Notes

Per issues #21158, #17344, #9421, and documentation about inputs, it appears this community does not support native inclusion of the type="number" in the <Input /> attributes, so please feel free to include it as needed, and be aware that it is heavily suggested that server side validation be utilized, as client side validation can be edited by power users.

FAQ

Why value can exceed min or max in control?

Developer handle data by their own in control. It will make data out of sync if InputNumber change display value. It also cause potential data issues when use in form.

Why dynamic change min or max which makes value out of range will not trigger onChange?

onChange is user trigger event. Auto trigger will makes form lib can not detect data modify source.

Why onBlur or other event can not get correct value?

InputNumber's value is wrapped by internal logic. The event.target.value you get from onBlur or other event is the DOM element's value instead of the actual value of InputNumber. For example, if you change the display format through formatter or decimalSeparator, you will get the formatted string in the DOM. You should always get the current value through onChange.

Why changeOnWheel unable to control whether the mouse scroll wheel changes value?

The use of the type attribute is deprecated

The InputNumber component allows you to use all the attributes of the input element and ultimately pass them to the input element, This attribute will also be added to the input element when you pass in type='number', which will cause the input element to trigger native properties (allowing the mouse wheel to change the value), As a result changeOnWheel cannot control whether the mouse wheel changes the value.
