问题
It's strange. Input number is a standard for W3C, but it doesn't work on Firefox yet.
Is there some trick for using input number on Firefox?
回答1:
It's a proposed standard, not a standard. There's a difference.
There's no trick to it; it's just not supported yet on desktop Firefox (FirefoxOS and Firefox on Android may have an implementation; it's not clear to me whether they do).
