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.
