asp.net - ASP :NET Confirm Password field

Question

我正在 asp.net 中创建一个简单的注册表单。这是我的问题:如果我的确认密码字段为空，它仍然会提交表单。我正在使用compareToValidate，我还需要使用requiredvalidator吗？我是 ASP.NET 的新手，但如果假设密码是 123 并且确认密码为空，comparevalidator 不应该生成错误。

        <fieldset>
       <legend>Enter your data</legend>
       <table>
        <tr>
       <td align="right">User Name :</td>
       <td>&nbsp;</td>
         <td align="left">
        <asp:TextBox ID="tbUsername" runat="server"></asp:TextBox>
    <asp:RequiredFieldValidator ID="rfvUserName" runat="server" 
        ControlToValidate="tbUsername" 
        CssClass="ValidationError"
        ErrorMessage="&laquo; (Required)"
        ToolTip="User Name is a REQUIRED field"
        ></asp:RequiredFieldValidator>
        </td>
</tr>`enter code here`
<tr >
<td align="right">Password&nbsp;:&nbsp;</td>
<td>&nbsp;</td>
<td align="left"> 
    <asp:TextBox ID="tbPassword" runat="server" TextMode="Password"></asp:TextBox>
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
     ErrorMessage="&laquo; (Required)" 
     ControlToValidate="tbPassword"
     CssClass="ValidationError"

    ToolTip="Password is a REQUIRED field"
    ></asp:RequiredFieldValidator>
</td>

</tr>
<tr >
<td align="right">Confirm Password&nbsp;:&nbsp;</td>
<td>&nbsp;</td>
<td align="left"> 
    <asp:TextBox ID="ConfirmPass" runat="server" TextMode="Password"></asp:TextBox>
     <asp:CompareValidator ID="CompareValidator1" runat="server" 
     ControlToValidate="ConfirmPass"
     CssClass="ValidationError"
     ControlToCompare="tbPassword"
     ErrorMessage="No Match" 
     ToolTip="Password must be the same" />

</td>

</tr>

您还必须提供所需的验证器!比较验证器只会将值与目标控件进行比较并提醒用户。

<td align="left"> 
    <asp:TextBox ID="ConfirmPass" runat="server" TextMode="Password"></asp:TextBox>

    <asp:CompareValidator ID="CompareValidator1" runat="server" 
     ControlToValidate="ConfirmPass"
     CssClass="ValidationError"
     ControlToCompare="tbPassword"
     ErrorMessage="No Match" 
     ToolTip="Password must be the same" />

    <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" 
     ErrorMessage="&laquo; (Required)" 
     ControlToValidate="ConfirmPass"
     CssClass="ValidationError"
     ToolTip="Compare Password is a REQUIRED field">
    </asp:RequiredFieldValidator>
</td>

希望这对您有帮助!
