无法解析来自远程服务器的javascript中的JSON

Question

我从远程服务器返回以下JSON：

{
    "success": true,
    "questions": [{
        "id": 23,
        "text": "Is Sky Blue?",
        "response_type": "Multiple Choice",
        "created_at": "2014-12-05T06:37:20.947Z",
        "updated_at": "2015-03-04T00:00:56.915Z",
        "campaign_id": 38,
        "no_repeats": true,
        "max_repeat": 0,
        "yes_no": false,
        "type": "axy",
        "priority": 0
    }, {
        "id": 24,
        "text": "What is your current employment status?",
        "response_type": "Multiple Choice",
        "created_at": "2014-12-05T06:38:56.076Z",
        "updated_at": "2015-03-04T00:00:56.903Z",
        "campaign_id": 38,
        "no_repeats": true,
        "max_repeat": 0,
        "yes_no": false,
        "type": "axy",
        "priority": 0
    }]
}

我正在使用此代码从远程URL获取数据：

$.get( url, function( data ){
    alert(data.success); // Works
    alert(data. questions); // Returns Blank
});

data.questions返回空。我尝试eval，但它只返回[object]

我做错了什么？

Answer 1

questions是一个数组。试试

alert(data.questions[0].id)

你应该得到23.如果你这样做，那将为你提供访问其余数据所需的洞察力。
