Question

我有一个json响应，我想从中创建新的json对象

response = [
         {Detail:"Reuters ID",keyName:"Reuters_ID"},
         {Detail:"Parity One",keyName:"parity_one"},
         {Detail:"Parity level",keyName:"parity_level"}
        ];

我想在操作键和值对

之后实现这一点

lang_Arr =[
      {Reuters_ID:"Reuters ID"},
      {parity_one:"Parity One"},
      {parity_level:"Parity level"}
     ];

我尝试过两种方式 1）在这个获得错误中意外的tokken（。）

    var Lang_arr =[];
    angular.forEach(response, function(value, key) { 
     Lang_arr.push({value.keyName:value.Detail});

    });

2）这里获得了不可预见的令牌[

 var Lang_arr =[];
    angular.forEach(response, function(value, key) { 
     Lang_arr.push({value['keyName']:value['Detail']});

    });

我已经尝试过分配价值，但它也没有在那里工作

    var Lang_arr=[];
        var k ='';
        var v ='';
        var i = 1;

    angular.forEach(response, function(value, key) { 
        k ='';
        v ='';
        i = 1;
        angular.forEach(value,function(val,key){
            if(i == 1 )
                k = val;
            if(i == 2)
                v = val;

            if(!empty(k) && !empty(v))
                Lang_arr.push({k:v})



            i++;
        }); 

    });

Answer 1

您可以使用javascript map函数将对象映射到数组

var response = [
         {Detail:"Reuters ID",keyName:"Reuters_ID"},
         {Detail:"Parity One",keyName:"parity_one"},
         {Detail:"Parity level",keyName:"parity_level"}
];
        
var lang_Arr =[];

lang_Arr = response.map(function(o){
  var obj = {};
  obj[o.Detail] = o.keyName;
  return obj;
  
})

console.log(lang_Arr)

使用Angular forEach ，您也可以实现此功能

var response = [
         {Detail:"Reuters ID",keyName:"Reuters_ID"},
         {Detail:"Parity One",keyName:"parity_one"},
         {Detail:"Parity level",keyName:"parity_level"}
        ];
        var modifiedArray = [];
      angular.forEach(response, function(val, key) {
        var res = {};
            res[val.keyName] = val.Detail;
        this.push(res);
        }, modifiedArray);  

console.log(modifiedArray)

您必须在获得响应的http调用中分配

$htpp.get(....).then(function(response){
lang_arr = []; 
 response.forEach(function(obj){
    var item = {obj.keyName : obj.detail};
    lang_arr.push(item);
}

在角js中使一个（键值对）的值成为另一个的键
