Datetime Format Regex (MM/dd/yyyy) Javascript

I want to validate the date format on every keypress/keyup that the user's typed.

I've researched for what i'm trying to achieve. And I've found the solution here:

https://stackoverflow.com/questions/36009414/regex-to-validate-date-yyyy-mm-dd-while-typing-on-keyup 

(i was referring to @bobble bubble's answered)

but the format was YYYY-mm-dd. So, I tried to reverse to the format i was looking for to (MM/dd/yyyy).

But i cant get throught with validating every press that the user's typed. What happend was its validate as whole(regex) not one by one.

I also read his explanation about non-capturing group. But still, i can't get it.

 

Happy Coding!
