Use the max attribute for inputs of type="number". It will specify the highest possible number that you may insert

对于type =“number”的输入使用max属性。它将指定您可以插入的最高编号

if you add both a max and a min value you can specify the range of allowed values:

如果同时添加最大值和最小值，则可以指定允许值的范围：

If, for user experience, you would prefer the user not to be able to enter more than a certain number, use Javascript/jQuery, as seen in this example

The maxlength attribute does not apply to an input of type="number"

maxlength属性不适用于type =“number”的输入

From W3 HTML5 spec concerning type="number"

从关于type =“number”的W3 HTML5规范

The following content attributes must not be specified and do not apply to the element: accept, alt, checked, dirname, formaction, formenctype, formmethod, formnovalidate, formtarget, height, maxlength, multiple, pattern, size, src, and width.

不得指定以下内容属性，并且不适用于该元素：accept，alt，checked，dirname，formaction，formenctype，formmethod，formnovalidate，formtarget，height，maxlength，multiple，pattern，size，src和width。

来源：http：//dev.w3.org/html5/spec/Overview.html#number-state-type-number（在簿记详情下）

In FF and IE, the input is falling back to be a text input and therefore, maxlength applies to the input. Once FF and IE implement type="number", they should also implement it in a way where maxlength does not apply.

在FF和IE中，输入回退为文本输入，因此maxlength适用于输入。一旦FF和IE实现type =“number”，它们也应该以maxlength不适用的方式实现它。

Max length will not work with the best way i know is to use oninput event to limit the maxlength. Please see the below code.
