allowNull and clearing value on keyup

[lqbwebParticipant]

Hi,

The normal behavior of the number input when the user selects the number and press Del is to reset the number to 0. Now, if I have allowNull option enabled, it makes sense to me to just clear it instead.

I am trying to implement this behavior, and half succeeded by writing my custom on-keyup event that checks for that, but there is a short instance where the user can see the input box going to 0 before going clear. I guess this is happening because your callback gets called before. Is there anyway to change this?

Thanks!

also, it seems to be an issue related. When you specify a minimum value, and you select all text and press Del, it still goes to 0, leaving the field invalid.

Hello lqbweb,

It’s difficult to figure out what exactly you’re trying to achieve and what purpose?
If I understand you right – you try to clear the input when fired ‘keyup’ event.

I have managed to do sort of what I was trying to do by overriding the ‘Delete’ function on the __proto__ of my number input instance, but I am afraid to be breaking some functionality.

What I want to achieve is make your number input not to reset the value to “0” when trying to delete the content, but to null (since the field, accepts nulls due to allowNull). This makes perfectly sense in the real world, since some of my number fields may be optional, and I do not want to display anything at all, and leave the user the option to clear its content.
