Article Introduction：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.
