How does Vue encapsulate components? What is the specific implementation of Vue encapsulated components? Here I will share with you how to encapsulate the tab switching component in Vue. Let's take a look at the specific code implementation.
Requirements
Simplified Version
The tab corresponding to tab is just ordinary text and is mostly used for display components.Complex version
The tab corresponding to tab includes tables, buttons, icons, forms and other elements, including data interaction, communication with parent components, etc.Performance Optimization
Cache components when switching tabs.
Proposal
Prop
Parent component passes parameters to child component.
tabList (tabs title list), tabIndex (current tab number)Custom events
Switch tab eventslot
Content distributionDynamic components
keep-alive: If you keep the switched component in memory, you can retain its state or avoid re-rendering
Complication
If it is the first requirement , you don’t have to write components yourself, the existing functions in the UI framework can fully meet your needs.
If it is the second requirement, there is generally no completely suitable UI component, and this example is my personal solution.
Encapsulate the public part of tabs
The content area corresponding to the tab uses slot content distribution
ajax Operations such as requesting data are performed in the distribution content component.
Hook function activated
Monitor whether the component is activated through activated.
