js数组工具处理之合并相同字段分组

话不多说直接上码：

以下是根据time进行分组的

var tempList = [{ userImage: '', userName: '李测试', userWork: '前端', iPhone: '18516776220', time: '2017-11-17',company:"上海测试一公司"},{ userImage: '', userName: '刘测试', userWork: '前端', iPhone: '18511111111', time: '2017-11-18', company: "上海测试二公司"},{ userImage: '', userName: '黄一明', userWork: '前端', iPhone: '18588888888', time: '2017-11-18', company: "上海测试三公司"},{ userImage: '', userName: '黄大明', userWork: '前端', iPhone: '18588888888', time: '2017-11-18', company: "上海测试五公司" },{ userImage: '', userName: '董测试', userWork: '法制特', iPhone: '18522222222', time: '2017-11-20', company: "上海测试二公司"}];var map = {},dest = [];for (var i = 0; i < tempList.length; i++) {var ai = tempList[i];if (!map[ai.time]) {dest.push({initial: ai.time,busInfoList: [ai]});map[ai.time] = ai;} else {for (var j = 0; j < dest.length; j++) {var dj = dest[j];if (dj.initial == ai.time) {dj.busInfoList.push(ai);break;}}}}console.log(dest);
