In this embodiment, in the step S11, the device 1 acquires multiple lists to be shuffled, wherein, in the multiple lists to be shuffled, each list to be shuffled includes several data elements, and At least two data elements of the to-be-shuffled list have different attribute information.

For example, an e-commerce company needs to design the display of products on the Web page according to the operation strategy and packaging display rules. The product data package corresponding to the product is stored in the back-end product list. A product list to be shuffled contains several product elements with the same attribute information. For example, the product list L1 contains n ordinary e-commerce product data {a1, a2, a3, ...,an}, the product list L2 contains m second-hand excellent product data {b1,b2,b3,...,bm}, the product list L3 contains k special product data {c1,c2,c3,...,ck} .

Preferably, the attribute information includes at least any one of the following:

type of data;

Data Format;

data structure.

For example, e-commerce commodities usually include common e-commerce commodities, spare parts warehouse commodities, second-hand premium products, advertising commodities, special offer commodities, etc. The attribute information of commodity data corresponding to the commodities also includes, but is not limited to, data format, structure, commodity Price, quantity of items in stock, etc.

Continuing in this embodiment, in the step S12, the device 1 acquires data elements from a plurality of lists to be shuffled according to a preset rule, so as to determine each data element of the shuffled list.

For example, an e-commerce company needs to display products with different attributes on the Web page according to the operation strategy and packaging display rules, etc., then the product data corresponding to the product is stored in different product lists, and the front-end Web page can be accessed on the Web page according to the designed rules. The product list interface corresponding to the product to be displayed on the page, obtains the corresponding product with different attributes, and outputs it to the Web page after packaging. For example, the list corresponding to the product that needs to be displayed on the web page is L, and the list L contains 8 product data elements {a1, a2, b1, b2, b3, a3, c2, c3}. These 8 product data elements are based on preset Good rules, taken from lists L1, L2 and L3 respectively.

Preferably, wherein, the preset rules include:

A placeholder rule, wherein the placeholder rule is used to determine the placeholder code of each data element in the shuffled list;

A source rule, wherein the source rule is used to determine the source of each data element in the shuffled list.

For example, the list corresponding to the products displayed on the Web page is L, and the list L contains 8 commodity data elements {a1, a2, b1, b2, b3, a3, c1, c2}, and these 8 commodity data elements are based on preset Placeholder rules and source rules, obtained from lists L1, L2, and L3, respectively.

Preferably, wherein, based on the preset rule and the to-be-shuffled list, determining that each data element of the shuffled list includes:

Based on the placeholder rule, it is determined that each data element of the shuffled list comes from the corresponding list to be shuffled;

Based on the source rule, the corresponding data element is obtained from the corresponding to-be-shuffled list to determine each data element of the shuffled list.

In an application scenario based on java or other programming codes, the placeholder rule can be defined as an array, and each element in the array identifies the placeholder code at the corresponding position in the list L, that is, the data element at the corresponding position in the list L is from Which of the lists L1, L2, and L3 is obtained from, for example, if the placeholder code array corresponding to list L is designed as (1,1,2,2,2,1,3,3), then the first place in list L The data elements corresponding to the three positions of , 2 and 6 come from the list L1, the data elements corresponding to the 3rd, 4th, and 5th positions in the list L come from the list L2, and the 7th and 8th positions in the list L correspond to the two positions. The data elements are from list L3.

In the application scenario based on java or other programming code, the source rule can also be defined as an array, and each element in the array identifies the source of the corresponding position in the list L, that is, the data element in the corresponding position in the list L is based on the placeholder The data element corresponding to the position in the list determined by the code. For example, if the source array corresponding to list L is designed as (1, 2, 1, 2, 3, 3, 1, 2), then the placeholder code array determines which list the data elements corresponding to each position in list L come from. Each data element in the list L can be further determined: the data element corresponding to the first position is the first data element a1 in the list L1, the data element corresponding to the second position is the second data element a2 in the list L1, the third The data element corresponding to the first position is the first data element b1 in the list L2, the data element corresponding to the fourth position is the second data element b2 in the list L2, and the data element corresponding to the fifth position is the third data element in the list L2. data element b3, the data element corresponding to the sixth position is the third data element a3 in the list L1, the data element corresponding to the seventh position is the first data element c1 in the list L3, and the data corresponding to the eighth position The element is the second data element c2 in list L2.

Preferably, if the corresponding data element obtained from the corresponding to-be-shuffled list based on the source rule does not exist or is empty, the preset data element is determined as the corresponding data element in the shuffled list.

For example, in the above embodiment, if the list L2 contains only two data elements, according to the preset rule, the data element corresponding to the fifth position in the list L is the third data element in the list L2, and the data element does not exist , then the data element corresponding to the fifth position in the list L is a preset data element, such as the data element A corresponding to a special offer; or if the third data element in the list L2 corresponds to an empty data element, according to the preset Rule, the data element corresponding to the 5th position in the list L is the 3rd data element in the list L2, but the data element is an empty data element, then the data element corresponding to the 5th position in the list L is also a preset data element, For example, the data element A corresponding to a special offer. In this way, the data elements are optimized, and a complete shuffled list can be obtained even if the data elements are incomplete.

Continuing in this embodiment, in the step S13, the device 1 sequentially assembles each data element obtained from the to-be-shuffled list according to the preset rule to form a shuffled list, so as to realize multiple to-be-shuffled lists Data elements are shuffled.

For example, in an application scenario based on java or other programming code, according to the preset placeholder code array (1,1,2,2,2,1,3,3) and source array (1,2,1,2 ,3,3,1,2), determine the data elements corresponding to each position of the list L after shuffling: the data element corresponding to the first position is the first data element a1 in the list L1, and the second position corresponds to The data element is the second data element a2 in the list L1, the data element corresponding to the third position is the first data element b1 in the list L2, and the data element corresponding to the fourth position is the second data element b2 in the list L2 , the data element corresponding to the fifth position is the third data element b3 in the list L2, the data element corresponding to the sixth position is the third data element a3 in the list L1, and the data element corresponding to the seventh position is the list L3 The first data element c1, the data element corresponding to the eighth position is the second data element c2 in the list L2, and the obtained eight data elements are assembled in sequence to form a shuffled list L as {a1, a2, b1,b2,b3,a3,c1,c2}. If the third data element in the list L2 does not exist or is an empty data element, then the data element corresponding to the fifth position in the list L is the preset data element A, and the optimized complete mixture is obtained in the case of incomplete data elements. The permutation table L is {a1,a2,b1,b2,A,a3,c1,c2}.

Preferably, wherein the sequential assembling of each of the data elements to form a shuffled list, so as to realize the shuffling of the data elements of a plurality of lists to be shuffled, includes:

Judging whether there is repetition in each of the data elements, if there is, only the data element that appears first in order is retained, and other repeated data elements are replaced with preset data elements to optimize the data elements of the shuffled list;

Each optimized data element is sequentially assembled to form a shuffled list, so as to realize shuffling of data elements of multiple lists to be shuffled.

For example, in an application scenario based on java or other programming code, according to the preset placeholder code array (1,1,2,2,2,1,3,3) and source array (1,2,1,2 ,3,3,1,2), determine the data elements corresponding to each position of the list L after shuffling: the data element corresponding to the first position is the first data element a1 in the list L1, and the second position corresponds to The data element is the second data element a2 in the list L1, the data element corresponding to the third position is the first data element b1 in the list L2, and the data element corresponding to the fourth position is the second data element b2 in the list L2 , the data element corresponding to the fifth position is the third data element b3 in the list L2, the data element corresponding to the sixth position is the third data element a3 in the list L1, and the data element corresponding to the seventh position is the list L3 The first data element c1, the data element corresponding to the eighth position is the second data element c2 in the list L2. Compare all the 8 data elements obtained, or when obtaining the data element corresponding to a certain position, compare it with the obtained data element, for example, if a2 is the same as c1, that is, the second item in the list L after shuffling If the data element a2 corresponding to the position and the data element c1 corresponding to the seventh position are repeated, only the data element a2 corresponding to the second position is retained, and the data element corresponding to the seventh position is replaced with the preset data element A to achieve Data elements are optimized, and then each optimized data element is sequentially assembled to form a shuffled list L as {a1, a2, b1, b2, a3, a3, A, c2}.

Preferably, the method for shuffling list data elements further includes:

Responding to the page display calling instruction and returning the shuffled list, so as to realize page display of the shuffled list data elements.

For example, in an application scenario based on java or other programming code, it is necessary to display different types of products on the web page. After triggering the web page link, the web page sends a page display call instruction to the background, and the background receives the page display call instruction. Then, based on the preset rules, the data elements corresponding to the products are obtained from different types of lists. After shuffling, the shuffled list corresponding to the products displayed on the Web page is obtained, and the shuffled list corresponding to the products is returned through the list interface. After rendering and then displayed on the web page.

Preferably, the method for shuffling list data elements further includes:

Responding to a background list management calling instruction and returning the shuffled list to implement background list management.

For example, in an application scenario based on java or other programming code, it is necessary to call a shuffled list with different attributes of the corresponding data elements of the product as the to-be-shuffled list for shuffling of other lists or other management requirements, then in the background After receiving the list management calling instruction, return the corresponding shuffled list to meet the shuffling or management requirements of other lists.
