我正在尝试寻找一种更好的方式来对表单进行onChange验证,但是由于存在多个转贴,因此实在太麻烦了。
这是我的useEffect代码:
useEffect(() => {
if (passwordValues.password) {
setValidPassword({ confirmPassword: validateConfirmPassword(correctPassword), password: validatePassword(correctPassword) })
}
if(formData.name){
setValidFormData(validFormData => ({...validFormData, name: validateData(correctFormData, "name")}))
}
if(formData.lastName){
setValidFormData(validFormData => ({...validFormData, lastName: validateData(correctFormData, "lastName")}))
}
if(formData.email){
setValidFormData(validFormData => ({...validFormData, email: validateData(correctFormData, "email")}))
}
if(formData.phone){
setValidFormData(validFormData => ({...validFormData, phone: validateData(correctFormData, "phone")}))
}
}, [passwordValues, correctPassword, correctFormData, formData])
我知道我也许可以在几行中做到这一点,但是那是在做那么多的退赛吗?
每次输入更改时,我的formData,passwordValues,correctPassword和correctFormData都会更改。
-编辑-
我删除了数组中的大多数依赖项,而我仍然使用[formData],虽然提高了速度,但仍然有些滞后。

我在这里写它,因为它会有点冗长,不适合发表评论。
这些情况在任何应用程序中都很常见,在这种情况下,您必须对值的更改做出反应并解决此问题,我刚刚创建了一个特殊的钩子use-effect-x(正在编写测试)
此自定义钩子将告诉您更改的项目集,在这里可能非常有用。下面是代码,我能够根据您的输入编写代码。您可以在各处使用useEffectX代替useEffect。这样,不需要的setValidFormData将不会运行。试试看,让我知道。
import { useEffectX } from "use-effect-x";
useEffectX(
({
changedItem: [
changeObjConfirmPassword,
changeObjPassword,
changeObjName,
changeObjLastname,
changeObjEmail,
changeObjPhone,
],
}) => {
if (changeObjConfirmPassword.changed) {
setValidPassword({
confirmPassword: validateConfirmPassword(confirmPassword),
});
}
if (changeObjPassword.changed) {
setValidPassword({
password: validatePassword(correctPassword),
});
}
if (changeObjName.changed) {
setValidFormData((validFormData) => ({
...validFormData,
name: validateData(correctFormData, "name"),
}));
}
if (changeObjLastname.changed) {
setValidFormData((validFormData) => ({
...validFormData,
lastName: validateData(correctFormData, "lastName"),
}));
}
if (changeObjEmail.changedd) {
setValidFormData((validFormData) => ({
...validFormData,
email: validateData(correctFormData, "email"),
}));
}
if (changeObjPhone.changed) {
setValidFormData((validFormData) => ({
...validFormData,
phone: validateData(correctFormData, "phone"),
}));
}
},
[confirmPassword, password, name, lastName, email, phone]
);
谢谢,让我知道,如果这不是您所期望的建议,我会提出。
