react 代码块输出,代码高亮显示,带行号,能复制
以modal组件为例
import React, { useState, useEffect } from 'react'; import { Modal, Button, message } from 'antd'; import Highlight from 'react-highlight'; import "highlight.js/styles/mono-blue.css"; import { CopyToClipboard } from 'react-copy-to-clipboard'; import "./infoModal.less"; import hljs from 'highlight.js'; export default function infoModal(props: any) { const { visible, handleCancel, handleOk, modalType } = props; const [title, setIitle] = useState(''); const [num, setNum] = useState(0); const [data, setData] = useState({ "a": title, "a2": "1", "a3": "1", "a4": "1", "a5": "1", "a6": "1", "a7": "1", "a8": "1", "a9": "1", }); useEffect(() => { if (modalType === "in") { setIitle("入参信息") } else { setIitle("出参信息") }; }, [modalType]); //显示行号 useEffect(() => { if (visible) { hljs.initHighlightingOnLoad(); document.querySelectorAll('pre code').forEach((block) => { block.innerHTML = "<ul id='ulcode'><li>" + block.innerHTML.replace(/\n/g, "\n</li><li>") + " </li></ul>"; }); } }, [visible]) const handleCopy = () => { message.success('复制成功!') }; return <div> <Modal title={title} visible={visible} onCancel={handleCancel} onOk={handleOk} footer={[ <CopyToClipboard text={JSON.stringify(data, null, 2)} onCopy={handleCopy}> <Button>复制</Button> </CopyToClipboard>, <Button key="submit" type="primary" onClick={handleCancel}>确定</Button> ]} > <Highlight className="javascript mycode" > {JSON.stringify(data, null, 2)} </Highlight> </Modal> </div>; }
infoModal.less样式
.hljs ul { list-style: decimal; margin: 0 0 0 40px!important; padding: 0 } .hljs li { list-style: decimal-leading-zero; border-left: 1px solid #333!important; padding: 2px 5px!important; margin: 0!important; line-height: 14px; width: 100%; box-sizing: border-box } .hljs li:nth-of-type(even) { background-color: rgba(255,255,255,.015); color: inherit } .javascript{ max-height:400px; }
效果图:
- 代码块显示:react-highlight插件
- 代码块复制:react-copy-to-clipboard插件
- 代码块显示行号:highlight.js插件+js代码(上文中已注释)+less样式(上文中已添加)
react 代码块插件
代码块插件
vscode扩展搜索 ES7 React/Redux/GraphQL/React-Native snippetsd或者React-Native/React/Redux snippets for es6/es7 并安装(如果安装后者 直接cccs可以一键生成模板块 安装前者 步骤如下)
以上为个人经验,希望能给大家一个参考,也希望大家多多支持我们。
