Answer 1

Just use this:

handleChange = date => {
  const valueOfInput = date.format();
  ///...
};

Because this datepicker returns a moment.js object!

For more information, look into the moment.js docs here.

Answer 2

I have same problem, and I solved it by using the below solution. Please try it:

<p>{this.state.date.toLocaleDateString()}</p>

Answer 3

The new version of react-datepicker library stopped using a moment.js object, so here is my solution if you want to get a formatted string representation of the date.

First import import format from "date-fns/format"; Then

    <DatePicker 
       onChange={(value)=>this.handleChange(format(value, "yyyy/MM/dd", { 
       awareOfUnicodeTokens: true }))}
       dateFormat="yyyy/MM/dd"
       selected={this.state.inputValue} otherProps={here} />
    ...

You can use the getTime() helper function on your date object to get the millisecond timestamp for that specific date, which is a JavaScript number data type. Useful for saving data in the backend of your application. For example Flask Peewee ORM requires a timestamp to be saved for the DateTimeField.

const [startDate, setStartDate] = useState(new Date())

<DatePicker
  onSelect( date => {
    setStartDate(getTime(date))
  }
/>

source: https://date-fns.org/v2.0.0-alpha.7/docs/getTime

Combine it with an effect to set the default state value to a timestamp on page load:

useEffect(() => {
    setStartDate(getTime(startDate))
  }, [])

Otherwise for your UI, you can use the format() helper function to get the string value of the given object, with any given format:

<h1>{format(startDate, "MMMM d, yyyy h:mm aa")}</h1>

Answer 5

Try this

<DatePicker 
   onChange={(value, e) => this.handleChange(value, e)}
   selected={this.state.inputValue} otherProps={here} 
/>

// you can access the value field in handleChange by e.target.value

handleChange(value, e) {
    console.log(value); // this will be a moment date object
    console.log(e.target.value); // this will be a string value in datepicker input field
}

Answer 6

If you want to get the new value (once the user clicks on a new date from DatePicker) pass the event to the method.

class MyComponent extends React.Component {
  constructor(props) {
    this.state = {inputValue: moment(),} // this will set the initial date to "today", 
                                         // you could also put another prop.state value there
    this.handleChange = this.handleChange.bind(this);
  }
  }


  handleChange(value) {
    console.log(value); // this will be a moment date object
    // now you can put this value into state
    this.setState({inputValue: value});
  }

  render(){
    ...
    <DatePicker 
       onChange={(event) => this.handleChange(event)}
       selected={this.state.inputValue} otherProps={here} />
    ...
  }
};
