使用jQuery遍历JSON

Question

This is response from my php script:

[{"name":"sss","vote_up":2,"vote_down":0,"report":2},{"name":"sdsad","vote_up":2,"vote_down":0,"report":2},{"name":"sssssss","vote_up":2,"vote_down":0,"report":2},{"name":"sssssss","vote_up":2,"vote_down":0,"report":0},{"name":"sss","vote_up":1,"vote_down":0,"report":1},{"name":"TEST","vote_up":1,"vote_down":0,"report":1},{"name":"asdsa","vote_up":1,"vote_down":0,"report":0},{"name":"ssssssssss","vote_up":1,"vote_down":0,"report":0},{"name":"TEEST","vote_up":1,"vote_down":0,"report":0},{"name":"sssssssssssssssssssss","vote_up":1,"vote_down":1,"report":1},{"name":"asdsadsa","vote_up":1,"vote_down":0,"report":1},{"name":"KOmentar","vote_up":1,"vote_down":0,"report":1},{"name":"ssssssssss","vote_up":0,"vote_down":1,"report":1}]

how can I catch that data with jQuery, here is my try but not working:

 $.ajax({
            method:"POST",
            url:"/bylikes",
            data:{task:true,comment:commentID,reply:replyID},
            success: function( data ){
                repObj = JSON.parse(data);
                 $.each(repObj,function(index,item){
                    alert(item.name+ " - "+item.report)
                 }); 
               //$('#fullList').html(""+data+"");
            }


    });
