'Formik onChange is not working for dropdown using react-select
Below is the code where I am trying to select value from dropdown. handleChange is not working, when I select the value from dropdown it's not getting updated with selected value from dropdown. It's getting vanished(blank).
Dropdown values are getting populated when I select it's not catching the new selected value.
Can someone help me on this like what I am missing here?
export const FormikSelectField = ({ label, ...props }) => {
const [field, meta] = useField(props);
const [isFocused, setOnFocus] = useState(false);
const handleChange = (value) => {
// this is going to call setFieldValue and manually update values.topcis
console.log('Value in handlechange..', value ,'and', props.name);
props.onChange(props.name, value.value);
};
const handleFocus = () => {
setOnFocus(true);
};
const handleBlur = (e) => {
// this is going to call setFieldTouched and manually update touched.topcis
setOnFocus(false);
props.onBlur(props.name, true);
field.onBlur(e);
};
return (
<>
<label htmlFor={props.labelName}>{props.labelName} </label>
<Select
id={props.labelName}
options={props.options}
isMulti={false}
onChange={handleChange}
onBlur={(e) => handleBlur(e)}
placeholder='Select an option'
onFocus={handleFocus}
value={props.value}
/>
{meta.touched && meta.error && !isFocused ? (
<div className="error">{meta.error}</div>
) : null}
</>
);
};
formikInitialValues = () => {
return {
Name: [{
title: '',
value: '',
}]
};
};
YupValidationSchema = () => {
return Yup.object({
Name: Yup.array()
.of(
Yup.object().shape({
title: Yup.string().required(),
value: Yup.string().required(),
})
)
.required("Please select an option")
.nullable()
});
};
<FormikSelectField
value={this.state.selectNameOption}
onChange={this.handleNameChange}
onBlur={this.handleNameChangeBlur}
error={formik.errors.Name}
options={this.state.NameOptions}
touched={formik.touched.Name}
name="Name"
labelName="Name"
/>

You should avoid mixing the state when using Formik. Formik will take care of the state for you.
import { Formik, Form, useField, ErrorMessage } from "formik";
import * as Yup from "yup";
import Select from "react-select";
const iceCreamOptions = [
{ value: "chocolate", label: "Chocolate" },
{ value: "strawberry", label: "Strawberry" },
{ value: "vanilla", label: "Vanilla" }
];
const FormSelect = ({ name, options }) => {
const [field, meta, helpers] = useField(name);
return (
<>
<Select
name={name}
value={field.value}
onChange={(value) => helpers.setValue(value)}
options={options}
onBlur={() => helpers.setTouched(true)}
/>
<ErrorMessage name={name} />
</>
);
};
const initialValues = {
icecream: null
};
const validationSchema = Yup.object().shape({
icecream: Yup.object()
.shape({
value: Yup.string(),
label: Yup.string()
})
.required("Please select a value")
.nullable()
});
export default function App() {
return (
<Formik
initialValues={initialValues}
onSubmit={(values) => console.log(values)}
validationSchema={validationSchema}
>
{(props) => {
return (
<Form>
<pre>{JSON.stringify(props, undefined, 2)}</pre>
<FormSelect name="icecream" options={iceCreamOptions} />
</Form>
);
}}
</Formik>
);
}

Write this code
onChange={(e:React.ChangeEvent<HTMLInputElement>)=> setFieldValue("title",e.target.value)}
or
onChange={(e)=> setFieldValue("title",e.target.value)}
