Javascript 为什么只记录我的json数据的一部分？

我试图最终在标签中显示json数据。但是，当I console.log记录json数据时，只显示最后两个对象。将数据传递到标签时，仅显示最后一个对象。提前感谢您的帮助

这是我的密码：

var json = 
    {
        "Question:": " What is my name? ",
        "Answer:": " James ",
        "Question:": " What is my age? ",
        "Answer:": " 31 "

    };

for (var key in json)
{
    if (json.hasOwnProperty(key))
    {
        console.log(key + " = " + json[key]);

    }

}
var label = Ti.UI.createLabel({
    text: key + json[key]
});



win3.add(label);

你的问题与钛无关。在JavaScript字典中，不能有两个具有不同值的相同键。为了证明你犯了什么错误，我将重写你的第一行：

var json = {};
json["Question:"] = " What is my name? ";
json["Answer:"] = " James ";
// We are fine untill now.
json["Question:"] = " What is my age? ";
json["Answer:"] = " 31 ";
// Here you overwrote values for keys "Question:" and "Answer:" which were set above.

为了解决您的问题，我将您的json字典更改为字典数组：

var i, key, label;
var json = [
    {
        "Question:": " What is my name? ",
        "Answer:": " James ",
    },
    {
        "Question:": " What is my age? ",
        "Answer:": " 31 "
    }
];

for (i in json) {
    for (key in json[i]) {
        label = Ti.UI.createLabel({
            text: key + json[i][key]
        });
        win3.add(label);
    }
}

您的json对象密钥重复，javascript不会对此抱怨，它只会用第二个值覆盖第一个键值

我明白了，谢谢！我花了很多时间想知道发生了什么事。我可能需要javascript来制作傻瓜lol。
