1.Vue3中集成说明

vue中需要使用highlight.js必须借助highlightjs/vue-plugin 插件来完成

这个插件提供了一个用于Vue.js 3应用程序的组件：highlightjs

注意：vue3中highlightjs/vue-plugin的版本必须为2.x.x, 而1.x.x为vue2的适配版本

关于highlight.js说明请查看 JavaScript之Highlight.js语法高亮显示神器集成说明

2. 安装highlight.js与@highlightjs/vue-plugin

注意：highlight.js与 @highlightjs/vue-plugin必须都安装

shell 复制代码

pnpm install highlight.js
pnpm install @highlightjs/vue-plugin
# or
yarn add highlight.js
yarn add @highlightjs/vue-plugin
# or
npm install highlight.js
npm install @highlightjs/vue-plugin

3. Vue3集成与使用

1. main.ts(或main.js)中导入highlight.js

这里配置为按需引入语言

ts 复制代码

//引入依赖和语言
import 'highlight.js/styles/stackoverflow-light.css'
import hljs from "highlight.js/lib/core";
import hljsVuePlugin from "@highlightjs/vue-plugin";
//import "highlight.js/lib/common"; //单一加载
//按需引入语言
import javascript from "highlight.js/lib/languages/javascript";
import java from "highlight.js/lib/languages/java";
import sql from "highlight.js/lib/languages/sql";
import xml from "highlight.js/lib/languages/xml";
import html from "highlight.js/lib/languages/vbscript-html";
import json from "highlight.js/lib/languages/json";
import yaml from "highlight.js/lib/languages/json";
hljs.registerLanguage("javascript", javascript);
hljs.registerLanguage("java", java);
hljs.registerLanguage("yaml", yaml);
hljs.registerLanguage("json", json);
hljs.registerLanguage("sql", sql);
hljs.registerLanguage("xml", xml);
hljs.registerLanguage("html", html);

const app = createApp(App)
app.use(hljsVuePlugin).mount('#app')

2. 各语言测试代码

CodeHighlightData.ts内容如下

ts 复制代码

export const json: string = `{
    "type": "object",
    "properties": {
        "name": {
            "type": "string"
        },
        "age": {
            "type": "number"
        },
        "address": {
            "type": "object"
        },
        "phoneNumbers": {
            "type": "array",
            "items": {
                "type": "object",
                "properties": {
                    "type": {
                        "type": "string"
                    },
                    "number": {
                        "type": "string"
                    }
                },
                "additionalProperties": false
            }
        }
    },
    "additionalProperties": false
}`

export const js:string = `// Using require
const hljs = require('highlight.js/lib/core');

// Load any languages you need
hljs.registerLanguage('javascript', require('highlight.js/lib/languages/javascript'));
// Using ES6 import syntax
import hljs from 'highlight.js/lib/core';
import javascript from 'highlight.js/lib/languages/javascript';

// Then register the languages you need
hljs.registerLanguage('javascript', javascript);`

export const java:string = `package com.lab.standard.entity;

import com.baomidou.mybatisplus.annotation.TableName;

import java.io.Serializable;
import java.time.LocalDateTime;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Getter;
import lombok.Setter;

/**
 * <p>
 * 用户反馈
 * </p>
 *
 * @author jinshengyuan
 * @since 2023-01-06
 */
@Getter
@Setter
@TableName("std_user_feedback")
@ApiModel(value = "反馈对象", description = "标准-用户反馈")
public class StdUserFeedback implements Serializable {

    private static final long serialVersionUID = 1L;
    private String id;

    @ApiModelProperty(value = "用户ID")
    private String userId;

    @ApiModelProperty(value = "用户名")
    private String userName;

    @ApiModelProperty(value = "用户姓名")
    private String fullName;

    @ApiModelProperty(value = "反馈内容")
    private String remarks;

    @ApiModelProperty(value = "反馈时间")
    private LocalDateTime feedbackTime;
}
`
export const xml:string = `<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.yuan.standard.mapper.StdUserFeedbackMapper">
    <select id="selectImageInfo" resultType="java.util.HashMap" parameterType="string">
        select * from v_sys_upload where bus_id=#{id} and is_del='0'
    </select>
    <update id="deleteImageInfo">
        update v_sys_upload set is_del=1
        <where>
            id in
            <foreach  collection="ids" item="id" index="index"  open="(" close=")" separator=",">
                #{id}
            </foreach>
        </where>
    </update>
</mapper>
`

export const yaml:string = `server:
  port: 8080
  servlet:
    context-path: /upload
spring:
  servlet:
    multipart:
#      设置最大文件
      max-file-size: 20MB
      max-request-size: 1000MB
  application:
    name: yuan-upload-app`

export const sql:string = ` SELECT * FROM USER WHERE ID = ?`

3. 高亮显示vue文件

CodeHighlight.vue内容如下

ts 复制代码

<template>
  语言：
  <el-select v-model="language" @change="languageChange" placeholder="Select" style="width: 240px">
    <el-option
        v-for="item in languageOptions"
        :key="item.value"
        :label="item.label"
        :value="item.value"
        :disabled="item.disabled"
    />
  </el-select>
  <div style="height: 100vh;width: 100vh;line-height: 30px;padding: 5px;">
    <!--
          <highlightjs language="sql" :code="code"></highlightjs>
    -->
    <highlightjs :language="language" :code="code"></highlightjs>
  </div>
</template>

<script setup lang="ts">
import {ref} from "vue";
import {js, json, java, sql, yaml,xml} from './CodeHighlightData.ts'

//默认高亮JS代码
let code = ref(js)
let language = ref('javascript')
//语言选项
const languageOptions = [
  {
    value: 'javascript',
    label: 'js',
  },
  {
    value: 'java',
    label: 'Java'
  },
  {
    value: 'yaml',
    label: 'yaml',
  },
  {
    value: 'sql',
    label: 'sql',
  },
  {
    value: 'json',
    label: 'json',
  },
  {
    value: 'xml',
    label: 'xml',
    disabled: false,
  },
  {
    value: 'html',
    label: 'html',
    disabled: false,
  },
]

/**
 * 语言改变事件处理函数
 * @param language
 */
const languageChange = (language: string) => {
  if ('java' === language) {
    code.value = java
  } else if ('json' === language) {
    code.value = json
  } else if ('yaml' === language) {
    code.value = yaml
  } else if ('sql' === language) {
    code.value = sql
  } else if ('xml' === language) {
    code.value = xml
  } else {
    code.value = js
  }
}

</script>

<style lang="scss" scoped>

</style>

4. Highlight.js-Vue插件详细说明

官网：highlightjs/vue-plugin: Highlight.js Vue Plugin (github.com)

此插件提供了一个组件，用于您的Vue.js 3 个应用程序：highlightjs

js 复制代码

<div id="app">
    <!-- bind to a data property named `code` -->
    <highlightjs autodetect :code="code" />
    <!-- or literal code works as well -->
    <highlightjs language='javascript' code="var x = 5;" />
</div>

注意：有关版本 2 Vue.js支持，请参阅 GitHub 上的 1-stable 分支。版本 1.x.x 与 Vue.js v2 兼容;带有 Vue.js v3 的 2.x.x 版本。

1. 使用预构建的库

js 复制代码

<link rel="stylesheet" href="/path/to/styles/default.css">
<script src="/path/to/highlight.min.js"></script>
<script src="/path/to/highlight-vue.min.js"></script>

然后只需在 Vue 中注册插件：

js 复制代码

const app = createApp(App)
app.use(hljsVuePlugin)

2. 使用 ES6 模块/捆绑

js 复制代码

import 'highlight.js/styles/stackoverflow-light.css'
import hljs from 'highlight.js/lib/core';
import javascript from 'highlight.js/lib/languages/javascript';
import hljsVuePlugin from "@highlightjs/vue-plugin";

hljs.registerLanguage('javascript', javascript);

const app = createApp(App)
app.use(hljsVuePlugin)
app.mount('#app')

注意：插件在内部导入（但没有语言）。由于 ES6 模块的魔力，您可以将Highlight.js导入到任何地方来注册语言或配置库。Highlight.js的任何导入都引用库的同一单一实例，因此在任意位置配置库就是在任意位置配置它。highlight.js/lib/core

您也可以简单地一次加载所有"通用"语言（从 v11 开始）：

js 复制代码

import 'highlight.js/styles/stackoverflow-light.css'
import 'highlight.js/lib/common';
import hljsVuePlugin from "@highlightjs/vue-plugin";

const app = createApp(App)
app.use(hljsVuePlugin)
app.mount('#app')

请注意，导入不会导入对象，因为它在内部注册通用语言，并且现代 Web 捆绑器（如）会优化未使用的导入名称。如果要自定义对象，可以像前面的示例一样导入它。highlight.js/lib/common``hljs``webpack``hljs

3. 在本地使用组件

vue 复制代码

<template>
    <highlightjs
        language="js"
        code="console.log('Hello World');"
    />
</template>

<script>
import 'highlight.js/lib/common';
import hljsVuePlugin from "@highlightjs/vue-plugin";

export default {
    components: {
        highlightjs: hljsVuePlugin.component
    }
}
</script>

4.从源代码构建预构建库

我们使用 rollup 来构建可分发组件。dist

复制代码

npm run build
