Topic: MDB DatePicker useState React
Expected behavior
I want to use the value and onChange prop with MDBDatepicker with React's useState variables and custom change handler. How can I accomplish this?
Actual behavior I get an error in the dev tools: "Uncaught TypeError: Cannot read properties of undefined (reading 'value')"
Resources (screenshots, code snippets etc.)
Form snippet
<label htmlFor='investment-date'>Investment Date</label>
<MDBDatepicker
icon='fas fa-calendar'
format='m/d/yyyy'
value={userInput.enteredInvDate}
onChange={invDateChangeHandler}
/>
useState snippet
const [userInput, setUserInput] = useState({
...
enteredInvDate: company.investmentDate, // a string in format 'm/d/yyyy'
...
})
Change Handler snippet
const invDateChangeHandler = (event) => {
setUserInput((prevState) => ({
...prevState,
enteredInvDate: event.target.value
}))
}
Your onChange function should look this way:
onChange={(date) => {
setUserInput((prevState) => ({
...prevState,
enteredInvDate: date,
}));
}}
Datepicker is not a normal input, so it does not return an event on change.

I am using MDB React UI Kit v5.0.0 and still cannot use the value and onChange properties.
const investmentDateHandler = (date) => {
setUserInput((prevState) => ({
...prevState,
// enteredInvestmentDate: event.target.value,
enteredInvestmentDate: date,
}));
};
<DatePicker format="m/d/yyyy" value={userInput.enteredInvestmentDate} onChange={(date) => investmentDateHandler(date)} />
