The role of @component in Vue
In Vue, the @component
directive is used to dynamically instantiate a component and place it in the template presented in. It provides the flexibility to create and destroy components at runtime.
Purpose
@component
The directive is usually used in the following situations:
- Dynamic loading of components: Allows dynamic loading and rendering of components based on data or user input.
- Create reusable components: It is possible to create reusable components and use them in different templates without explicit import or registration.
- Improve the modularity and maintainability of the code: Separate component definition from its instantiation, making the code easier to organize and maintain.
Usage
@component
The syntax of the command is as follows:
<code><@component :is="componentName" /></code>
Among them:
## The- #:is
attribute specifies the name of the component to be instantiated. It can be a dynamic value, determined by data or user input.
The component name can be a registered global component, a local component, or a component introduced through - import
.
Advantages
Using the@component directive has the following advantages:
- Flexibility :Allows dynamic creation and destruction of components at runtime.
- Modularization: Separate component definition from its instantiation.
- Code reuse: You can create reusable components to improve code efficiency.
Example
Suppose there is a component namedmy-component, we can use
@component in the template Instantiate it dynamically:
<template> <@component :is="componentType" /> </template> <script> export default { data() { return { componentType: 'my-component' } } } </script>
componentType can change dynamically based on data or user interaction, allowing us to dynamically load different components.

Vue multi-page development is a way to build applications using the Vue.js framework, where the application is divided into separate pages: Code Maintenance: Splitting the application into multiple pages can make the code easier to manage and maintain. Modularity: Each page can be used as a separate module for easy reuse and replacement. Simple routing: Navigation between pages can be managed through simple routing configuration. SEO Optimization: Each page has its own URL, which helps SEO.

Vue.js has four methods to return to the previous page: $router.go(-1)$router.back() uses <router-link to="/" component window.history.back(), and the method selection depends on the scene.

You can query the Vue version by using Vue Devtools to view the Vue tab in the browser's console. Use npm to run the "npm list -g vue" command.

Check the version information in the <script> tag in the HTML file that refers to the Vue file.

Function interception in Vue is a technique used to limit the number of times a function is called within a specified time period and prevent performance problems. The implementation method is: import the lodash library: import { debounce } from 'lodash'; Use the debounce function to create an intercept function: const debouncedFunction = debounce(() => { / Logical / }, 500); Call the intercept function, and the control function is called at most once in 500 milliseconds.
