我有以下JSON数据： {成功：欢迎你} 我已将其命名为 json 在我的JavaScript代码中。

I have the following JSON data: {"success":"You are welcome"} that I have named json in my JavaScript code.

当我想提醒欢迎你我做 json.success 。所以现在我面临的问题是，如果我想提醒成功，那该怎么办？有没有办法得到它？

When I want to alert You are welcome I do json.success. So now the problem I am facing is that, what about if I want to alert success. Is there any way to get it?

如果您的对象是

var obj = {"success":"You are welcome"};

您可以获得密钥数组

var keys = Object.keys(obj);

然后将其打印为

console.log( keys[ 0 ] ); //or console.log( keys.join(",") )

var obj = {"success":"You are welcome"};
var keys = Object.keys(obj);
console.log(keys[0]);
