Question

这个json对象是通过ajax返回的。

[{"fiscal_year":2.012,"groupName":"Group1","Quantity":31666,"Revenue":"18,700,482.83"},
{"fiscal_year":2.013,"groupName":"Group1","Quantity":9264,"Revenue":"8003393.585"},
{"fiscal_year":2.014,"groupName":"Group1","Quantity":2483,"Revenue":"3,413,629.16"},
{"fiscal_year":2.012,"groupName":"Group2","Quantity":0,"Revenue":"3,055,922.45"},
{"fiscal_year":2.013,"groupName":"Group2","Quantity":0.00E+00,"Revenue":"3,916,824.84"},
{"fiscal_year":2.014,"groupName":"Group2","Quantity":0,"Revenue":"3,444,182.80"}
]

我需要修改它并将其保存为另一个json对象，以便我可以在列中显示年份。

 $.ajax({
  url: 'static/doc/sample.json',
  type: 'GET',
  dataType: 'JSON',
  success: function(data){
    var obj = [];
    var business_group_nm = '';
    $.each(data,function(key,value){

      if(business_group_nm!=value.groupName){
        obj.push({
          "groupName": value.groupName,
          "year":[value.fiscal_year:{
               "Quantity":value.Quantity,
               "Revenue":value.Revenue
          }];
        });

      }else{
        obj["year"].push(value.fiscal_year:{
               "Quantity":value.Quantity,
               "Revenue":value.Revenue
          }];
        });

      }
      business_group_nm = value.business_group_nm;
    });

最终的json对象我希望它是：

[
    {
        "business_group_nm": "Group1",
        "year": [
            {
                "2012": {
                    "Quantity": "31666",
                    "Revenue": "18,700,482.83"
                }
            },
            {
                "2013": {
                    "Quantity": "31666",
                    "Revenue": "18,700,482.83"
                }
            }
        ]
    },
    {
        "business_group_nm": "Group2",
        "year": [
            {
                "2012": {
                    "Quantity": "31666",
                    "Revenue": "18,700,482.83"
                }
            },
            {
                "2013": {
                    "Quantity": "31666",
                    "Revenue": "18,700,482.83"
                }
            }
        ]
    },
];

但是我收到错误'Uncaught SyntaxError：Unexpected token：'

"year":[value.fiscal_year:{
              "Quantity":value.Quantity,
              "Revenue":value.Revenue
}];

由于

Answer 1

obj["year"].push(value.fiscal_year:{
       "Quantity":value.Quantity,
       "Revenue":value.Revenue
  }];
});

这没有任何意义，你不能在实际的对象表示法“外部”使用那种语法。使用.push在这里也是错误的，这是一种Array方法，而不是对象。

以下行中的某些内容应该可以将新属性添加到obj["year"]，使用fiscal_year值作为属性名称并将其指定为值：

obj["year"][value.fiscal_year] = {
  "Quantity":value.Quantity,
  "Revenue":value.Revenue
};

编辑：在这个地方，

"year":[value.fiscal_year:{
  "Quantity":value.Quantity,
  "Revenue":value.Revenue
}];

您使用的是方括号，表示数组，而不是对象 - 但数组没有任何此类“关联”键。如果你想将它作为一个对象，那么也可以在这里使用花括号。

从ajax返回的Json对象创建一个Json对象
