我想有条件地在我的表单中显示错误。
formik 的工作方式是,如果您更改一个字段,所有验证都会运行,并且即使您只更改了一个字段,也会返回所有错误。
我只想在字段被触摸并且我希望字段被触摸 onChange 时才显示错误。对字段的第一次更改应该使它被触及。
目前 formik 在提交时正在触及字段。我怎么能在改变时触摸它?
这是我目前的形式:
const optionsForSelect = (collection) => {
return collection.map(item => ({
value: item.id,
label: item.name
}))
}
const validationSchema = yup.object().shape({
length: yup
.number()
.min(1, 'Length should be a positive non-zero integer')
.required(),
frame_rate: yup
.string()
.required()
})
class SpecificationsForm extends React.PureComponent {
render() {
const {
values,
handleChange,
handleInputChange,
handleSelectChange,
handleBlur,
errors,
touched
} = this.props;
const debouncedHandleChange = debounce(handleChange, 200)
console.log(errors)
console.log('TOUCHED')
console.log(touched)
return (
