我打電話跟裁判子功能,但孩子的功能有降低作用,故一點兒也不工作:使用REF與mapStateToProps不起作用reactjs

我的父母:

search(data) { 
    this.SearchProduct.search(data); 
} 
... 
<SearchProduct ref={instance => { this.SearchProduct = instance; }} /> 

我的孩子:

class SearchProduct extends React.Component { 
... 

    search(data) { 
     console.log(data) 
    } 
... 
} 

const mapStateToProps = (state, ownProps) => ({ 
    basket: state.basket, 
}); 


const mapDispatchToProps = (dispatch, ownProps) => ({ 

    setBasket: (basket) => { 
     dispatch({ type: 'SET_BASKET', basket }); 
    } 
}); 

module.exports = connect(
    mapStateToProps, 
    mapDispatchToProps, 
    null, 
    { withRef: true } 
)(SearchProduct); 

當我火了:

component.js:25 Uncaught TypeError: this.SearchProduct.search is not a function 

任何人有一個想法?

感謝的很多

你需要得到包裹例如像這樣

search(data) { 
    this.SearchProduct.getWrappedInstance().search(data); 
}
