When i receive this JSON data using jQuery, it shows correctly in my alert(), 
But when i use jQuery append() or html(), then it does not work, specially the
following html values becomes empty.

1. <span class=\"hide\">5<\/span>   
2. <span class=\"single_user_username\">1003<\/span> (<span class=\"single_user_status\">waiting<\/span>)


JQuery:
=========
        $.ajax({
          type    : "GET",//POST
          dataType: 'json',
          url     : url,
          data    : datas,
          async   : true,
          beforeSend: function(){ajaxon();},
          complete: function(){ajaxoff();},
          success : function(msg)
          {
            alert(msg.result);
            //$(render).empty().append(msg.result); // same result 
            $(render).html(msg.result);
          }          
        });

PHP returned json packets
