I want to retrieve value from text boxes to do validation.

However when I am trying to get value from a text box I get undefined value.

my code for button is :

<asp:LinkButton ID="lbLogin" runat="server" OnClientClick="Validation()" OnClick="btnLogin_Click" ValidationGroup="Submit">Login</asp:LinkButton>

text box is:

<asp:TextBox ID="tbPassword" runat="server" TextMode="Password" Width="124px"
CssClass="textbox"></asp:TextBox>

And function is :

function Validation() {
           var password = $("#tbPassword").val();
           alert(password);
       }

Alert always show "undefined". Is there anything wrong in my function?

Hey Try This

if u used master page then

C#

function Validation() {
                  
           var pwd = document.getElementById('cntPlcHolder_tbPassword').value;
           alert(pwd);
       }

other wise

XML

<pre lang="cs">function Validation() {

           var pwd = document.getElementById('tbPassword').value;
           alert(pwd);
       }</pre>

best luck
