使用Javascript / jQuery基于值动态拆分数组
我正在尝试根据JSON对象中内部数组的值动态分割数组。
假设我从OpenWeatherAPI收到所述数据：
var data = [
{
id: "1",
date: "2017-11-27",
type: "Meeting",
log_in: "06:30:00",
log_out: "11:50:00"
},
{
id: "1",
date: "2017-11-27",
type: "Lunch",
log_in: "12:00:00",
log_out: "01:00:00"
},
{
id: "1",
date: "2017-11-27",
type: "Seminar",
log_in: "1:15:00",
log_out: "03:05:00",
},
{
id: "2",
date: "2017-11-28",
type: "Lunch",
log_in: "12:00:00",
log_out: "01:00:00"
},
{
id: "2",
date: "2017-12-28",
type: "Out of the Office",
log_in: "03:00:00",
log_out: "05:00:00"
}
];
var newObj = {};
for (var i = 0; i < data.length; ++i) {
//if a obj for this id does not exist yet, create
if (newObj[data[i].id] == undefined)
{
newObj[data[i].id] = {"id": data[i].id, "date": data[i].date, "logs": []};
}
//store log into logs array using obj id
newObj[data[i].id].logs.push({"type" : data[i].type, "log_in" : data[i].log_in, "log_out" : data[i].log_out});
}
console.log(newObj); JSONObject jsonObject = new JSONObject(Your_Sring_data);
String id= jsonObject.getJsonString("id");
String firstName= jsonObject.getJsonString("firstName");
String lastName= jsonObject.getJsonString("lastName");
String fullName= jsonObject.getJsonString("fullName");
如何根据 var jsonData={

这几乎是我手动将日期转换为YYYY-MM-DD格式，但我仍然在努力根据我得到的结果制作动态数组：
结果：
编辑＃1 ：
我正在寻找的最终结果应该是这样的：
list2 个答案:
答案 0 :(得分：0)
我完全不明白这个问题，但这就是你要找的东西：
var arr=[];
var list = jsonData['list'];
list.filter(function(item) {
var temp = item.dt_txt.split(" ")[0];
arr.push({[temp]: item});
});
答案 1 :(得分：0)
我无法创建动态变量名称;除此之外，这段代码确实处理了其他方面;
