html - html5输入类型数最大限制

Question

我对 html5 输入编号有一些疑问，输入类型编号的最大限制是多少

例如。

如果单击微调器后最大值大于 15 或 17，则会显示（数字末尾的 +16）。

第二个查询是 ios5 的 html5 的 datepicker 的事件是什么。

谢谢

我不知道您尝试了什么，但是没有为max属性指定限制，它可以是任何floating-point number

**Floating-point Number**
A floating-point number consists of the following parts, in exactly the following order:

    Optionally, the first character may be a "-" character.
    One or more characters in the range "0—9".
    Optionally, the following parts, in exactly the following order:
        a "." character
        one or more characters in the range "0—9"
    Optionally, the following parts, in exactly the following order:
        a "e" character or "E" character
        optionally, a "-" character or "+" character
        One or more characters in the range "0—9".
