string
Name
Description

Identifies the field when a form is submitted.

Type

The uncontrolled value of the field when it’s initially rendered.

onValueChange
function
Description

Callback fired when the number value changes.

The eventDetails.reason indicates what triggered the change:

  • 'input-change' for parseable typing or programmatic text updates
  • 'input-clear' when the field becomes empty
  • 'input-blur' when formatting (and clamping, if enabled) occurs on blur
  • 'input-paste' for paste interactions
  • 'keyboard' for keyboard input
  • 'increment-press' / 'decrement-press' for button presses on the increment and decrement controls
  • 'wheel' for wheel-based scrubbing
  • 'scrub' for scrub area drags
Type
onValueCommitted
function
Description

Callback function that is fired when the value is committed. It runs later than onValueChange, when:

  • The input is blurred after typing a value.
  • The pointer is released after scrubbing or pressing the increment/decrement buttons.

It runs simultaneously with onValueChange when interacting with the keyboard.

Warning: This is a generic event not a change event.

Type
allowOutOfRange

false
Description

When true, direct text entry may be outside the min/max range without clamping, so native range underflow/overflow validation can occur. Step-based interactions (keyboard arrows, buttons, wheel, scrub) still clamp.
