How to achieve multi-casual linkage between Vue3 and Element-Plus
Article Introduction：It is convenient to directly use Element-Plus' Select component nesting to achieve multi-level linkage. Although it is convenient, the efficiency is worrying. The core lies in how to efficiently manage and update data at the data layer, use recursive functions to process data, and use ref to manage the selection state. 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.

How to migrate from Vue 2 to Vue 3?
Article Introduction：When migrating Vue2 projects to Vue3, you need to pay attention to syntax differences, third-party plug-in compatibility and building tool selection. 1. Use VueCLI or Vite to upgrade the environment and ensure that Node.js version is above 14.x; 2. Note that Vue3 removes $on, $off, and $once, and the filter is replaced with calculation attributes or methods. The responsive system uses Proxy, and v-model binds modelValue by default; 3. Check whether third-party plug-ins support Vue3, and replace it with community fork or alternatives such as Pinia and VueRouterv4 if necessary; 4. Components can be gradually replaced through the vue-compat package to finally unify the code style.
