我正在建立一个天气网站,我使用Wunderground的API。在AJAX XML转储中,"icon"的值似乎是可行的。此响应将动态更改页面上的CSS。我有多个状态的页面,我想可能的,但我似乎不能让他们工作。它似乎在第一个"if"语句后停止。我需要它来检查是否wu_icon ==某些条件,如果不是,移动到下一个,看看是否wu_icon ==下一组条件。

任何帮助都将非常感激。

function get_weather(position) {
    var latitude = position.coords.latitude;
    var longitude = position.coords.longitude;
    wu_query = latitude + ',' + longitude;
    //Weather underground request URL format.
    wu_url = wu_base_url + '/' + wu_api_key + '/' + wu_features + '/q/' + wu_query + '.json';
    console.log('URL Query: ' + wu_url);

        }

你的if语句应该像

if (wu_icon == 'partlycloudy' || wu_icon == 'partlysunny' || wu_icon == 'unkown')

的缩写形式是

if (["partlycloudy","partlysunny","unkown"].indexOf(wu_icon) != -1)
