我似乎找不到我正在使用 Gatsby 的问题，我创建了一个 Ref 来处理输入的表单验证，由于某种原因，非常基本的东西出错了
这是html：
<form onSubmit={(event) => handleSubmit(event, email)}>
<label htmlFor="email">Our newsletter</label>
<input
value={email || ''}
name="email"
placeholder="La tua e-mail"
type="text"
spellCheck="false"
className="input"
onChange={() => setEmail(myRef.current.value)}
ref={myRef}
/>
<button className="button" onClick={checkInput} type="submit">
Iscriviti
</button>
{message && (
<>
<br />
<small>{message.substring(0, 45)}</small>
</>
)}
</form>
这些是功能
const [message, setMessage] = useState();
const [email, setEmail] = useState('');
let myRef = useRef();
function handleSubmit(event, email) {
event.preventDefault();
addToMailchimp(email) // listFields are optional if you are only capturing the email address.
.then((data) => {
// I recommend setting data to React state
// but you can do whatever you want (including ignoring this `then()` altogether)
setMessage(data.msg);
})
.catch(() => {
// unnecessary because Mailchimp only ever
// returns a 200 status code
// see below for how to handle errors
});
}
const checkInput = () => {
console.log(myRef);
if (myRef.current.value === '') {
setErrorFor();
} else if (!isEmail(myRef.current.value)) {
setErrorFor();
} else {
setSuccessFor();
}
};
function setErrorFor() {
const formControl = myRef.current;
formControl.className = 'error shaka';
}
function setSuccessFor() {
const formControl = myRef.current;
formControl.className = 'success';
}
function isEmail(email) {
return /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/.test(
email
);
}
这是CSS
