原始数据：
[{"Group":1,"Groupheader":"质量管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""}, {"Group":1,"Groupheader":"","Leftimg":"","Left":"","Min":"质量巡检","Right":"","Rightimg":""}, {"Group":2,"Groupheader":"设备管理","Leftimg":"","Left":"","Min":"","Right":"","Rightimg":""}, {"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"设备专业点检","Right":"","Rightimg":""}, {"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"设备日检","Right":"","Rightimg":""}, {"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"设备周检","Right":"","Rightimg":""}, {"Group":2,"Groupheader":"","Leftimg":"","Left":"","Min":"设备月检","Right":"","Rightimg":""}];
处理后的数据：
[ { "Group": 1, "data": [ { "Group": 1, "Groupheader": "质量管理", "Leftimg": "", "Left": "", "Min": "", "Right": "", "Rightimg": "" }, { "Group": 1, "Groupheader": "", "Leftimg": "", "Left": "", "Min": "质量巡检", "Right": "", "Rightimg": "" } ] }, { "Group": 2, "data": [ { "Group": 2, "Groupheader": "设备管理", "Leftimg": "", "Left": "", "Min": "", "Right": "", "Rightimg": "" }, { "Group": 2, "Groupheader": "", "Leftimg": "", "Left": "", "Min": "设备专业点检", "Right": "", "Rightimg": "" }, { "Group": 2, "Groupheader": "", "Leftimg": "", "Left": "", "Min": "设备日检", "Right": "", "Rightimg": "" }, { "Group": 2, "Groupheader": "", "Leftimg": "", "Left": "", "Min": "设备周检", "Right": "", "Rightimg": "" }, { "Group": 2, "Groupheader": "", "Leftimg": "", "Left": "", "Min": "设备月检", "Right": "", "Rightimg": "" } ] } ]
以上这篇js根据json数据中的某一个属性来给数据分组的方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。
