我一直在按时间顺序对日期进行排序，但似乎没有起作用。
var data = JSON.parse(body);
_.sortBy(data,function(a){
return a.results;
});
然而我得到的输出仍然是错误的。最后几个条目不在正确的位置。正在读取的数据是这样的。

您需要对results进行排序，而不是对象本身。必须将sort函数或参数包装到数组中以使用_.sortBy。
sortedArray = _.sortBy(data.results, [function (a){
return a.date;
}]);
或
sortedArray = _.sortBy(data.results, ['date']);
var data = { count: 56, results: [{ date: "2014-06-05T18:02:51", id: "LC8_L1T_TOA/LC80370352014156LGN01" }, { date: "2014-06-21T18:02:55", id: "LC8_L1T_TOA/LC80370352014172LGN00" }, { date: "2014-07-07T18:03:03", id: "LC8_L1T_TOA/LC80370352014188LGN00" }, { date: "2014-07-23T18:03:05", id: "LC8_L1T_TOA/LC80370352014204LGN00" }, { date: "2014-08-08T18:03:14", id: "LC8_L1T_TOA/LC80370352014220LGN00" }, { date: "2014-08-24T18:03:17", id: "LC8_L1T_TOA/LC80370352014236LGN00" }, { date: "2014-09-09T18:03:21", id: "LC8_L1T_TOA/LC80370352014252LGN00" }, { date: "2014-09-25T18:03:18", id: "LC8_L1T_TOA/LC80370352014268LGN00" }, { date: "2014-10-11T18:03:25", id: "LC8_L1T_TOA/LC80370352014284LGN00" }, { date: "2014-10-27T18:03:23", id: "LC8_L1T_TOA/LC80370352014300LGN00" }, { date: "2014-11-12T18:03:26", id: "LC8_L1T_TOA/LC80370352014316LGN00" }, { date: "2014-11-28T18:03:24", id: "LC8_L1T_TOA/LC80370352014332LGN00" }, { date: "2014-12-14T18:03:18", id: "LC8_L1T_TOA/LC80370352014348LGN00" }, { date: "2014-12-30T18:03:14", id: "LC8_L1T_TOA/LC80370352014364LGN00" }, { date: "2015-01-15T18:03:14", id: "LC8_L1T_TOA/LC80370352015015LGN00" }, { date: "2015-01-31T18:03:10", id: "LC8_L1T_TOA/LC80370352015031LGN00" }, { date: "2015-02-16T18:03:01", id: "LC8_L1T_TOA/LC80370352015047LGN00" }, { date: "2015-03-04T18:02:56", id: "LC8_L1T_TOA/LC80370352015063LGN00" }, { date: "2015-03-20T18:02:46", id: "LC8_L1T_TOA/LC80370352015079LGN00" }, { date: "2015-04-05T18:02:35", id: "LC8_L1T_TOA/LC80370352015095LGN00" }, { date: "2015-04-21T18:02:34", id: "LC8_L1T_TOA/LC80370352015111LGN00" }, { date: "2015-05-07T18:02:18", id: "LC8_L1T_TOA/LC80370352015127LGN00" }, { date: "2015-05-23T18:02:16", id: "LC8_L1T_TOA/LC80370352015143LGN00" }, { date: "2015-06-08T18:02:26", id: "LC8_L1T_TOA/LC80370352015159LGN00" }, { date: "2015-06-24T18:02:32", id: "LC8_L1T_TOA/LC80370352015175LGN00" }, { date: "2015-07-10T18:02:43", id: "LC8_L1T_TOA/LC80370352015191LGN00" }, { date: "2015-07-26T18:02:49", id: "LC8_L1T_TOA/LC80370352015207LGN00" }, { date: "2015-08-11T18:02:53", id: "LC8_L1T_TOA/LC80370352015223LGN00" }, { date: "2015-08-27T18:03:00", id: "LC8_L1T_TOA/LC80370352015239LGN00" }, { date: "2015-09-12T18:03:07", id: "LC8_L1T_TOA/LC80370352015255LGN00" }, { date: "2015-09-28T18:03:13", id: "LC8_L1T_TOA/LC80370352015271LGN00" }, { date: "2015-10-14T18:03:13", id: "LC8_L1T_TOA/LC80370352015287LGN00" }, { date: "2015-10-30T18:03:19", id: "LC8_L1T_TOA/LC80370352015303LGN00" }, { date: "2015-11-15T18:03:19", id: "LC8_L1T_TOA/LC80370352015319LGN00" }, { date: "2015-12-01T18:03:21", id: "LC8_L1T_TOA/LC80370352015335LGN00" }, { date: "2015-12-17T18:03:21", id: "LC8_L1T_TOA/LC80370352015351LGN00" }, { date: "2016-01-02T18:03:18", id: "LC8_L1T_TOA/LC80370352016002LGN00" }, { date: "2016-01-18T18:03:18", id: "LC8_L1T_TOA/LC80370352016018LGN00" }, { date: "2016-02-03T18:03:15", id: "LC8_L1T_TOA/LC80370352016034LGN00" }, { date: "2016-02-19T18:03:06", id: "LC8_L1T_TOA/LC80370352016050LGN00" }, { date: "2016-03-06T18:03:05", id: "LC8_L1T_TOA/LC80370352016066LGN00" }, { date: "2016-03-22T18:02:58", id: "LC8_L1T_TOA/LC80370352016082LGN00" }, { date: "2016-04-07T18:02:50", id: "LC8_L1T_TOA/LC80370352016098LGN00" }, { date: "2016-04-23T18:02:43", id: "LC8_L1T_TOA/LC80370352016114LGN00" }, { date: "2016-05-09T18:02:46", id: "LC8_L1T_TOA/LC80370352016130LGN00" }, { date: "2016-05-25T18:02:50", id: "LC8_L1T_TOA/LC80370352016146LGN00" }, { date: "2016-06-10T18:02:54", id: "LC8_L1T_TOA/LC80370352016162LGN00" }, { date: "2016-06-26T18:03:01", id: "LC8_L1T_TOA/LC80370352016178LGN00" }, { date: "2016-07-12T18:03:09", id: "LC8_L1T_TOA/LC80370352016194LGN00" }, { date: "2016-07-28T18:03:13", id: "LC8_L1T_TOA/LC80370352016210LGN00" }, { date: "2016-08-13T18:03:15", id: "LC8_L1T_TOA/LC80370352016226LGN00" }, { date: "2016-08-29T18:03:23", id: "LC8_L1T_TOA/LC80370352016242LGN00" }, { date: "2016-09-14T18:03:26", id: "LC8_L1T_TOA/LC80370352016258LGN00" }, { date: "2016-09-30T18:03:27", id: "LC8_L1T_TOA/LC80370352016274LGN00" }, { date: "2016-04-30T18:08:59", id: "LC8_L1T_TOA/LC80380352016121LGN00" }, { date: "2016-05-16T18:08:57", id: "LC8_L1T_TOA/LC80380352016137LGN00" }] },
