但是，只有一個錯誤顯示，
有多個輸入欄位，我查看了檔案，但不確定我做錯了什么。
原始問題 我目前正在使用 react-hook-form 庫，我在表單上方有所有錯誤，如下所示
{/* errors */}
{errors.length > 0 && (
<div className="mt-6 border-2 border-red-600">
<div className="bg-red-600 text-white py-2 px-4">
<h4>{errors.length} errors occurred:</h4>
</div>
<div className="text-grey-800 py-2 px-4">
<div className="flex flex-col gap-2">
{/* old_password errror */}
<div className="flex flex-col gap-y-6 sm:gap-x-8">
{errors.old_password && (
<small className="text-red-500">
• Old password is required
</small>
)}
</div>
{/* password error */}
<div className="flex flex-col gap-y-6 sm:gap-x-8">
{errors.password && (
<small className="text-red-500">
• Password is required
</small>
)}
</div>
{/* confirm_password errror */}
<div className="flex flex-col gap-y-6 sm:gap-x-8">
{errors.confirm_password && (
<small className="text-red-500">
• Confirm password is required
</small>
)}
</div>
</div>
</div>
</div>
)}
這有效并且錯誤顯示，不確定是否有辦法映射錯誤以使代碼更清晰，因此任何想法都會很棒。
但是，如何隱藏錯誤塊，我有{errors.length > 0 && (，但這似乎不起作用。
這是一個視覺效果
任何幫助都會很棒。
uj5u.com熱心網友回復：
因為errors是一個物件.length對它不起作用。但是您可以使用Object.keys(errors).length > 0動態顯示錯誤塊。類似的東西：
{Object.keys(errors).length > 0 && (
<div className="mt-6 border-2 border-red-600">
<div className="bg-red-600 text-white py-2 px-4">
<h6>Following errors have occurred</h6>
</div>
<div className="text-grey-800 py-2 px-4">
<div className="flex flex-col gap-2">
{/* Here you put one ErrorMessage for each input*/}
<ErrorMessage
errors={errors}
name="old_password"
render={({ message }) => (
<div className="flex flex-col gap-y-6 sm:gap-x-8" key={type}>
<small className="text-red-500">{message}</small>
</div>
)}
/>
</div>
</div>
</div>
你的輸入必須是這樣的：
<input
{...register("old_password", { required: "Old password is required" })}
id="old_password"
type="password"
className="your classes"
onChange={(event) => setOldPassword(event.target.value)}
/>
