concatenate for URL string

I want to concatenate Login+@+Server from the following javascript and pass it through the URL string.

 function SendMail(Login, Server) {
    urlStr = 'fileserver/#REQUEST.contentFolder#/sendemail.cfm'               
 </CFOUTPUT>, 'SendMail', 'Login + "@" + Server ,menubar=1,toolbar=0,location=0,directories=0,status=1,scrollbars=yes,resizable=1,copyhistory=1,width=400,height=270');
 My javascript code
 <a class="body" href="javascript:SendMail(John_Stern,')">John_Sterns</a></strong></p>

If you want to pass that in the URL you need to use something like ...

   var query = escape(Login + "@" + Server) + "?login=" + query, 'SendMail', 'menubar=1,toolbar=0,location=0,directories=0,status=1,scrollbars=yes,resizable=1,copyhistory=1,width=400,height=270');

Let me know if you have any questions or need more information.

You also have quote problems and should use onClick and return false on the link too (points to b0l)
  var urlStr = 'fileserver/#REQUEST.contentFolder#/sendemail.cfm'               
 function SendMail(Login, Server) {
  var query = escape(Login + "@" + Server); 
  var w ="?login="+query, 'SendMail','menubar,status,scrollbars,resizable,copyhistory,width=400,height=270');
  return (w)?false:true; // handle popup blockers
 <a class="body" href="pleaseEnableJavascript.html" 
onClick="return SendMail('John_Stern','')">John_Sterns</a></strong></p>
