How can I use asp helper inside javascript script?

Question

I am rendering page layout inside javascript but I would like to use there some CMS helpers. Rendering works well but helpers doesn't work (I obtained "NaN" instead of text I wanted). How can I add helpers to javascript variable?

var detailsTemplate =
                    '<table cellspacing="0" cellpadding="0">' +
                         '<tr>' +
                               '<th class="info">' +
                                <%# CMS.GlobalHelper.ResHelper.GetString("ReceiptsList.ProductName") %> +
                                '</th>' +
                         '</tr>' +
                            '<tbody>' +
                                '{0}' +
                            '</tbody>' + 
                    '</table>' 

Answer 1

It works, I just add:

<span runat="server"> <js code..> </span>

and changed helper to (without single quotes):

<%= CMS.GlobalHelper.ResHelper.GetString("ReceiptsList.ProductName") %>

Answer 2

Set single quotation marks around the ASP tags:

'<th class="info">' +
  '<%# CMS.GlobalHelper.ResHelper.GetString("ReceiptsList.ProductName") %>' +
'</th>'

Look at the code generated and you will see, without the quotes you will have something like '<th>' + foo + '</th>' which will cause your current error. With the quotation marks you will have '<th>' + 'foo' + '</th>' which will run fine.
