如何将数据推送到JavaScript对象文本

我想用JavaScript对象文字推送数据。但是，无论如何也找不到。我正在尝试以下代码

var wd = { item: [] }
wd.item = {
    country: weatherData.query.results.weather.rss.channel.location.country,
    state: weatherData.query.results.weather.rss.channel.location.city,
    displayState: weatherData.query.results.weather.rss.channel.location.city + ', ' + weatherData.query.results.weather.rss.channel.location.country,
    data: [
    {
        date: weatherData.query.results.weather.rss.channel.item.forecast[0].date,
        day: weatherData.query.results.weather.rss.channel.item.forecast[0].day,
        high: weatherData.query.results.weather.rss.channel.item.forecast[0].high,
        low: weatherData.query.results.weather.rss.channel.item.forecast[0].low,
        text: weatherData.query.results.weather.rss.channel.item.forecast[0].text
    }
    ]
};

我正在尝试使用push（）函数，但遇到了错误

添加一项后，结果如下

 Object {item: Object}item: Objectcountry: "India"data: Array[1]0: Object$$hashKey: "object:254"date: "4 Jan 2015"day: "Sun"high: "84"low: "66"text: "Partly Cloudy"__proto__: Objectlength: 1__proto__: Array[0]displayState: "Bangalore, India"state: "Bangalore"__proto__: Object__proto__: Object

但是，在此之后，我无法添加新数据。有人能帮忙吗

下面的代码正在运行

var wd = { item: [] };
var
                location = weatherData.query.results.weather.rss.channel.location,
                forecast = weatherData.query.results.weather.rss.channel.item.forecast[0];

            wd.item.push({
                country: location.country,
                state: location.city,
                displayState: location.city + ', ' + location.country,
                data: {
                    date: forecast.date,
                    day: forecast.day,
                    high: forecast.high,
                    low: forecast.low,
                    text: forecast.text
                }
            });
            console.log(wd);

谢谢大家的帮助。

您的第二行代码用一个普通对象覆盖了

wd.item

处的数组。我假设您打算将对象添加到数组中

wd.item.push({
  // your big object
});

正如@MightyPork所说的，如果使用变量来保存目标嵌套对象，代码的可读性将大大提高

var wd = { item: [] };
var loc = weatherData.query.results.weather.rss.channel.location;
var forecast = weatherData.query.results.weather.rss.channel.item.forecast;

wd.item.push({
    country: loc.country,
    state: loc.city,
    displayState: loc.city + ', ' + loc.country,
    data: [
        {
            date: forecast[0].date,
            day:  forecast[0].day,
            high:  forecast[0].high,
            low:  forecast[0].low,
            text:  forecast[0].text
        }
    ]
});

嗯，这与问题不太相关，但是为什么不创建一个临时变量并将

weatherData.query.results.weather.rss.channel.item

存储在其中呢？因为这个问题与JSON完全无关，所以我删除了与问题无关的

JSON

tag.um，但是为什么不创建一个临时变量并将
