服务器标记的格式不正确-RegularExpressionValidator

本文关键字：不正确 -RegularExpressionValidator 格式 服务器 | 更新日期: 2023-09-27 18:23:51

我正在尝试编写一个RegularExpressionValidator，它检查以确保文本框中的条目是Integer（不包含"."或"，"，只有像"500"这样的整数值）

但我遇到了这个：

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？我到处找了找，找不到任何原因造成这种情况不好。

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

这部分。您的带引号的参数中有引号。

你可以通过将外引号做成单引号来绕过这一点：

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

另一个解决方案：转义html样式：

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

"

您的ErrorMessage属性格式不正确：

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

您需要转义属性值中的"，方法是将它们加倍：

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

或者，使用单引号分隔属性值：

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

试试这个

<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

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