Is it okay to use <input type="tel"/> now?

I'm working on a mobile phone web app and I have several text fields that could benefit from <input type="tel"/>. iPhones wi开发者_Go百科ll adjust the keyboard for the user, but I'm worried about breaking backwards compatibility. What I'm hoping is that browsers/phone that support this can assist the user and other browser will fall back to a standard text field? Is this an acceptable practice? Does it even work?

Yes, any unsupported type will revert to the 'type=text' format.

I found a good page which lists out all the existing input types. I tried looking at it from different browsers, a bit interesting. Don't know if it will help you or not.

Browsers will fall back to type="text" when they encounter unsupported input type. So I think it's OK to use type="tel".

Short answer: yes. As @el.pescado mentions, browsers fall back to type=text when they don't understand the type. For more info about the other cool features you get from HTML5 forms, check out A Form of Madness, which is the forms chapter in Dive Into HTML5.

It is ok. Browsers will use type=text when they encounter unsupported types.
