Implementation method of multi-level linkage pull-down box between Vue and Element-UI
Article Introduction：How to use Element-UI in Vue to implement multi-stage linkage drop-down boxes? Use multiple El-Select components to bind data through v-model and use logic to control dynamic changes in options. Use a recursive function to efficiently generate and update the option list, dynamically update the options for subsequent drop-down boxes based on the selection results. Pay attention to the design of the data structure. A clear data structure can simplify the code logic. Considering performance issues when the data volume is large, use tree structure or virtual scrolling technology to optimize rendering. Handle errors to avoid program crashes. Pay attention to the readability and maintainability of the code, use meaningful variable names, add comments, and split the code into small, reusable functions.
