我正在尝试反应钩子形式。无论如何在提交时不重置表单？每次我点击提交表单都会重置。

从“反应”导入反应；从“react-hook-form”导入 { useForm }；

import {
  Row,
  Col,
  Card,
  CardHeader,
  CardBody,
  Form,
  FormGroup,
  Label,
  Input,
  Button
} from "reactstrap";

const Insights = props => {
  const { register, handleSubmit, watch } = useForm();

  const GetSearchForm = () => {
    const timePickerStyle = { width: 96, important: "true" };

    const onSearch = data => {
      console.log(data);
    };

    return (
      <Form onSubmit={handleSubmit(onSearch)}>
        <Row>
          <Col>
            <FormGroup>
              <Label for="exampleEmail">Account Id</Label>
              <Input
                type="number"
                name="account"
                id="account"
                placeholder="AccountId"
                innerRef={register}
              />
            </FormGroup>
          </Col>
          <Col>
            <FormGroup>
              <Label for="examplePassword">Email</Label>
              <Input
                type="email"
                name="email"
                id="email"
                placeholder="Email"
                innerRef={register}
              />
            </FormGroup>
          </Col>

          <Col>
            <FormGroup>

因为GetSearchForm是它自己的组件，所以每次Insights重新渲染时都会创建它。

您使用 innerRef 调用该register函数，但是由于已Input更改，并且它不是同一个组件（新创建的），因此它是新注册的，这会重置状态。

您可以将 移至useForm并GetSearchForm在提交时将数据传回或将整个表单内联到Insights.
