访问并更改2d Json数组，Javascript

我试图访问和更改从JSON API调用收到的数据。访问并更改2d Json数组，Javascript

呼叫的格式是这样的：

{ 
    "count": 391, 
    "value": [ 
    { 
     "id": "id1", 
     "name": "name1", 
     "url": "url1", 
     "project": { 
     "id": "projId", 
     "name": "BT-GIT", 
     "url": "otherurl", 
     "state": "wellFormed" 
     }, 
     "defaultBranch": "master", 
     "remoteUrl": "remote" 
    }, 
    { 
     "id": "id2", 
     "name": "name2", 
     "url": "url2", 
     "project": { 
     "id": "projId", 
     "name": "BT-GIT", 
     "url": "otherurl", 
     "state": "wellFormed" 
     }, 
     "defaultBranch": "master", 
     "remoteUrl": "remote" 
    },...

，我想一个额外的条目添加到每个“值”，这样我有：

 { 
      "id": "id1", 
      "name": "name1", 
      "url": "url1", 
      "project": { 
      "id": "projId", 
      "name": "BT-GIT", 
      "url": "otherurl", 
      "state": "wellFormed" 
      }, 
      "defaultBranch": "master", 
      "remoteUrl": "remote" 
      "date": "date" <--------- 
     }

我试着：

$.each(data, function (idx) { 
       data.value[idx].currentDate = new Date().toJSON().slice(0, 16); 
      })

和：

$.each(data, function (idx) { 
       data[1][idx].currentDate = new Date().toJSON().slice(0, 16); 
      })

任何关于如何解决此问题的想法？

非常感谢。

它看起来像你迭代上'data'，当它听起来像你想迭代'data.value'。 '$ .each（data.value，function ...'可能会诀窍 – neilsimp1

该文档解释了如何使用'$ .each'很清楚地迭代overan对象：http://api.jquery.com/jquery.each /＃jQuery-each-object-callback – user3297291

您可以与您现有的代码做的，但刚需略有调整，

var data = { 
    "count": 391, 
    "value": [{ 
     "id": "id1", 
     "name": "name1", 
     "url": "url1", 
     "project": { 
      "id": "projId", 
      "name": "BT-GIT", 
      "url": "otherurl", 
      "state": "wellFormed" 
     }, 
     "defaultBranch": "master", 
     "remoteUrl": "remote" 
    }, { 
     "id": "id2", 
     "name": "name2", 
     "url": "url2", 
     "project": { 
      "id": "projId", 
      "name": "BT-GIT", 
      "url": "otherurl", 
      "state": "wellFormed" 
     }, 
     "defaultBranch": "master", 
     "remoteUrl": "remote" 
    }] 
}; 

$.each(data.value, function (index,data) { 
       data.currentDate = new Date().toJSON().slice(0, 16); 
      }); 
console.log(data);

data.value = data.value.map(function(v) { v.date = Date.now() })
