Vue and Element-UI cascade drop-down box emit usage
Article Introduction：The Element-UI cascading drop-down box realizes parent-child component communication through custom events: the parent component listens to the change event issued by the child component and obtains the selection result. The handleChange method is used to handle selection logic and can perform different operations based on hierarchical differences. In order to obtain intermediate process information, you need to customize events inside the cascading selection box, and one event is triggered at each selection level. For large data sets, it is necessary to optimize the data loading method and use packaging components for complex logic processing. Code readability and maintainability cannot be ignored, and clear naming and annotation can help with post-maintenance.
