Question

HTML

<asp:TextBox ID="txtSasiNo" runat="server" Width="250px" MaxLength="17"></asp:TextBox>
<asp:RegularExpressionValidator CssClass="zorunlu" ValidationGroup="kaskoTeklifSayfasi" Display="Dynamic" ID="rangevalidator1" runat="server" SetFocusOnError="true" ControlToValidate="txtSasiNo" ErrorMessage="Enter number characters only (8 or 17)" ValidationExpression="^\d{8}$|^\d{17}$""></asp:RegularExpressionValidator>
<asp:RequiredFieldValidator ID="rfvSasiNo" SetFocusOnError="true" ValidationGroup="kaskoTeklifSayfasi" runat="server" Display="Dynamic" ControlToValidate="txtSasiNo" CssClass="zorunlu">Please enter Number.</asp:RequiredFieldValidator>

如果值低于确定

12345678    // This is 8 characters
12345678901234567    // This is 17 characters

但是，如果值不正确

1 // 1 characters

123456 // 6 characters 

123456789 // 9 characters 

1234567890123456 // 16 characters

RegularExpressionValidator 仅应适用于 8个字符和 17个字符

如果尝试以下

<asp:RegularExpressionValidator CssClass="zorunlu" ValidationGroup="kaskoTeklifSayfasi" Display="Dynamic" ID="rangevalidator1" runat="server" SetFocusOnError="true" ControlToValidate="txtSasiNo" ErrorMessage="Enter number characters only (8 or 17)" ValidationExpression="^\d{8}$|^\d{17}$""></asp:RegularExpressionValidator>

或

如果我尝试下面

<asp:RegularExpressionValidator CssClass="zorunlu" ValidationGroup="kaskoTeklifSayfasi" Display="Dynamic" ID="rangevalidator1" runat="server" SetFocusOnError="true" ControlToValidate="txtSasiNo" ErrorMessage="Enter number characters only (8 or 17)" ValidationExpression="^([0-9]{8})|([0-9]{17})$"></asp:RegularExpressionValidator>

这些对我不起作用。

我错过代码？

Answer 1

RegularExpressionValidator中有一个错误。尝试从"

中删除一个ValidationExpression="^\d{8}$|^\d{17}$""

请参阅更新的代码： -

<asp:TextBox ID="txtSasiNo" runat="server" Width="250px" MaxLength="17"></asp:TextBox>
<asp:RegularExpressionValidator CssClass="zorunlu" ValidationGroup="kaskoTeklifSayfasi" Display="Dynamic" ID="rangevalidator1" runat="server" SetFocusOnError="true" ControlToValidate="txtSasiNo" ErrorMessage="Enter number characters only (8 or 17)" ValidationExpression="^\d{8}$|^\d{17}$"></asp:RegularExpressionValidator>

<asp:RequiredFieldValidator ID="rfvSasiNo" SetFocusOnError="true" ValidationGroup="kaskoTeklifSayfasi" runat="server" Display="Dynamic" ControlToValidate="txtSasiNo" CssClass="zorunlu">Please enter Number.</asp:RequiredFieldValidator>

它正在发挥作用。

Asp.net RegularExpressionValidator用于特定数字
