Hi Franky,
many thanks for the implementation. I checked it on my staging web server with Chrome and Opera and it works. Safari seems not to support (although it was mentioned to do so), Firefox and SeaMonkey do not support it as expected but the field is treated (and expected to work) as a text field at these browsers.
I just would add a link to examples for the:
“For HTML5 fields, you can here enter the pattern that the entered value should have.”
Maybe a link to: http://html5pattern.com/Dates?
Cool at least an beneficial add on to supported browsers. I bet once in the future all browser will fully support HTML5 (let’s dream) 😉
Cheers and thanks again!
Joerg
