Question

I have two labels: username and email. I use them to retrieve their content and pass them as method parameters.

var lblEmail = $get('<%= lblEmail.ClientID %>'); var email = lblEmail.innerText;  var lblUsername = '<%= lblUsername.ClientID %>'; var username = lblUsername.innerText; 

The email label is defined in the same way as username label does, but for this last I can’t get the value, innertext returns undefined.

…

<td class='inputField'> <table cellpadding='0' cellspacing='0' border='0'> <tr> <asp:Label ID='lblUsername' CssClass='font1' runat='server'/> </tr> </table> </td> 

…

... <td class='inputField'> <table cellpadding='0' cellspacing='0' border='0'> <tr> <td> <asp:Label runat='server' ID='lblEmail' CssClass='font1' /> </td> ... 

What could be a possible reason to justify what is happening? How can I solve this problem? I’m seeing on the page both label values, I set them on the same place (when page loads).

Answer 1

Because you defined only the client ID for the userName label :

var lblEmail = $get('<%= lblEmail.ClientID %>'); var email = lblEmail.innerText;  var lblUsername = '<%= lblUsername.ClientID %>'; var username = lblUsername.innerText;
