在将 JSON 数组编码为 JSON 后如何编辑它？

我想编辑以下 JSON 数组：

{"Status":"OK","Message":"API Call worked","Result":[{"interval":"2014-11-30",
"leads":0,"name":"CarEnquiry","status":"NEW","appointment":0},
{"interval":"2014-11-30","leads":0,"name":"CarEnquiry","status":"CALL1","appointment":0},
{"interval":"2014-11-30","leads":0,"name":"CarEnquiry","status":"CALL2","appointment":0}]}

改成这个

{"Result":"OK","Records":[{"interval":"2014-11-30",
"leads":0,"name":"CarEnquiry","status":"NEW","appointment":0},
{"interval":"2014-11-30","leads":0,"name":"CarEnquiry","status":"CALL1","appointment":0},
{"interval":"2014-11-30","leads":0,"name":"CarEnquiry","status":"CALL2","appointment":0}]}

如何在 Javascript 中编辑数组？

【问题讨论】：

请问您为什么需要这样做；为什么在生成原始数组时无法执行此操作；以及这个 JSON 是如何生成的？
描述有什么区别。
也许仅仅 3000 万次关于操作 javascript 对象的培训会有所帮助（这很容易）。
@KavehRassoulzadegan - 我用谷歌搜索，找不到任何相关内容。
@JamesDonnelly - 数组的编码由一个为所有 JSON 对象生成相同格式的整体 API 控制器完成 - 即 "Status":"OK","Message":"API Call worked","Result":[。我正在使用一个第三方库，它期望起始行是{"Result":"OK","Records":[。所以只是做一个解决方法。

如果你真的想用 JavaScript 来做这件事，你可以简单地创建一个新的 JavaScript 对象（我在下面称之为newJSON），然后手动将它的属性分配为你的属性当前的 JSON（我称之为 oldJSON）：

var oldJSON = ...,
    newJSON = {};

newJSON.Result = oldJSON.Status;
newJSON.Records = oldJSON.Result;

newJSON 现在是您想要的格式的 JavaScript 对象。如果我们为此调用JSON.stringify，我们会看到结果。在下面的 sn-p 上单击 Run code sn-p 以将字符串化结果提醒您。

var oldJSON = {"Status":"OK","Message":"API Call worked","Result":[{"interval":"2014-11-30","leads":0,"name":"CarEnquiry","status":"NEW","appointment":0},{"interval":"2014-11-30","leads":0,"name":"CarEnquiry","status":"CALL1","appointment":0},{"interval":"2014-11-30","leads":0,"name":"CarEnquiry","status":"CALL2","appointment":0}]},
    newJSON = {};

newJSON.Result = oldJSON.Status;
newJSON.Records = oldJSON.Result;

alert(JSON.stringify(newJSON));

完美——正是我所需要的！谢谢

【解决方案2】：

x['Records']=x.Result;
x['Result']=x.Status;

如果您不介意 json 中的一些额外键，那么您不需要删除它们，否则如果您想删除它们，请检查这些问题 here。希望对您有所帮助。

【解决方案3】：

也许您可以尝试修改和/或删除 json 键。

我会这样做：

var json = '
    {"Status":"OK",
     "Message":"API Call worked",
     "Result": [
        {"interval":"2014-11-30", "leads":0,"name":"CarEnquiry","status":"NEW","appointment":0},
        {"interval":"2014-11-30", "leads":0,"name":"CarEnquiry","status":"CALL1","appointment":0},
        {"interval":"2014-11-30", "leads":0,"name":"CarEnquiry","status":"CALL2","appointment":0}]}
';

var obj = JSON.parse(json);

obj.Records = obj.Result;
delete obj.Result;

obj.Result = obj.Status;
delete obj.Status;

delete obj.Message;

json = JSON.stringify([obj]);

您将获得：

{"Records": [
     {"interval":"2014-11-30", "leads":0,"name":"CarEnquiry","status":"NEW","appointment":0},
     {"interval":"2014-11-30", "leads":0,"name":"CarEnquiry","status":"CALL1","appointment":0},
     {"interval":"2014-11-30", "leads":0,"name":"CarEnquiry","status":"CALL2","appointment":0}
   ],
 "Result":"OK"
}
