我正在尝试编写一个 RegularExpressionValidator 来检查以确保进入文本框的条目是整数（不包含“。”或“，”，只有整数值，如“500”）

但是我遇到了这个：

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: The server tag is not well formed.

代码如下：

<asp:TextBox ID="Paymenttb" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID ="PaymentValidator" runat="server" ControlToValidate="Paymenttb" 
ErrorMessage="Payment must be of type Int (No "." or "," for example)." ValidationExpression="^\d+$">*</asp:RegularExpressionValidator>

这有什么问题？我已经四处寻找，找不到任何原因导致这种情况没有很好地形成。

ErrorMessage="Payment must be of type Int (No "." or "," for example)."

这部分。您在引用的参数中有引号。

您可以通过将外部引号设为单引号来解决此问题：

ErrorMessage='Payment must be of type Int (No "." or "," for example).'

另一种解决方案：转义引用html样式：

ErrorMessage="Payment must be of type Int (No &quot;.&quot; or &quot;,&quot; for example)."

尝试这个

<asp:TextBox ID="Paymenttb" runat="server"></asp:TextBox>


<asp:RegularExpressionValidator ID ="RegularExpressionValidator1" runat="server" ControlToValidate="Paymenttb"  ToolTip="Payment must be of type Int (No '.' or ',' for example)." ValidationExpression="^\d+$">*</asp:RegularExpressionValidator>

或者

<asp:RegularExpressionValidator ID ="PaymentValidator" runat="server" ControlToValidate="Paymenttb"  ErrorMessage="Payment must be of type Int (No '.' or ',' for example)." ValidationExpression="[0-9]"></asp:RegularExpressionValidator>

您的ErrorMessage属性格式不正确：

ErrorMessage="Payment must be of type Int (No "." or "," for example)."

您需要"在属性值中转义 - 通过将它们加倍来做到这一点：

ErrorMessage="Payment must be of type Int (No ""."" or "","" for example)."

或者，使用单引号来分隔属性值：

ErrorMessage='Payment must be of type Int (No "." or "," for example).'
