问题 How do you create a YUP schema with dynamic dot notation field names? The below schema is not valid. How would I iterate through Costs.0.item, Costs.1.item, Costs.2.item AND Costs.0.amount, Costs.1.amount, Costs.2.amount dynamically? Any help is appreciated! const IpSchema = Yup.object().shape({ Project_Title: Yup.string() .min(2, 'Too Short!') .max(255, 'Too Long!') .required('Required'), Costs.0.item: Yup.string() .min(2, 'Too Short!') .max(255, 'Too Long!') .required('Required'), Costs.1

问题 I have a form that creates an event using Formik library. I need to check to see if the start date overlaps the end date and vice-versa. I have two date pickers that choose the date and time. How can I use Yup to validate this and show an error message if they do overlap? Thanks for the help in advance const validationSchema = Yup.object().shape({ eventName: Yup.string() .min(1, "Must have a character") .max(10, "Must be shorter than 255") .required("Must enter an event name"), email: Yup

问题 Is there a way to pass formik form values from a child component to a parent component and handle form submission in parent component only. I have a use case where I'm building a form for restaurant. The form will have many many fields. So I grouped them and created seperate smaller formik forms component. All the child components' validation schema (yup) are written there inside the child component. Or if there is any another method to accomplish this task, please let me know. class

问题 I am trying to use Formik + Yup to validate my form, but currently if I touch one field, and then try and submit, a field that has a minimum length will validate, and not allow me to submit. Following my code sandbox (https://codesandbox.io/s/focused-bardeen-5fiuz), I want the user to be able to submit the form if they just change the firstName field, but without entering anything for the country field. I tried both the .notRequired() and .nullable(true) params, but did not work. Any idea how

问题 I want execute a custom function when the field become valid? Something like this.. <Field name="postal-code" onValid={...} /> The reason is that I want make fetch (GET) to get address from API once the user type an valid Postal code 回答1: You can define the custom function inside the component class or outside the component. // outside the component (best suited for functional component) const onValidFn = () => { // perform action } // inside the component (best suited for stateful component)
