Question

I dont understand why the following code is not working. I save some inputs values to sessions. In the next page, I want users be able to copy these values to input fields.

$(function() {
$(“input#copyshipping”).click(function(){

    if ($("input#copyshipping").is(':checked'))

    {  
        // Checked, copy values  
        $("input#BillingFirstName").val("<%=Session("ShippingFIRSTNAME")%>");

        $("input#BillingLastName").val("<%=Session("ShippingLASTNAME")%>");

      $("input#BillingAddress1").val("<%=Session("ShippingADDRESS1")%>");

        $("input#BillingAddress2").val("<%=Session("ShippingADDRESS2")%>");

        $("input#BillingCity").val("<%=Session("ShippingCITY")%>");

      $("input#BillingState").val("<%=Session("ShippingSTATE")%>");

        $("input#BillingCountry").val("<%=Session("ShippingPOSTALCODE")%>");

      $("input#BillingPostalCode").val("<%=Session("ShippingCOUNTRY")%>");

    } else {  
        // Clear on uncheck  
        $("input#BillingFirstName").val("");  
      $("input#BillingLastName").val("");  
      $("input#BillingAddress1").val("");  
        $("input#BillingAddress2").val("");  
      $("input#BillingCity").val("");  
      $("input#BillingState").val("");  
        $("input#BillingCountry").val("");  
      $("input#BillingPostalCode").val("");

  }       });  });

Looking at the source code, it appears that the textboxes do not have id attributes, only name attributes. When you say, for example, $("input#BillingFirstName"), the “#” indicates an ID, and there isn’t one there.

Either add an id, or use $("input[name='BillingFirstName']). I recommend adding the id; it’s a faster selector.
