服务器标记格式不正确-RegularExpressionValidator

Question

我正在尝试编写一个RegularExpressionValidator，以检查以确保进入文本框的条目是Integer（不包含“。”或“，”，仅包含“ 500”之类的整数值）

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>

这是什么问题？ 我四处搜寻，找不到任何无法正常形成的原因。

Answer 1

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

这部分。 您带引号的参数中有引号。

您可以通过使外部引号成为单引号来解决此问题：

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

另一个解决方案：转义html样式的引用：

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

“

Answer 2

您的ErrorMessage属性格式不正确：

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

你需要躲避" ，在属性值-做他们加倍：

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).'

Answer 3

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> 

要么

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