        return true;
    }
 }
 function IsAlpha() {
     var key = window.event.keycode;

<tr>
                    <td align="right" style="width:20%">MOBILE NO.</td>
                    <td class="style3"><asp:TextBox ID="TXT_M_NO" class="txt" runat="server" onkeypress="return isNumberKey()" BackColor="lightyellow"></asp:TextBox>
                    </td>
                    <td colspan="2"></td>
               </tr>

<tr>
                     <td align="right" class="style2" style="width:20%">
                     <span style="color:Red;">*</span> EMPLOYEE NAME </td>
                     <td class="style1"><asp:TextBox ID="TXTEMP_NAME" class="txt" runat="server" onkeypress="return IsAlpha()" BackColor="lightyellow"></asp:TextBox>
                     </td>
                    <td align="right" style="width:10%">LAST NAME</td>
                    <td><asp:TextBox ID="TxtLnm" class="txt" runat="server" onkeypress="return IsAlpha()" BackColor="lightyellow"></asp:TextBox>
                    </td>
                </tr>

这两个验证功能不起作用

请让我知道如何它将工作

These two function of validation is not working
please let me know how it will work

推荐答案

使用asp自定义验证器，如下所示：

ASP CustomValidator



的CustomValidator。 ClientValidationFunction属性



除客户端外，还应包括服务器端验证。

Use an asp custom validator as follows:
ASP CustomValidator

CustomValidator.ClientValidationFunction Property

Besides client side, should also include server side validation as well.
