Question

我的代码是

    var data = JSON.parse(http.responseText);
        var weatherData = new Weather(cityName, data);
        weatherData.temperature = data.main.temp;
        updateWeather(weatherData);

    function Weather(cityName, data) {
    this.cityName = cityName
    data.weather[0].description = descriptions;
    this._temperature = '';
}

    function updateWeather(weatherData) {
    weatherCity.textContent = weatherData.cityName;
    weatherDescription.textContent = weatherData.descriptions;
    weatherTemperature.textContent = weatherData.temperature;

    loadingText.style.display = 'none';
    weather.style.display = 'block';
}

我得到错误描述没有定义。如果我这样做，工作正常

var data = JSON.parse(http.responseText);
        var weatherData = new Weather(cityName, data.weather[0].description);
        weatherData.temperature = data.main.temp;
        updateWeather(weatherData);

    function Weather(cityName, description) {
    this.cityName = cityName
    this.description = descriptions;
    this._temperature = '';
}

    function updateWeather(weatherData) {
    weatherCity.textContent = weatherData.cityName;
    weatherDescription.textContent = weatherData.descriptions;
    weatherTemperature.textContent = weatherData.temperature;

    loadingText.style.display = 'none';
    weather.style.display = 'block';
}

我不知道现在该做什么。我没有收到价值吗？有人可以解决它，所以我可以理解。我是新手，所以这可能是一个愚蠢的问题。试图以第一种方式做到这一点，因为我想要添加更多东西，如天气压力，风速，日出等。

Answer 1

下面的代码块中有拼写错误 -

function Weather(cityName, description) {
this.cityName = cityName
this.description = descriptions;
this._temperature = '';

请更正this.description = descriptions至this.description = description

Answer 2

这里

mvn spring-boot:run

你写了function Weather(cityName, description) { this.cityName = cityName this.description = descriptions; // <-- this._temperature = ''; }而不是descriptions

描述没有定义
