Question

我正在运行查询并使用表示特定组中人数的值返回JSON。我的数据回复如下：

0: Object 
  count: 10
  grp: 1
1: Object 
  count: 20
  grp: 2
2: Object 
  count: 30
  grp: 3
3: Object 
  count: 40
  grp: 4

我想得到的是运行总数并保存在一个数组中，所以我最终会得到这样的结果：

[[0,10],[1,30],[2,60],[3,100]]

这是我的开始，但不确定我需要在push中添加什么。

d1_1 = [];
$.each(data.rows, function(index, value){
d1_1.push(***what goes here?***);
});

Answer 1

这可以解决这个问题吗？

var input = [{count:10, grp:1},{count:20,grp:2},{count:30,grp:3},{count:40,grp:4}];
counter = 0;
var d1_1 = [];
jQuery.each(input, function(index, elem) {
counter += elem.count;
d1_1.push([index,counter]);
});

var json = [{count: 10, group: 1},{count: 20, group: 2}, {count: 30, group: 3},{count: 40, group: 4}];
var myJSONArray = [];
var myArray = [];

$.each(json, function(index, value){    
    //Results in [{count: 10, group: 1}, {count: 20, group: 2}, etc]
    var temp = {"count": value.count, "group": value.group};
    myJSONArray.push(temp);
    //console.log(myJSONArray);

    //Results in [10, 1], [20, 2], etc
    myArray.push([value.count, value.group]);
    //console.log(myArray);
});

如果你想将索引推入你的数组，你可以像这样做

var json = [{count: 10, group: 1},{count: 20, group: 2}, {count: 30, group: 3},{count: 40, group: 4}];
var myArray = [];

$.each(json, function(index, value){    
    //Results in [0, 10], [1, 20], etc
    myArray.push([index, value.count]);
    //console.log(myArray);
});

Answer 3

var json = [{count: 10,grp: 1}, {count: 11,grp: 2}],
        result = [],
        temp = [];

    for (var i in json) {
        temp.push(json[i].grp, json[i].count);
        result.push(temp);
        temp = [];
    }

从返回的JSON获取总运行/百分比
