display list and avoid display anomalies.

[0067] Preferably, the above method can be integrated into an automatic looping infinite scrolling list control on a computer for ease of use.

[0072] The display module is used to display the data to be displayed in the display list.

[0073] It is understandable that the technical solution shown in this embodiment can obtain the data to be displayed through the data acquisition module, and place the data to be displayed in a single loop linked list; through the loop extraction module, according to the preset minimum scroll value, every preset time, the corresponding number of data to be displayed are cyclically taken out from the single loop linked list, and the data to be displayed is placed in a preset display list; the data to be displayed in the display list is displayed through the display module.
