我正在尝试构建一个注册表单,我已经构建了登录表单并且它工作得很好,但是注册表单很差。
首先,我使用这些
react-dev
工具检查正在发生的事情,我意识到input
来自注册表单的每个值都恰好位于array
.我回到登录表单进行检查,发现
input
字段的值格式正确(strings
)。但是注册表单中每个特定input
字段的值都在. 我可能做错了什么?array
我试图在注册表单中复制我在登录表单中所做的操作,但它仍然以. 还有,应该保存在自己的单独文件中吗?
array
hooks
这是我从注册表react-dev
工具中看到的。
这是我所做的代码片段。
const Signup = (props) => {
const authContext = useContext(AuthContext);
const { register, clearErrors, isAuthenticated, error } = authContext;
const [loadBtn, updateLoadBtn] = useState(false);
const [user, setUser] = useState({
firstName: "",
lastName: "",
email: "",
password: "",
username: "",
phoneNumber: "",
});
useEffect(() => {
if (isAuthenticated) {
successMessage();
props.history.push("/dashboard");
}
if (error) {
missingValue(error);
updateLoadBtn(false);
clearErrors();
}
//eslint-disable-next-line
}, [isAuthenticated, error, props.history]);
const { firstName, lastName, email, password, username, phoneNumber } = user;
const onChange = (e) =>
setUser({ ...user, [e.target.name]: [e.target.value] });
const onSubmit = (e) => {
e.preventDefault();
updateLoadBtn(true);
if (
!firstName ||
!lastName ||
!email ||
!password ||
!username ||
!phoneNumber
) {
missingValue("Please enter all fields");
updateLoadBtn(false);
clearErrors();
} else {
register({
firstName,
lastName,
email,
password,
username,
phoneNumber,
});
}
};
return (
<Fragment>
<ToastContainer />
<RegContainer className="container-fluid py-4">
<RegInfo />
<RegColumn
onChange={onChange}
onSubmit={onSubmit}
firstName={firstName}
lastName={lastName}
email={email}
password={password}
phoneNumber={phoneNumber}
loadBtn={loadBtn}
/>
</RegContainer>
</Fragment>
);
}
那是负责处理注册的文件。
这是自定义组件
const RegColumn = ({
firstName,
onSubmit,
onChange,
lastName,
username,
password,
phoneNumber,
email,
loadBtn,
}) => {
const bodyStyle = document.querySelector("body").style;
bodyStyle.backgroundImage = "linear-gradient(to bottom, #F6F6F2, #C2EDCE)";
bodyStyle.backgroundRepeat = "no-repeat";
bodyStyle.overflow = "hidden";
bodyStyle.height = "100%";
bodyStyle.fontFamily = "Rubik, sans-serif";
return (
<Fragment>
<div id="reg-column">
<h3 style={{ color: "#388087" }}>REGISTRATION</h3>
<Form divid="form-row1-label" onSubmit={onSubmit}>
<LabelContainer id="form-row1-label">
<LabelContainer id="firstNameLabel">
<LabelInfo labelfor="firstName" labeltitle="First Name" />
</LabelContainer>
<LabelContainer id="lastNameLabel">
<LabelInfo labelfor="lastName" labeltitle="Last Name" />
</LabelContainer>
</LabelContainer>
<InputContainer id="form-row1-input">
<InputContainer id="firstNameInput">
<Input
type="text"
name="firstName"
value={firstName}
id="firstName"
onChange={onChange}
/>
</InputContainer>
<InputContainer id="lastNameInput">
<Input
type="text"
onChange={onChange}
name="lastName"
value={lastName}
id="lastName"
/>
</InputContainer>
// ...
谢谢你。
