Stack Overflow Asked by Will Black on December 23, 2021
I got form (use formik + andt). Can’t find how to add function when Input changes.
for example my mail field:
<Form.Item
help={fieldHelp()}
validateStatus={fieldValidateStatus('email')}
label="E-mail"
name="email"
>
<Input
value={values.email}
onChange={handleChange} // how to add function here?
onBlur={handleBlur}
/>
</Form.Item>
is it possible to add one more function to onChange={handleChange}?
somethiing like this: onChange={handleChange, myfunction()} or another way?
yes you can call multiple functions this way
onChange={(e) => {
handleChange(e);
myfunction()
}}

You 'll need to create a custom component for TextInput and manually pass error to it...
<MyAppTextInput
...
onChangeText={handleChange('latin')}
onBlur={handleBlur('latin')}
error={touched.latin && errors.latin}
/>
const onYourFieldChange = fieldName => {
handleChange(fieldName);
YourCustomFn();
};
