JQuery / JavaScript MAC Address Validation

什么是 MAC 地址的正则表达式？
I would like to validate a string to ensure that it is a valid MAC Address.
我想验证一个字符串以确保它是一个有效的 MAC 地址。
Any ideas in Jquery or Javascript?
在 Jquery 或 Javascript 中有什么想法吗？
I have the following:
我有以下几点：
var mystring= '004F78935612' - This type of MAC Address
var rege = /([0-9a-fA-F][0-9a-fA-F]){5}([0-9a-fA-F][0-9a-fA-F])/;
alert(rege.test(mystring));
But its not all that accurate.
但它并不是那么准确。
Ie. My tissue box is a valid MAC Address?!?
IE。我的纸巾盒是有效的 MAC 地址？！？
Thanks!
谢谢！

Taking the regular expression from this question, you would implement it like so:
从这个问题中获取正则表达式，你会像这样实现它：
var mystring= 'Hello';
var regex = /^([0-9A-F]{2}[:-]){5}([0-9A-F]{2})$/;
alert(regex.test(mystring));
This regular expression searches for the beginning of the string ^, then TWO hexidecimal digits [0-9A-F]{2}, then a colon or dash [:-], five times over (...){5}, then a final group of TWO hexidecimal digits [0-9A-F]{2}, and finally the end of the string $.
这个正则表达式搜索字符串的开头^，然后是两个十六进制数字[0-9A-F]{2}，然后是一个冒号或破折号[:-]，五次以上(...){5}，然后是最后一组两个十六进制数字[0-9A-F]{2}，最后是字符串的结尾$。
Edit: in response to your comment, Pinch, that format is not considered a valid MAC address. However, if you wanted to support it, simply add a ?in the right place:
编辑：为了回应您的评论，Pinch，该格式不被视为有效的 MAC 地址。但是，如果您想支持它，只需?在正确的位置添加一个：
/^([0-9A-F]{2}[:-]?){5}([0-9A-F]{2})$/
// question mark ^ allows the colon or dash to be optional
