用逗号输入数字jquery

Question

我在jquery中有一个奇怪的行为。

我想获得输入字段（类型号）的值。以示例显示它更容易。

当该值包含逗号时，函数将返回空字符串。

$("#input[type='number']").on('change',function() { 
      alert($(this).val()); 
     }); 

为什么？

在此先感谢

HTML5的spec不允许逗号：

value = floating-point number 
    A string representing a number 

floating-point numbe R：

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

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

一下添加到输入：步= “0.01”

所以像这样：

<input type="number" step="0.01" /> 

然后0.10将是有效的，我不确定如果您的操作系统使用逗号分隔逗号作为逗号将被视为有效。
