如何在 Material-UI TextField 中设置当前日期

Question

If I set type="date" on a TextField I can initialise it with a string.

https://codesandbox.io/s/9y6yz462op

const values = {
  someDate: "2017-05-24"
};

function App() {
  return (
    <div className="App">
      <TextField
        name="someDate"
        label="Some Date"
        InputLabelProps={{ shrink: true, required: true }}
        type="date"
        defaultValue={values.someDate}
      />
    </div>
  );
}

However, when I try to use the current date using a date object

const values = {
  someDate: new Date()
};

I get an error

Warning: Failed prop type: Invalid prop `defaultValue` supplied to `TextField`.

How do I pass a Date to the TextField?

As you can read in the docs defaultValue has to be either a string or a number . The Date type is not supported.

But since you're using type="date" you should be fine by handing the date as string.

eg

const values = {
  someDate: new Date().toISOString().substring(0, 10);
};
