Recently came into contact with learning Vue.js framework combined with Element-ui component development project. Due to the recent need to implement internationalization functions, the following article mainly introduces the relevant information on the use of vue-i18n for the internationalization of vue projects. The article introduces it in detail through sample code. Friends who need it can refer to it.

Preface

The project needs to support multiple languages. We need to extract the static text used in the project and use language packages to manage it. When switching When setting the language, you can automatically switch the text display of the entire project.

I found that there is a corresponding component vue-i18n in the Vue project, and the code of the project was not modified much, so I used this component to modify the code in the project. Not much to say below, let’s take a look at the detailed introduction.

Installation

// script 引入
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-i18n/dist/vue-i18n.js"></script>

// npm 安装
npm install vue-i18n

// yarn 安装
yarn add vue-i18n

Generally, installation is used in a project It is run as a package, and script is introduced less.

Use

Configure i18n in the project

import VueI18n from &#39;vue-i18n&#39;
Vue.use(VueI18n)

const i18n = new VueI18n({
  local: &#39;cn&#39;, // 设置语言 
  messages // 语言包
})

new Vue({
  el: &#39;#app&#39;,
  ...
  i18n
})

// messages 大概的使用格式
{
  cn: {
    name: &#39;名字&#39;
  },
  us: {
    name： &#39;Name&#39;
  }
}

Using i18n

// html 需要使用 {{}} 将 name包装起来
{{$t(&#39;name&#39;)}}

// js
$t(&#39;name&#39;)

There are some other usages, such as:

For Different languages display different formats
If you pass in custom variables to control the display
... Please refer to the official documentation for details .

To switch languages, you can use built-in variables:

// 通过设置 locale 来切换语言
this.$i18n.locale = cn | us

Generation of language pack & Replace the original static text in the project
## This step is the most critical. Extract all Chinese characters that appear and replace them with $t('xxx') to maintain multiple versions. The language file

The language package is handled like this. Add a new directory languages

--languages
  --lib
    -- cn.js // 中文语言包
    -- us.js // 英文语言包
    -- .. // 其他语言，暂未实践
  -- index.js // 导出语言包

cn.js

under the project.

export default {
  common: {
    message: &#39;消息&#39;
  },
  xxx: {
  }
}

us.js

export default {
  common: {
    message: &#39;Messages&#39;
  },
  xxx: {
  }
}

index.js

import cn from &#39;./lib/cn.js&#39;
export default {
  cn,
  us
}

Replacement text

<template>
  ...
  <p>{{$t(&#39;message&#39;)}}</p>
  ...
</template>

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

JS implements the function of moving the left list to the right list

Get using EL expression in JS Methods for context parameter values

jQuery’s method of automatically adding ellipses when the text exceeds 1 line, 2 lines or a specified number of lines

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
