잡히지 않은 TypeError : _this.props.onToggle은 함수가 아닙니다.

Question

제 코드는 제 3 자 API에서 데이터를 가져 와서 배열에 넣습니다. 그런 다음 <Result /> 구성 요소 목록으로 표시됩니다. ID가 항목을 클릭 할 수 좋아하고 그것이 <ChosenList />

_this.props.onToggle is not a function

에 추가 한 ... 내가지고있어 오류입니다.

수있는 사람이 오류를 알아내는 데 도움이 있나요?

Answer 1

onToggle 용 처리기를 ChosenList에 전달하지만 ChosenList는 호출하려고하는 Result 하위 항목으로 ChosenList를 전달하지 않습니다. 당신은

var ChosenList = React.createClass({ 
    handleAddChosen: function(){ 

    }, 
    render: function() { 
    var {chosenList, onToggle} = this.props; 
    var renderChosen =() => { 
     return chosenList.map((chosen) => { 
     return (
      <Result key={chosen.id} {...chosen} onToggle={onToggle} /> 
     ); 
     }); 
    }; 
    return (
     <div> 
     {renderchosen()} 
     </div> 
    ); 
    } 
});
