HTML5中是否有minlength驗證屬性？ - Is there a minlength validation attribute in HTML5?

問題：

It seems the minlength attribute for an <input> field doesn't work. 彷佛<input>字段的minlength屬性不起做用。

Is there any other attribute in HTML5 with the help of which I can set the minimal length of a value for fields? HTML5中是否還有其餘屬性能夠幫助我設置字段值的最小長度？
