Dil*_*eep 2 reactjs yup react-hooks react-hook-form
我是 yup 验证的新手,我正在使用以下选项填充反应选择下拉列表。现在,当我单击一个按钮时,尝试验证是否选择了任何值。但它没有验证。任何帮助深表感谢。
const options = [
{ value: 'active', label: 'Active' },
{ value: 'inactive', label: 'In Active' },
{ value: 'deleted', label: 'Delete' },
];
<Select
defaultValue={options[0]}
isSearchable={false}
className="react-dropdown"
onChange={statusDropdownHandleChange}
classNamePrefix="dropdown"
options={options}
name="status"
{...register("status")}
/>
let schema = yup.object().shape({
status: yup.object().shape({
label: yup.string().required("status is required"),
value: yup.string().required("status is required")
})
});

验证应该有效,但如果您直接使用Selectwith react-hook-form,则在选择值/提交表单时会遇到错误/值未定义,因为Select不会公开输入的引用。因此,您需要Select使用Controller包装来注册组件。
为了验证表单,如果您允许使用isClearable值Select的位置null而不是,则还需要处理另一种情况{label: undefined, value: undefined},因此需要在状态验证结束时添加.nullable()和。.required()
验证
const schema = yup.object().shape({
status: yup
.object()
.shape({
label: yup.string().required("status is required (from label)"),
value: yup.string().required("status is required")
})
.nullable() // for handling null value when clearing options via clicking "x"
.required("status is required (from outter null check)")
});

带有反应选择的形式
<form onSubmit={handleSubmit(onSubmit)}>
<Controller
name="status"
control={control}
render={({ field }) => (
<Select
// defaultValue={options[0]}
{...field}
isClearable
isSearchable={false}
className="react-dropdown"
classNamePrefix="dropdown"
options={options}
/>
)}
/>
<p>{errors.status?.message || errors.status?.label.message}</p>
<input type="submit" />
</form>
