Answer 1

好像是bug在 Safari 。

从 github 中的讨论:

The sad truth is, that HTML5 forms features are fragmented. Safari 5.0.0 has included very odd support for interactive form validation, removed it in 5.0.2 and hasn't done anything for Safari 6

还有一个 ticket Safari 5.1，由 Paul Irish 创建

This conversation is about interactive validation feature.

Safari supports the required attribute. - correctly matches :invalid selector - input.validity.valueMissing correctly returns true for But form submission is not prevented because Safari has no interactive validation feature.

还有一个 ticket , 哪个状态 “不会修复”并从那里引用:

We disabled the interactive form validation feature because the implementation was incomplete and there were some compatibility issues.
