This article mainly introduces in detail how Vue2 imitates Taobao to realize the three-level linkage of provinces and municipalities. It has certain reference value. Interested friends can refer to
Three-level linkage. With the More and more aesthetics are emerging, and many companies are imitating Taobao's three-level linkage, which is good-looking and fashionable, so our company is the same... In order to make it easier to post code, I separated the json of provinces and cities written in the data Come out, download and paste it to use, the link is as follows: vue.json (This is directly a data, just put it into your vue2 project. (Because my project uses vue2, so other attributes and blog content are It matches. Please cooperate with the blog to download this json)).
First the page displays as follows:
#Then there will be a three-level linkage in our county-level area, as follows: (The following is a fragment, the background color has not been intercepted)
What this picture looks like and what form it appears in depends on your company's UI needs. Our company makes it a pop-up layer. . Then the background color is transparent. In order to save traffic, I only intercepted a section. The final display is as follows:
If your company has the same needs as ours, I hope this can help you. . The following is the three-level linkage code and css style written in the vue2 project:

This completes the three-level linkage of a province and city.
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.

Java and JavaScript are different programming languages. 1.Java is a statically typed and compiled language, suitable for enterprise applications and large systems. 2. JavaScript is a dynamic type and interpreted language, mainly used for web interaction and front-end development.
