Asp.net RegularExpressionValidator用於特定數字

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>

如果值如下確定

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

但是如果以下值不正確

1 // 1 characters

123456 // 6 characters 

123456789 // 9 characters 

1234567890123456 // 16 characters

RegularExpressionValidator 僅適用於8個字符和17個字符

如果嘗試以下

<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>

要么

如果我嘗試以下

<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="^([0-9]{8})|([0-9]{17})$"></asp:RegularExpressionValidator>

這些對我不起作用。

我在哪里錯過代碼？

Answer 1

您在RegularExpressionValidator犯了一個錯誤。 嘗試去除一個"從ValidationExpression="^\\d{8}$|^\\d{17}$""

查看更新的代碼：-

<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>

這是工作。
