正则表达式验证 [英] Regular expression validation

问题描述

我想在验证中允许使用字母，空格和撇号。我正在使用以下表达式。我应该做些什么改变。



我尝试过的事情：

< asp：RegularExpressionValidator ID =REVOccrunat =serverControlToValidate =txtOccasionValidationExpression =^ [a-zA-Z] +（\s [a- zA-Z] +）？$
 ErrorMessage =不允许使用数字和特殊字符ForeColor =RedValidationGroup =SaveOccasion>< / asp：RegularExpressionValidator> 

解决方案

ErrorMessage =不允许使用数字和特殊字符ForeColor =RedValidationGroup =SaveOccasion>< / asp： RegularExpressionValidator>

您当前的正则表达式是：

- 从一个或多个ASCII字母字符开始

- 可选地后跟一个空白区域和一个或多个ASCII字母字符



对于您的请求，我只想将所有允许的字符添加到范围内：

^ [a-zA-Z \''] + 

I want to allow alphabets, white spaces and apostrophe in validation. I am using following expression. what will be the change I supposed to do .?

What I have tried:

<asp:RegularExpressionValidator ID= "REVOcc"  runat="server" ControlToValidate="txtOccasion" ValidationExpression="^[a-zA-Z]+(\s[a-zA-Z]+)?$"
                      ErrorMessage="No numbers and special characters are allowed" ForeColor="Red" ValidationGroup="SaveOccasion"></asp:RegularExpressionValidator>

解决方案

" ErrorMessage="No numbers and special characters are allowed" ForeColor="Red" ValidationGroup="SaveOccasion"></asp:RegularExpressionValidator>

Your current regex is:
- Begins with one or more ASCII alpha characters
- Optionally followed by a single white space and one or more ASCII alpha characters

For your request I would just add all allowed characters to the range:

"^[a-zA-Z\s']+

"
