Getting the date from a Bootstrap React form

Question

How do I extract a yyyy-mm-dd timestamp from the following?

handleDateChange = e => {}

<Form.Group as = {Col}>
  <Form.Control
    type = "date"
    value = { this.state.closingDate }
    onChange = { this.handleDateChange }
  />
</Form.Group>

At the moment e.timeStamp gives me a four or five digit number.

Answer 1

Try this:

  handleDateChange = e => {
    const date = new Date(e.target.value);
    const timestamp = date.getTime();

    console.log(timestamp)

    this.setState({
      closingDate: e.target.value
    })
  }
