jQuery技术:访问json对象的最佳或正确方法？

我有以下格式的json响应：

[ { "0": [ { "tVote": "32" } ], "1": [ { "choice": "Barcelona", "tbAns": "2" }, { "choice": "Bayern Muenchen", "tbAns": "2" }, { "choice": "Juventus", "tbAns": "20" }, { "choice": "Manchester United", "tbAns": "5" }, { "choice": "Real Madrid", "tbAns": "3" } ], "2": [ { "question": "Favorite football team ?" } ], "status": "positive", "msg": "Thank you, your vote has been count." } ] 

到目前为止，我在以下代码中使用jQuery ajax访问它：

 $(function() { $('.vote').click( function(e) { e.preventDefault(); var parId = $(this).closest('form').attr('id'); var itemId = $(this).prev('input[name=q_id]').val(); var formAction = $('#' + parId).attr('action'); $.ajax({ type : 'POST', url : formAction, data : $('#' + parId + '').serializeArray(), dataType : 'json', beforeSend: function() { $('.loadPoll-' + itemId).removeClass('hidden'); }, error : function(request, status, error) { $('#' + parId).html('sorry can't send your request, please try again later
' + status + ' ' + error); }, success : function(data) { $('.loadPoll-' + itemId).addClass('hidden'); $.each(data, function() { var theQ = data[0][2][0]['question']; var msg = data[0]['msg']; var status = data[0]['status']; var totalVoter = data[0][0][0]['tVote']; var item = data[0][1]; var itemLength = data[0][1].length; var itemChoice = data[0][1][0].choice; var parental = $('.vote:focus').closest('form').attr('id'); //create html template for response var template = '
'; if(status === 'negative') { $.amaran({ content : { bgcolor: '#FF9900', message: msg, color : '#fff', icon : 'fa fa-download' }, theme : 'colorful', position : 'bottom right', cssanimationIn : 'swing', cssanimationOut: 'bounceOut' }); template += '
' + theQ + '
Total voter: ' + totalVoter + '
