如何从 object 内的数组中的对象输入 questionText

Question

I have tried to enter questionText by inputFields.questions.questionText, but it is not working

 const [inputFields, setInputFields] = useState([ { sectionName: "", sectionDesc: "", questions: [{ questionType: "", questionText: "" }], }, ]); <input value={inputFields.questions.questionText} />

Answer 1

1) questions and inputFields are arrays not an object so you should use index to access its value as:

value={inputFields[0].questions[0].questionText}

2) If you want to change input value on input of value then you have to use onChange here as:

function onChangeInput(e) {
    setInputFields((currValue) => {
        const clone = [...currValue];
        clone[0].questions[0].questionText = e.target.value;
        return clone;
    });
}

Answer 2

This is an array. This is not an object. Hence, for accessing the value you should use the index of the array:

inputFields[index].questions[index].questionText
