无法在最终表单数组上设置initialValue

const [formArray, setFormArray] = useState([{ name: '', age: '' }]);

// 设置初始值
useEffect(() => {
  setFormArray([{ name: 'John', age: '25' }]);
}, []);

// 在表单中使用formArray

{formArray.map((item, index) => (
  <div key={index}>
    <input type="text" name={`name[${index}]`} value={item.name} />
    <input type="text" name={`age[${index}]`} value={item.age} />
  </div>
))}

import { Formik, Field, FieldArray } from 'formik';

const initialValues = {
  formArray: [{ name: 'John', age: '25' }]
};

<Formik initialValues={initialValues} onSubmit={handleSubmit}>
  {({ values }) => (
    <FieldArray name="formArray">
      {({ push, remove }) => (
        <div>
          {values.formArray.map((item, index) => (
            <div key={index}>
              <Field name={`formArray[${index}].name`} />
              <Field name={`formArray[${index}].age`} />
            </div>
          ))}
        </div>
      )}
    </FieldArray>
  )}
</Formik>
