使用javascript重命名数组中的对象键

问题描述

在我的有角度的应用程序中，我得到如下所示的Json数据.

In my angular application i am getting an Json Data like below.

[{"id":"5","name":"Immidiate"},
{"id":"4","name":"30 days"},
{"id":"3","name":"21 days"},
{"id":"2","name":"14 days"},
{"id":"1","name":"7 days"},
{"id":"6","name":"Custom"}]

我需要类似下面的输出

[{"Name":"5","Data":"Immidiate"},
{"Name":"4","Data":"30 days"},
{"Name":"3","Data":"21 days"},
{"Name":"2","Data":"14 days"},
{"Name":"1","Data":"7 days"},
{"Name":"6","Data":"Custom"}]

这是我的代码

$rootScope.DashboardData["Name"] =  widget.seriesname ;
delete $rootScope.DashboardData[widget.seriesname];
$rootScope.DashboardData["data"] =  widget.dataname ;
delete $rootScope.DashboardData[widget.seriesname];
widget.chartSeries = $rootScope.DashboardData;

widget.seriesname是"id"，widget.dataname是"name".

where widget.seriesname is "id" and widget.dataname is "name".

问题:密钥未更改！

推荐答案

使用map函数:

var array = [{"id":"5","name":"Immidiate"},
{"id":"4","name":"30 days"},
{"id":"3","name":"21 days"},
{"id":"2","name":"14 days"},
{"id":"1","name":"7 days"},
{"id":"6","name":"Custom"}];

var resultArray = array.map(function(elm) {
   return { Name: elm[widget.seriesname], Data: elm[widget.dataname]};
});
