javascript - react Material 重置表格值

Question

我正在使用带钩子(Hook)的 react Material ，我想对 Material 形式进行重置。

我一直在尝试设置状态，但没有反射(reflect)任何变化

<form className="create-account-form" autoComplete="off" onSubmit={onSubmit}>
  <FormControl
    error={!!errorText.first_name}
    variant="outlined"
    size="small"
    fullWidth
  >
    <InputLabel>First Name</InputLabel>
    <OutlinedInput
      name="first_name"
      className="create-account-input"
      labelWidth={90}
      disabled={loading}
      onChange={event => handleChange("first_name", event)}
    />
  </FormControl>
  <Button
    type="submit"
    className="submit-button"
    color="primary"
    variant="contained"
  >
    Submit
  </Button>
</form>;
//my state varibles

const [signUpData, setSignUpData] = useState({
  first_name: ""
});
const handleChange = (field, event) => {
  if (event) {
    setSignUpData({
      ...signUpData,
      [field]: event.target ? event.target.value : event
    });
  }
};

提交时我想清除输入字段中的数据。

const onSubmit = e => {
  e.preventDefault();
   setSignUpData((prev) => (prev.first_name = "",));

  // clearfunction()
};

Answer 1

加载初始状态

const init = {first_name: ''};
const [signUpData, setSignUpData] = useState(init)

const onSubmit = (e) => {
  e.preventDefault();
  // do submit logic
  setSignUpData(init)
}
