访问JSON值持有者的名称

Question

我有以下JSON数据:

{
    "pages": {
        "22989": {
            "title": "Paris",
            "links": [{
                "ns": 0,
                "title": "11th arrondissement of Paris"
            }]
        }
    }
}

如何在"页面"内访问字符串"22989"？(我想要变量的名称,而不是它的值.)

Answer 1

var object = {"pages":{"22989":{"title":"Paris","links":[{"ns":0,"title":"11th arrondissement of Paris"}]}}}

for(key in object.pages) {
    alert(key); // "22989"
}
