如何使正则表达式特殊字符可以接受？ [英] how to make regular expression special character acceptable ?

问题描述

我有一个正则表达式，不接受特殊字符

我也想删除空格字符

PLZ帮助？

 <   asp：RegularExpressionValidator     ID   =  RegularExpressionValidator4    runat   =  server  
   
                                                                                 ErrorMessage   = 最少6 charecters  
   
   
   
                                      < span class =code-attribute>                                           ValidationExpression   =  ^ [a-zA-Z0-9 \ t] {6,20} $  
   
                                                                      < span class =code-attribute>           ControlToValidate   =  txtUsername    ForeColor   = 红色  
   
                                 ValidationGroup   =  1 >  
 <   p     class   =  rfv > 最少6个字符<   / p  >  
 
 < span class =code-keyword><   / asp：RegularExpressionValidator  >  

解决方案

ControlToValidate = txtUsername ForeColor = 红色

ValidationGroup = 1 >
< p class = rfv > 最少6个字符< / p >

< / asp：RegularExpressionValidator >

基本上，你想要除空格之外的任何角色，对吧？试试这个：

 ^ [^ \s] {6,20} 

i have a regular expression which is not accepting special characters
and i wants remove space charecter too
plz help ?

<asp:RegularExpressionValidator ID="RegularExpressionValidator4" runat="server"

                                       ErrorMessage="Minimum 6 charecters"



                                       ValidationExpression="^[a-zA-Z0-9\s]{6,20}$"

                                       ControlToValidate="txtUsername" ForeColor="Red"

               ValidationGroup="1">
                <p class="rfv">Minimum 6 Characters</p>

                                       </asp:RegularExpressionValidator>

解决方案

" ControlToValidate="txtUsername" ForeColor="Red" ValidationGroup="1"> <p class="rfv">Minimum 6 Characters</p> </asp:RegularExpressionValidator>

Basically, you want any character except space, right? Try this:

^[^\s]{6,20}
