Question

I want to apply javascript email validation in my project so please some suggest me the exact code for that because i just want to apply it only for regular expression and i don’t want to add any plug in for it. is it possible to write some code in source file and apply to email field.

Thanks in advance

Answer 1

you can add a regular expression validator to validate you email.

<asp:TextBox ID="txtEmailAddress" runat="server" ></asp:TextBox>
                        <asp:RegularExpressionValidator ID="valRegExEmail" runat="server" ControlToValidate="txtEmailAddress"
                            Display="None" ErrorMessage="Please give a valid email address" ValidationGroup="StaffAddValidation" ValidationExpression="^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z\.][a-zA-Z]{1,3}$"></asp:RegularExpressionValidator>
