Common Examples

import { DateFieldYearless } from "@servicetitan/anvil2";

function ExampleComponent() {
  return <DateFieldYearless defaultValue={{ month: 3, day: 22 }} />;
}

Default values

Default values can be included in DateFieldYearless to use the field in an uncontrolled mode.

Controlled usage

The DateFieldYearless can be controlled. This means you can maintain the state outside the component. Listen for new dates with onChange and supply a date into the value prop.

Validation

Understanding the object passed back in onChange is key to understanding how to validate this field.isValid will tell you if the field can be parsed into a valid month and day and if it meets the criteria of minDate, maxDate, required, and unavailable.isInputValid will tell you only if the underlying input is parseable into a month and a day — this does not consider whether the date is good according the other props.isInputEmpty will tell you if the underlying input has no digits entered.

Disabled hint text

The hint text can be disabled. If the hint text is disabled, ensure that the date format is displayed on the page.
