[jQuery] Urgent "&" problem in wordpress

[Rupak]

Hi all
I am new to wordpress.I am using  $.ajax

$.ajax({
   type: "POST",
   url: "some.php",
   data: "name=John&location=Boston",
   success: function(msg){
     alert( "Data Saved: " + msg );
   }
 });

But it will convert  "&" into "&#038".

can any one tell me how to fixed this.
