you can do this

var txtUsernameID = '<%= txtUsername.ClientID %>';
than 
txtUserNameId = '#' + txtUserNameId;
var val = $(txtUserNameId).val();

You can't. Existingvalues exists on the client-side (the users browser) so you would need to pass it to the server-side somehow.

You can do this either by sending it as a query string parameter or saving it in a hidden field and doing a postback.

Use hidden variable and store Existingvalues values and get that value in code behind client side:

$("#hdExistingvalues").val(Existingvalues);

Code behind:

string str =hdExistingvalues.value;
