如何傳遞帶有參數的 function 與 typescript 反應

Question

我想將 handleClick 傳遞給兒子，所以我不必做兩次。 代碼如下：

母親：

const Mother = () => {
    const [selectedOption, setSelectedOption] = useState<'rooms' | 'questions' | 'notifications'>('rooms')

    const customSectionStyle = 'bg-primary-500 text-white hover:bg-primary-600'

    //handle click
    const handleClick = (href, section) => {
      setSelectedOption(section);
      router.push(href)
    }
    return(
        <>
            <Son onClick={() => handleClick} selectedOption={selectedOption} customSectionStyle={customSectionStyle}/>
        </>
    )
}

兒子：

const Son: React.FC<{ selectedOption?: string | '', onClick?: (href: string, section: string) => void | void, customSectionStyle?: string | '' }> = (selectedOption, onClick, customSectionStyle) => {
    return(
        <>
            <MyComponent onClick={() => {onClick('/','home')}} customStyle={selectedOption === 'rooms' ? customSectionStyle : ''}/>
            <MyComponent onClick={() => {onClick('/','settings')}} customStyle={selectedOption === 'settings' ? customSectionStyle : ''}/>
        //...
        </>
    )
}

基本上，這會設置背景顏色，以防選擇或不選擇選項。 MyComponent是一個組件，它采用該道具（和/或其他）並設置自己的內容。

這會引發類型錯誤_onClick is not a function 。 我相信我沒有正確地做到這一點。在你看來，我錯過了什么？

Answer 1

const Son: React.FC<{ selectedOption?: string | '', onClick?: (href: string, section: string) => void | void, customSectionStyle?: string | '' }> = (selectedOption, onClick, customSectionStyle)

用。。。來代替

const Son: React.FC<{ selectedOption?: string, onClick?: (href: string, section: string) => void, customSectionStyle?: string }> = ({ selectedOption, onClick, customSectionStyle })

Answer 2

兒子將被調用所有你必須破壞它的道具或直接從道具中讀取

(selectedOption, onClick, customSectionStyle) 應該是 ({selectedOption, onClick, customSectionStyle})

 const Son: React.FC<{ selectedOption?: string | '', onClick?: (href: string, section: string) => void | void, customSectionStyle?: string | '' }> = ({selectedOption, onClick, customSectionStyle}) => { return( <MyComponent onClick={() => {onClick('/','home')}} customStyle={selectedOption === 'rooms'? customSectionStyle: ''}/> <MyComponent onClick={() => {onClick('/','settings')}} customStyle={selectedOption === 'settings'? customSectionStyle: ''}/> //... ) }

Answer 3

你確定要在那里返回兩個相鄰的 MyComponent 嗎？ 而且我認為您在獲取子組件定義中的道具時會錯過花括號=

({ selectedOption, onClick, customSectionStyle })
