我有一个以奇怪方式输出的天气插件

如何解决我有一个以奇怪方式输出的天气插件

像这样：https://ghostbin.co/paste/ohsuar

我只需要当前的温度值。我如何获得它？

假设“weatherObject”是对象的变量。我已经尝试过“weatherObject.current.temperature”并且它输出“undefined”。

[
  {
    "location": {
      "name": "New York,NY","lat": "40.713","long": "-74.007","timezone": "-4","alert": "","degreetype": "C","imagerelativeurl": "http://blob.weather.microsoft.com/static/weather4/en-us/"
    },"current": {
      "temperature": "14","skycode": "27","skytext": "Cloudy","date": "2021-05-02","observationtime": "03:00:00","observationpoint": "New York,"feelslike": "15","humidity": "40","winddisplay": "16 km/h Southwest","day": "Sunday","shortday": "Sun","windspeed": "16 km/h","imageUrl": "http://blob.weather.microsoft.com/static/weather4/en-us/law/27.gif"
    },...
  }
]

解决方法

您的 weatherObject 数组中有许多对象。所以你必须用你想要获取的数组元素的索引来调用它。此外，嵌套对象的键是字符串，因此您不能使用点符号来调用它。您必须使用方括号。

对于数组的第一个元素，它将是：

weatherObject[0]["current"]["temperature"]

工作示例：

var weatherObject = [
  {
    "current": {
      "temperature": "14"
    }
  }
];

console.log(weatherObject[0]["current"]["temperature"]);
