Methods

MethodDescription
validate( (value: string )): boolean

Validates a user input string according to the current locale and format options. Values can be partially entered, and may be valid even if they cannot currently be parsed to a number. Can be used to implement validation as a user types.

setInputValue( (val: string )): voidSets the current text value of the input.
commit(): void

Commits the current input value. The value is parsed to a number, clamped according to the minimum and maximum values of the field, and snapped to the nearest step value. This will fire the onChange prop with the new value, and if uncontrolled, update the numberValue. Typically this is called when the field is blurred.

increment(): voidIncrements the current input value to the next step boundary, and fires onChange.
decrement(): voidDecrements the current input value to the next step boundary, and fires onChange.
incrementToMax(): voidSets the current value to the maxValue if any, and fires onChange.
decrementToMin(): voidSets the current value to the minValue if any, and fires onChange.
