如何传递带有参数的 function 与 typescript 反应

Question

I want to pass a handleClick to the son so I don't have to do it twice. The code is the following:

Mother:

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}/>
        </>
    )
}

Son:

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 : ''}/>
        //...
        </>
    )
}

Basically this sets the background color in case an option is selected or not. MyComponent is a component that takes that props (and/or others) and sets its own content.

This throws the type error _onClick is not a function . I believe I didn't do it properly.. What did I miss, in your opinion?

Answer 1

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

Replace with

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

Answer 2

Son Will be called with all props that you've to Destructur it or directly read from props

(selectedOption, onClick, customSectionStyle) should be ({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

are you sure about returning two adjacent MyComponent over there? And I think that you miss the curly braces when getting the props in the son component definition =

({ selectedOption, onClick, customSectionStyle })
