$(".zanbtn").on("click",function(){ 
                var id = $(this).next().attr("title"); 
                var aval = $(this).next("a").html(); 
                $.getJSON('http://phpcms.com/index.php?m=mood&c=index&a=post&id=150-'+id+'-1&k=8&'+Math.random()+'&callback=?', function(data){ 
                  if(data.status==1) { 
                    console.log( $(this).next()); 
                    $("#zans"+id).html(data.data); 
                  }else { 
                    alert(data.data);
