The relationship between JS and H5: H5 is the stage (structure and content) of the web page, and JS is the actor on the stage (responsible for interaction and dynamic effects). They complement each other and are indispensable: H5 provides a stage and is responsible for building web structure, content and style. JS gives web pages the ability to interact dynamically, making web pages lively and interesting in response to user operations.

To realize the secondary linkage between Vue and Element-UI, pay attention to data-driven: organize data, clarify the relationship between province and city (data structure) and dynamic updates are implemented through Vue's responsive data (data-driven view), process asynchronous data, display load status and error information (asynchronous operations and error handling), consider performance optimization, and adopt technologies such as virtual scrolling (performance optimization and best practices)

It is convenient to directly use Element-Plus' Select component nesting to achieve multi-level linkage. Although it is convenient, the efficiency is worrying.

Pay attention to details such as asynchronous operations, data consistency, error handling and loading status prompts. Code is just a tool, and what is important is design ability and performance sensitivity.

Using Element-UI's el-cascader component can facilitate three-level linkage, but data structure is the key. The best practice is to flatten arrays, each object contains value, label, and children attributes, pointing to child nodes. When loading data asynchronously, send requests to obtain the next level of data according to the selected value in the handleChange method, and update options data to ensure the integrity of the data structure. Pay attention to common errors such as confusing data structure, asynchronous data loading failures, and untimely data updates. Optimized performance can be done using virtual lists, cached data, and load on demand. Clear data structures, good code style and error handling are key, which helps avoid pitfalls and improve code maintainability.
