Knockout binding issue only in FireFox

[Evan Larsen]

Hello, I created a very simple JS fiddle to illustrate my problem.

https://jsfiddle.net/evanlarsen/e8bj9upf/6/

If you open the above jsFiddle in Chrome and type in the textbox then everything works as expected but if you open it in Firefox then Firefox is dropping the last letter of whatever you type.

Can anyone please explain to me what I am doing wrong and how I can resolve this issue with firefox?

Thank you!

Sorry, I think the knockout library wasn't included correctly in the jsfiddle. here is an updated jsfiddle.

Seems like the afterkeydown event works little differently on Firefox. Not sure if it is a bug or something else.

Your choices are to either use a different event (valueUpdate: 'input' seems to work), or use textInput binding: https://stackoverflow.com/questions/43812877/input-type-number-binding-issue-with-knockout-in-firefox/43820869#43820869

I would go with the second option, since with the events you cannot be sure that it will work with all browsers

+1.  See also Note 1 here: <https://knockoutjs.com/documentation/value-binding.html>
