傳回匿名函數的回呼函數在 onClick 上給出錯誤

Question

import React from 'react'

export default function Test() {
  const handleClick = () => (label: string) => {
    console.log('label: ' + label)
  }

  return <button onClick={handleClick('red one')}>click me</button>
}

TypeScript 編譯器抱怨我的程式碼，我做錯了什麼？

Type '(label: string) => void' is not assignable to type 'MouseEventHandler<HTMLButtonElement>'.
  Types of parameters 'label' and 'event' are incompatible.
    Type 'MouseEvent<HTMLButtonElement, MouseEvent>' is not assignable to type 'string'.ts(2322)
index.d.ts(1494, 9): The expected type comes from property 'onClick' which is declared here on type 'DetailedHTMLProps<ButtonHTMLAttributes<HTMLButtonElement>, HTMLButtonElement>'

Answer 1

handleClick 函數不需要任何類型的參數，但您向其傳遞一個字串。

應該是：

import React from 'react'

export default function Test() {
  const handleClick = (label: string) => () => {
    console.log('label: ' + label)
  }

  return click me
}

Answer 2

反之亦然

應該是

(label: string) => (e: any) => {

而不是

(e: any) => (label: string) => {

import React from 'react'

export default function Test() {
  const handleClick = (label: string) => (e: any) => {
    console.log('label: ' + label)
  }

  return click me
}
