Question

我在Parse后台工作中运行以下内容：

  var pushIncrement = Parse.Object.extend("pushIncrement");
  var pushIncrementQuery = new Parse.Query(pushIncrement);
  pushIncrementQuery.equalTo('objectId', 'hKj2Eazz6h');

  pushIncrementQuery.find({
    success: function(results) {
       console.log('Here are the results:' + results);
       status.success("Completed successfully.");
    },

    error: function(error) {
       console.log('shit');
       status.error('shitty shit');
    }
  });

results是一个Parse对象。例如，如果我正在查询所有matchCenterItem个对象，则会返回results，格式如下：

<matchCenterItem: 0x7f84e2c1a4b0, objectId: Je1VxP7dPw, localId: (null)> {
    categoryId = 9355;
    itemCondition = Used;
    itemLocation = US;
    maxPrice = 350;
    minPrice = 250;
    parent = "<PFUser: 0x7f84e2c20c10, objectId: kfEHfG4FUD>";
    searchTerm = "iphone 5 unlocked";
}

现在，如果我想访问categoryId的{{1}}属性并且控制台记录它，我该怎么做？我在成功函数中尝试了类似下面的内容，但它没有像我预期的那样工作：

results

想出来，可以这样做：

var pushIncrement = Parse.Object.extend("pushIncrement");
  var pushIncrementQuery = new Parse.Query(pushIncrement);
  pushIncrementQuery.equalTo('objectId', 'hKj2Eazz6h');

  pushIncrementQuery.find({
    success: function(results) {

      for (var i = 0; i < results.length; ++i) {
        var dayNumber = results[i].get("Number");
      }
       console.log('dem results be:' + dayNumber);
       status.success("Push Notifications completed successfully.");

    },

    error: function(error) {
       console.log('shit');
       status.error('shitty shit');
    }
  });

如何访问Parse对象属性？
