使用$ .each循环jquery从json对象获取相同键的总和

Question

"data": [{
  "Nic": {
    "2017-09":6473,
    "2017-10":66,
    "2017-11-01":69571
  },
  "Nancy": {
    "2017-09":185,
    "2017-10":194,
    "2017-11":2031
  }
}]

我想要

series: [{
  dateValue: '2017-09',
  data: [6473, 185]
}, {
  dateValue: '2017-10',
  data: [66, 194]
}, {
  dateValue: '2017-11',
  data: [69571, 2031]
}]

Answer 1

您可以使用解决方案

＆＃13;

＆＃13;

var data = [{
  "Nic": {
    "2017-09":6473,
    "2017-10":66,
    "2017-11":69571
  },
  "Nancy": {
    "2017-09":185,
    "2017-10":194,
    "2017-11":2031
  }
}];

var series = [];

var keys = Object.keys(data[0]);
var dates = Object.keys(data[0][keys[0]]);

$.each(dates, function(i){
  var temp = {};
  temp["dateValue"] = dates[i];
  temp["data"] = [];
  $.each(keys, function(j){
    temp["data"].push(data[0][keys[j]][dates[i]]);
  });
  series.push(temp);
});

console.log(series);

希望这会对你有所帮助。

Answer 2

这是解决方案。

我使用underscorejs，我建议您使用它。但是，您可以轻松地将其转换为jQuery。

＆＃13;

＆＃13;

var data = [{
  "Nic": {
    "2017-09":6473,
    "2017-10":66,
    "2017-11":69571
  },
  "Nancy": {
    "2017-09":185,
    "2017-10":194,
    "2017-11":2031
  }
}];
var d = data[0];
var k = Object.keys(d);
var v = [];
_.forEach(k, function(ky){v.push(d[ky])});
var f = [];
_.forEach(v, function(vl){
	var kys = Object.keys(vl);
	_.forEach(kys, function(ky){
		var val =_.findWhere(f, {dateValue: ky});
        if(!val){
           val = {dateValue: ky, data: []};
           f.push(val);
        }
        val.data.push(vl[ky]);
	});
});
document.getElementById("val").innerHTML = JSON.stringify(f);

＆＃13;

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
<div id="val">

</div>
