t-comb-form-native 和接受条款的布尔函数

Question

我的注册表单很好用，很好！但我想创建一个布尔字段："terms" 并且我希望在单击它时允许您验证表单。但是如果不点击，你就不能注册。我不知道我该怎么做。

我的想法是提出一个条件"if terms are accepted then => the form is validated and you can go to your account"。在我看来，这是正确的方法，但我不知道该怎么做。也许像我为电子邮件所做的那样创建一个 const 条款，phone 和密码，但是如何写它必须经过验证才能注册？也许在州内有 "accepted false" 之类的东西，但我不知道如何在字段 "terms"...

中传递 "accepted" 选项

感谢您的帮助。

Answer 1

我在状态下添加了"accepted: false" 单击术语时将其传递为真 "this.setState({accepted:true});"

  handleSubmit = async () => {
    const data = this._form.getValue();

    if (
      data &&
      data.email &&
      data.password &&
      data.terms &&
      data.terms === false
    ) {
      return;
    } else if (data && data.email && data.password && data.terms) {
      console.log("SIGNUP::term: ", data.terms);
      this.setState({ accepted: true });
      this.onRegisterPressed(
        data.email,
        data.password,
        data.phone_number,
        data.terms
      );
    } /*
  } else {this.props.navigation.navigate("Authentication")}*/
  };
