[0034] In order to have a clearer understanding of the technical features, objects and effects of the application, the specific embodiments of the application will be described in detail with reference to the drawings.

[0035] In a preferred embodiment, with reference to Figure 1 The drop-down selection box inventory quantity display method of the embodiment comprises the following steps:

[0036] Step S1, the server receives the product name inputted in the search box of the browser in the user terminal.

[0037] Specifically, the browser is installed on the user terminal, and the user can access the corresponding server through the browser. The server stores various information of the products, including the product name and the real-time inventory quantity of the products. When the user wants to query the inventory of the products, the user inputs the product name that the user wants to query in the search box of the browser in the terminal. At this time, the browser accesses the corresponding server, and transmits the product name inputted by the user to the server. The server receives the product name that the user wants to query.

[0038] Step S2, find the first real-time inventory quantity corresponding to the product name.

[0039] Specifically, after the server receives the product name that the user wants to query, the various product names in the database are matched with the received product name. If the product name in the database is the same as the received product name, the product name in the database is selected, and the first real-time inventory quantity corresponding to the product name is found.

[0040] Step S3, send the first real-time inventory quantity and the corresponding product name to the user terminal.

[0041] Specifically, after the product name in the database that matches the product name received by the server is found, and the first real-time inventory quantity corresponding to the product name in the database is found, the first real-time inventory quantity and the corresponding product name are sent to the user terminal.

[0042] Alternatively, if the product name in the database that is the same as the product name received by the server is not found, it is possible that the user input is incorrect, and the returned is empty data, and a blank page is displayed in the drop-down box.

[0043] Step S4, display the product name and the corresponding first real-time inventory quantity in the drop-down box of the search box.

[0044] Specifically, after the corresponding product name and the first real-time inventory quantity corresponding to the product name are received by the browser in the user terminal, the product name and the corresponding first real-time inventory quantity are displayed in the drop-down box of the search box at the same time.

[0045] Alternatively, the first real-time inventory quantity can be displayed below, above, left or right of the corresponding product name.

[0046] By implementing this embodiment, when querying product inventory, the product name and corresponding real-time inventory can be displayed simultaneously in the drop-down selection box in one step. There is no need to search for the corresponding product first and then search for the first inventory quantity of the product. This can reduce the number of operation steps and time for users, allow them to know the real-time status of product inventory in a timely manner, and facilitate various subsequent operations, thereby improving the timeliness of subsequent operations.

[0047] In a preferred embodiment, reference Figure 2 The drop-down selection box inventory quantity display method in this embodiment further includes the following step after step S3:

[0048] Step S31: Store the first real-time inventory quantity and the corresponding product name to the user terminal.

[0049] Specifically, after finding a product name and corresponding first real-time inventory quantity that match the product name received by the server in the database, this product name and corresponding first real-time inventory quantity are sent to the user terminal and stored. If the user searches for the first real-time inventory quantity of the same product again in the browser, the latest first real-time inventory quantity found by the server is returned to the user terminal, replacing the previous first real-time inventory quantity for this product, ensuring that the first real-time inventory quantity of this product stored on the user terminal is always up-to-date.

[0050] The drop-down selection box inventory quantity display method in this embodiment can store server data on the user terminal, back it up, and update it in a timely manner to prevent unforeseen circumstances.

[0051] In a preferred embodiment, reference Figure 3 In this embodiment of the drop-down selection box inventory quantity display method, if the server response is abnormal in step S2 when step S1 is executed again, the real-time inventory quantity corresponding to the product name is searched in the user terminal, and step S4 is executed.

[0052] Specifically, when searching for a product name and its corresponding first real-time inventory quantity, if the server response is abnormal, such as an interface error between the user terminal and the server, server inability to respond, or excessively long server response time, causing the user terminal to not receive the corresponding product name and its corresponding first real-time inventory quantity, the user terminal will directly compare the product name entered by the user in the search box with all product names stored in the user terminal's database. If the product name stored in the user terminal's database is the same as the product name the user is looking for, then the same product name and its corresponding first real-time inventory quantity will be displayed in the drop-down box of the search box.

[0053] By implementing this embodiment, when the server experiences a response error, the user does not have to wait for the first real-time inventory quantity to be displayed. Instead, the user can refer to the first real-time inventory quantity stored on the user's terminal during the last search. This ensures a good user experience and improves the user's processing efficiency.

[0054] In a preferred embodiment, reference Figure 4 and Figure 5 The method for displaying inventory quantity in a drop-down selection box in this embodiment includes the following steps:

[0055] Step S11: The server receives the product name entered in the search box of the browser on the user's terminal.

[0056] Specifically, when a user wants to check the inventory of a product, they enter the name of the product they want to search for in the search box of their terminal browser. The server then receives the product name that the user wants to query. For example, if a user wants to find the inventory quantity of rock sugar pear, the user enters the name "rock sugar pear" in the search box, and the server then receives the name "rock sugar pear".

[0057] Step S12: Find the first real-time inventory quantity corresponding to the product name, and find the second real-time inventory quantity corresponding to the related product names.

[0058] Specifically, when the server receives the product name requested by the user, it splits the product name into several related product names according to preset rules. Then, it matches the various product names in the database with the received product name and all the split related product names. If a product name in the database matches the received product name, that product name is selected from the database, and the corresponding first real-time inventory quantity is found. If a product name in the database matches one or more of the split related product names, that product name is selected from the database, and the corresponding second real-time inventory quantity is found. For example, after the server receives "rock sugar pear," it splits "rock sugar pear" into "rock sugar" and "pear" according to preset rules. Then, it matches "rock sugar pear," "rock sugar," and "pear" with various product names in the server. It selects the product names that match "rock sugar pear," "rock sugar," and "pear," and then finds the first real-time inventory quantity for "rock sugar pear" and the second real-time inventory quantity for "rock sugar" and "pear," respectively. Finally, the found first real-time inventory quantity for "rock sugar pear" is 555, the second real-time inventory quantity for "rock sugar" is 333, and the second real-time inventory quantity for "pear" is 234. Finally, the names of rock sugar pears and their corresponding first real-time inventory quantities, as well as the names of rock sugar and pears and their corresponding second real-time inventory quantities, are displayed in the drop-down menu of the search box.

[0059] Alternatively, the product names received by the server can be compared with the product names in the server database. A corresponding matching degree can be added to each product name in the database according to preset rules. The matching degrees can be ranked, and the relevant product names corresponding to the top preset number of matching degrees can be selected. Then, all the selected relevant product names and their corresponding second real-time inventory quantities can be sent to the user terminal.

[0060] Step S13: Send the first real-time inventory quantity and the corresponding product name, as well as the relevant product name and the corresponding second real-time inventory quantity, to the user terminal.

[0061] Specifically, the found product name and corresponding first real-time inventory quantity, as well as the found related product name and corresponding second real-time inventory quantity, are sent to the user terminal.

[0062] Alternatively, if no matching or related product names are found in the database, it may indicate that the user entered the wrong information, and empty data will be returned, with a blank page displayed in the drop-down list.

[0063] Step S14: Display the product name and corresponding first real-time inventory quantity in the drop-down box of the search box, and display the related product name and corresponding second real-time inventory quantity.

[0064] Specifically, after finding the same product name and corresponding first real-time inventory quantity in the database, as well as the related product name and corresponding second real-time inventory quantity, the product name and corresponding first real-time inventory quantity, along with the related product name and corresponding second real-time inventory quantity, are sent to the user terminal and simultaneously displayed in the drop-down box of the search box.

[0065] Alternatively, the first real-time inventory quantity can be displayed below, above, to the left, or to the right of the corresponding product name; the second real-time inventory quantity can also be displayed below, above, to the left, or to the right of the corresponding product name. For a neater and more aesthetically pleasing appearance, the display format of the first real-time inventory quantity and its corresponding product name can be kept consistent with the display format of the second real-time inventory quantity and its corresponding related product name.

[0066] By implementing this embodiment, users only need to enter part of the product name to find the desired product and its corresponding real-time inventory quantity, which is especially advantageous when the product name is long. Furthermore, displaying similar product names and their corresponding real-time inventory quantities facilitates comparison or other needs, further improving the user experience and saving time spent entering product names.

[0067] In a preferred embodiment, the drop-down selection box inventory quantity display method of this embodiment further includes the following steps after sending the relevant product name and the corresponding second real-time inventory quantity to the user terminal:

[0068] Step S32: Store the first real-time inventory quantity and the corresponding product name, as well as the relevant product name and the corresponding second real-time inventory quantity, to the user terminal.

[0069] Specifically, after finding a product name and its corresponding first real-time inventory quantity that matches the product name received by the server, as well as related product names and their corresponding second real-time inventory quantities, in the database, this product name and its corresponding first real-time inventory quantity, along with related product names and their corresponding second real-time inventory quantities, are sent to the user's terminal and stored. If the user searches for the first real-time inventory quantity of the same product again in the browser, the latest first and second real-time inventory quantities found by the server are returned to the user's terminal, replacing the previous first and second real-time inventory quantities for this product name and related product names, ensuring that the first and second real-time inventory quantities for this product name stored on the user's terminal are always up-to-date.

[0070] The drop-down selection box inventory quantity display method in this embodiment can store server data on the user terminal, back it up, and update it in a timely manner to prevent unforeseen circumstances.

[0071] In a preferred embodiment, the drop-down selection box inventory quantity display method of this embodiment displays an icon, pattern, or animated pattern on the browser to indicate that the system is querying and please wait when searching for the first real-time inventory quantity in step S2.

[0072] Specifically, when a user enters the name of the product they want to search for and clicks the search trigger button, an icon, pattern, or animated graphic will be immediately displayed on the browser to indicate that the system is searching and please wait.

[0073] Alternatively, you could make the icons, patterns, or animated graphics more interesting, or display some mini-games that allow users to interact with them.

[0074] This embodiment is even more effective in situations with network latency and slow internet speed, allowing users to know in a timely manner that a query is in progress, and reducing the boredom of waiting users through attractive and interesting patterns, animated patterns, or mini-games.

[0075] In a preferred embodiment, the display of the first real-time inventory quantity in the drop-down selection box inventory quantity display method of this embodiment is implemented by using a stacked style sheet based on the Ant Design select drop-down box component.

[0076] Specifically, after the product name and corresponding initial real-time inventory quantity are sent to the user terminal, the user terminal uses Cascading Style Sheets (CSS) on top of the Ant Design select dropdown component to display the initial real-time inventory quantity, and also displays the product name corresponding to the initial real-time inventory quantity using the Ant Design select dropdown component. The technology stack used is React + Ant Design + CSS. It primarily utilizes the CSS `content` property and the `attr()` function. The `content` property is used in conjunction with the `:before` and `:after` pseudo-elements to insert generated content, and the `attr()` function inserts variable values ​​and inventory information to display the product name and corresponding real-time inventory quantity.

[0077] This embodiment uses Ant Design's select dropdown component to simultaneously display the product name and the corresponding first real-time inventory quantity. It expands upon the original display method without affecting the original functionality, while meeting user needs and making the display steps and process more convenient and concise.

[0078] In a preferred embodiment, the apparatus for displaying inventory quantity in a drop-down selection box according to this embodiment includes:

The browser then accesses the corresponding server, sends the product name entered by the user to the server, and the server receives the product name that the user wants to query.

[0081] The search unit is used to find the first real-time inventory quantity corresponding to the product name.

[0082] Specifically, when the server receives the product name that the user wants to query, it matches the various product names in the database with the received product name. If the product name in the database is the same as the received product name, then the product name in the database is selected, and then the first real-time inventory quantity corresponding to this name is found.
