This time I will show you how to use mixin in Vue, and what are the precautions when using mixin in Vue. The following is a practical case, let's take a look.
Vue provides a mixing mechanism - mixins, which is used to reuse component content more efficiently. At first I thought there was no difference between this and components. . Later I found out it was wrong. Let's take a look at the difference between mixins and imported components under normal circumstances.
After the component references, it is equivalent to opening up a separate space in the parent component to perform corresponding operations based on the values from the parent component props. In essence, the two are still distinct. relatively independent.
And mixins, after introducing the component, merge the internal content of the component such as data and other methods, method and other attributes with the corresponding content of the parent component. It is equivalent to that after the introduction, various property methods of the parent component have been expanded.
Simple component reference:
Parent component child component>>> Parent component child component
mixins:
Parent component child component> >> new parent component
Function: Multiple components can share data and methods. After being introduced in a component using mixin, the methods and properties in the mixin are also incorporated into the component, and can be directly use. Hook Function will be called both, and the hook in the mixin will be executed first.
The following is an introduction to the usage of vue mixin. The specific introduction is as follows:
1. Define a js file (mixin.js)
export default { data() { return { name: 'mixin' } }, created() { console.log('mixin...', this.name); }, mounted() {}, methods: {} }
About usage, vue documentation There is a detailed introduction in , here we only introduce how to use mixin in a vue file.
2. Use mixin in vue files
import '@/mixin'; // 引入mixin文件 export default { mixins: [mixin] }
I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the PHP Chinese website!

命名管道是一种在操作系统中相对比较低级的进程通信方式,它是一种以文件为中介的进程通信方式。在Go语言中,通过os包提供了对命名管道的支持。在本文中,我们将介绍如何在Go中使用命名管道来实现进程间通信。一、命名管道的概念命名管道是一种特殊的文件,可以被多个进程同时访问。在Linux系统中,命名管道是一种特殊的文件类型,它们存在于文件系统的某个位置上,并且可以在

在Go语言中,使用第三方库是非常方便的。许多优秀的第三方库和框架可以帮助我们快速地开发应用程序,同时也减少了我们自己编写代码的工作量。但是如何正确地使用第三方库,确保其稳定性和可靠性,是我们必须了解的一个问题。本文将从以下几个方面介绍如何使用第三方库,并结合具体例子进行讲解。一、第三方库的获取Go语言中获取第三方库有以下两种方式:1.使用goget命令首先

Vue中的mixin是一个非常有用的特性,它可以将一些可重用的代码封装在一个mixin对象中,然后在需要使用这些代码的组件中使用mixin进行引入。这种方法大大提高了代码的可复用性和可维护性,特别是在一些重复的CRUD(增删改查)操作中。本文将介绍如何使用mixin在Vue中实现CRUD操作的技巧。首先,我们需要了解如何创建一个

随着传统的多线程模型在高并发场景下的性能瓶颈,协程成为了PHP编程领域的热门话题。协程是一种轻量级的线程,能够在单线程中实现多任务的并发执行。在PHP的语言生态中,协程得到了广泛的应用,比如Swoole、Workerman等框架就提供了对协程的支持。那么,如何在PHP中使用协程呢?本文将介绍一些基本的使用方法以及常见的注意事项,帮助读者了解协程的运作原理,以

近年来,WebSocket技术已经成为了Web开发中不可或缺的一部分。WebSocket是一种在单个TCP连接上进行全双工通信的协议,它使得客户端和服务器之间的通信更加流畅和高效。如今,很多现代的Web应用程序都使用了WebSocket技术,例如实时聊天、在线游戏以及实时数据可视化等。Go语言作为一个现代的编程语言,自然也提供了很好的支持WebSock

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
