js操作map集合按key排序
Json传到前到的数据如下 ：
[
{"unitdesc":" 作品为主，同时兼备***馆的各项功能。",
"unitheatTotal":0,
"unitcoldTotal":1176.02,
"unitwaterTotal":0,
"unitpicturename":"",
"datas":{"2016":["8251.41","7075.39","0.0","0.0","0.0","1176.02","0.0"],"2015":"0.0","0.0","0.0","0.0","0.0","0.0","0.0"],
"2010":"80.0","0.0","0.0","0.0","0.0","0.0","0.0"],"2018":"900","0.0","0.0","0.0","0.0","0.0","0.0"]},
"unitairTotal":0,
"unitelectricTotal":7075.39,
"unitname":"关伙馆",
"unitotherTotal":0,
"unitId":0,
"id":666666,
"unitTotal":8251.4},
{"unitdesc":" 队**层群众文化建设，活跃群众文化生活***军的作用。",
"unitheatTotal":0,
"unitcoldTotal":0,
"unitwaterTotal":0,
"unitpicturename":"",
"datas":{"2016":["4618.09","4618.09","0.0","0.0","0.0","0.0","0.0"],"2015":["0.0","0.0","0.0","0.0","0.0","0.0","0.0"],
"2010":"400","0.0","0.0","0.0","0.0","0.0","0.0"],"2018":"980","0.0","0.0","0.0","0.0","0.0","0.0"]},
"unitairTotal":0,
"unitelectricTotal":4618.08984375,
"unitname":"燕学处",
"unitotherTotal":0,
"unitId":0,
"id":666667,
"unitTotal":4618.08984375
}
]
现在要把集合中每个对象的属性为datas（map集合）的值。按Ｍap中的key 从小到大的顺序排列。；
ajax成功后的解析上面的数据-----------（Highchart中）---------
