在React中单击模态关闭按钮后如何重置模态输入状态?

Question

关闭模态输入手机号码后，再次点击Form Submit按钮，输入框显示之前输入的号码。我相信模型本身捕获了以前的状态，我想在我们打开模态时清除它。

在Modal中输入OTP输入后，如果我们点击Edit mobile number，当我们再次输入手机号码时，那么之前输入的OTP也会显示出来。我想在输入新的手机号后清除。

我已经尝试过将onclick事件的状态设置为(")，但它没有帮助。

我真的需要一些帮助。

代码:

export default function Form() {
// form default hooks
const {register,handleSubmit, formState: { errors, isValid },} = useForm({mode: "onChange",criteriaMode: "all",});
const {register: register2,handleSubmit: handleSubmit2,formState: { errors: errors2 },} = useForm({mode: "onChange",});
const [verifyOTPFlag, setVerifyOTPFlag] = useState(true);
//modal hooks
const [mobileNumberInput, setMobileNumberInput] = useState(true);
const [postVerificationMessage, setPostVerificationMessage] = useState();
const [otpVerificationResult, setOtpVerificationResult] = useState(false);
const [show, setShow] = useState(false);
const [otpInput, setShowOtpInput] = useState(false);
const [number, setNumber] = useState("");
const [OTP, setOTP] = useState("");
const [counter, setCounter] = useState(59);
// post office and aadhar hooks
const [districtName, setDistrictName] = React.useState("");
const [stateName, setStateName] = React.useState("");
//-------------------------modal functionalities start-------------------------
const handleClose = () => {
setShow(false);
setShowOtpInput(false);};
const handleShow = () => {
setShow(true);};
const showOtpInput = () => {
getOTP(number);
setOTP("");
setShowOtpInput(true);
setMobileNumberInput(false);
setOtpVerificationResult(false);
};
const onSubmit = (data) => {
data["district"] = districtName;
data["state"] = stateName;
setMobileNumberInput(true);
setPostVerificationMessage("");
setNumber("");
if (verifyOTPFlag) {
if (isValid) {
setShow(true);
} else {}
} 
};
const onSubmit2 = () => {
verifyOTP(OTP)
.then((resp) => {
alert("OTP verification Successful");
setPostVerificationMessage(<p className="text-danger">OTP verification Successful</p>);
setVerifyOTPFlag(false);
setOtpVerificationResult(true);
setShowOtpInput(false);
})
.catch((error) => {
setPostVerificationMessage(<p className="text-danger"> OTP verification Failed. Kindly enter the correct OTP</p> )      
setOtpVerificationResult(true);
});};
const onClickEditMobileNo = () => {
setShowOtpInput(!otpInput);
setOtpVerificationResult("");
setOTP("");
setMobileNumberInput(true);
};
return (

最简单的方法就是在onSubmit函数中添加e.target.reset()。

const onSubmit = (data, e) => {
data["district"] = districtName;
data["state"] = stateName;
setMobileNumberInput(true);
setPostVerificationMessage("");
setNumber("");
e.target.reset();
if (verifyOTPFlag) {
if (isValid) {
setShow(true);
} else {}
}
};

也保持这样的setNumber("")。我想这能解决问题。
