IE7上的电子邮件验证问题REGEX [英] Email validation problem REGEX on IE7

问题描述

我有一个IE7特殊REGEX问题.
我正在使用以下正则表达式验证电子邮件地址:

Hi, I have an IE7 spesific REGEX problem.
I''m validating Email Address with the following regex:

^\s*[a-zA-Z0-9_\+-]{1,63}(\.[a-zA-Z0-9_\+-]{1,63})*@(?=[a-zA-Z0-9-\.]{0,255}\.?\s*$)[a-zA-Z0-9-]{1,63}(\.[a-zA-Z0-9-]{1,63}){0,126}\.([a-zA-Z]{2,63})\.?\s*$

这适用于所有现代浏览器，但IE7(支持客户想要扩展到页面的浏览器)不适用于[e-mail]

我在IE7中阅读了有关?=之类的前瞻性问题，但建议的更改似乎不起作用?是否有任何正则表达式大师都对如何使IE 7正常工作并在更现代的浏览器版本中保持功能没有任何想法.

This works every modern browser but IE7 (which support customer wants to extend to the page) does not work with f.e [e-mail]

I read about lookahead like "?=" being problem in IE7 but suggested changes do not seem to work? Does any regex guru has any ideas how to get this work with IE 7 and still keep it functional in more modern browser versions.
