vue点击项目唯一id生成器nanoid的使用方式

npm i nanoid 
// 或者 yarn add nanoid

import { nanoid } from 'nanoid' 
let id = nanoid()
 
//也可以指定生成字符串的长度
//let id = nanoid(5)

npm i nanoid

yarn add nanoid

import {nanoid} from 'nanoid'

import React, { Component } from 'react'
import {nanoid} from 'nanoid'
import "./index.CSS"
export default class Header extends Component {
    handleKeyUp = (event) => {
        const {keyCode, target} = event;
        // 判断是否是回车
        if (keyCode !== 13) return
        if (target.value.trim() === '') {
            alert("输入不能为空")
            return
        }
        const todoObj = {id:nanoid(),name:target.value,done:false}
        this.props.addTodo(todoObj)
        target.value = ''
    }
    render() {
        return (
            <div className="todo-header">
                <input onKeyUp={this.handleKeyUp} type="text" placeholder="请输入你的任务名称，按回车键确认"/>
            </div>
        )
    }
}
