提交前的react-hook-form验证

Question

我有一个表单（抱歉太长了），用户输入姓名、电子邮件、电话、评论非常简单：

    <form
        className={classes.root}
        data-testid="getting-started-form"
        onSubmit={handleSubmit(onSubmit)}
    >
        <div style={{ width: '400px' }}>
            <div style={{ width: '100%'}}>
                <Controller as={<TextField
                    label="Name"
                    id="name"
                    name="name"
                    type="text"
                    value={name}
                    placeholder="Name"
                    onChange={(e: React.FormEvent<EventTarget>) => {
                        let target = e.target as HTMLInputElement;
                        setName(target.value);
                    }}
                    inputProps={{
                        'data-testid': 'name'
                    }}
                />} name="name" rules={{ required: true }} control={control}
                />
                {errors.name && <span>Name is required</span>}
            </div>
            <div style={{ width: '100%' }}>
                <Controller as={<TextField
                    label="Email"
                    id="email"
                    name="email"
                    type="text"
                    value={email}
                    placeholder="Email"
                    style={{ width: '100%' }}
                    onChange={(e: React.FormEvent<EventTarget>) => {
                        let target = e.target as HTMLInputElement;
                        setEmail(target.value);
                    }}
                    inputProps={{
                        'data-testid': 'email'
                    }}
                />} name="email" rules={{ required: true, pattern: /^\w+[\w-\.]*\@\w+((-\w+)|(\w*))\.[a-z]{2,3}$/i }} control={control}
                />
                {errors.email && <span>Email is required</span>}
            </div>
            <div style={{ width: '30%' }}>
                <Controller as={<TextField
                    label="Phone"
                    id="phone"
                    name="phone"
                    type="text"
                    value={phone}
                    placeholder="eg.15556667890"
                    onChange={(e: React.FormEvent<EventTarget>) => {
                        let target = e.target as HTMLInputElement;
                        setPhone(target.value);
                    }}
                    inputProps={{
                        'data-testid': 'phone'
                    }}
                />} name="phone" rules={{ pattern: /\d{11}/ }} control={control}
                />
            </div>
            <div style={{ width: '30%' }}>
                <Controller as={<TextField
                    label="Comments"
                    id="comments"
                    name="comments"
                    type="text"
                    value={comments}
                    placeholder="Comments"
                    rows={6}
                    multiline
                    onChange={(e: React.FormEvent<EventTarget>) => {
                        let target = e.target as HTMLInputElement;
                        setComments(target.value);
                    }}
                    inputProps={{
                        'data-testid': 'comments'
                    }}
                />} name="comments" control={control}
                />
            </div>
        </div>
        <Button
            type="submit"
            aria-label="submit getting-started-form"
            variant="contained"
            color="primary"
            data-testid="getting-started-form-submit-button"
        >
            Submit
        </Button>
    </form>

所有字段在提交时都会经过验证。无论如何，有没有办法让react-hook-forms在提交表单之前进行某种验证？我想要像 Angular 那样的标志来表示脏的、原始的等。

Answer 1

更新！验证器 API： https: //react-hook-form.com/api/。

您可以选择该值onBlur而不是默认onSubmit模式。

您可以在这里关注官方文档：https ://react-hook-form.com/get-started#Registerfields 。

基本上您需要register验证字段。然后react-hook-form将在提交时自动为您验证。

Answer 2

使用模式我们可以这样做：

模式： onChange | 模糊 | 提交 | 触碰 | all = 'onSubmit'（React Native：与控制器兼容）

const { register, trigger, handleSubmit, watch, formState: { errors } } = useForm({
    mode: 'all', // THIS WILL ALLOW ALL-TIME VALIDATION (May have performance impact)
    resolver: yupResolver(ValidationSchema),
  });
