ASP.NET普通防爆pression验证器不工作在Internet Explorer 7 [英] ASP.NET Regular Expression Validator Not Working on Internet Explorer 7

问题描述

我使用下面的正前pression验证，以确保密码输入符合1上的情况下，1低的情况下，1号的要求，并允许1特殊字符：

I am using the following Regular Expression Validator to ensure the password enter meets the requirements of 1 upper case, 1 lower case, 1 number, and 1 allowed special character:

    <asp:RegularExpressionValidator ID="rev_txtNewPassword" runat="server" Display="Dynamic"
    ErrorMessage=" Password does not meet requirements" ControlToValidate="txtNewPassword" ValidationGroup="password"
    ValidationExpression="^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[!@#$%^&*]).{8,16}$"></asp:RegularExpressionValidator>

这工作在火狐，Chrome，Safari浏览器，Internet Explorer 8和9，它只是没有在Internet Explorer 7的工作不管是什么输入到密码框，它说，它不符合要求。这是一个自定义的SharePoint 2010 Web部件的一部分。

This works in FireFox, Chrome, Safari, Internet Explorer 8 and 9. It just doesn't work on Internet Explorer 7. No matter what is entered into the password box, it says it doesn't meet the requirements. This is part of a custom SharePoint 2010 web part.

任何想法，为什么除权pression验证不仅是在IE7的工作？

Any ideas why the expression validator isn't working only on IE7?

感谢
