Question

我想从以下json API返回值中调用仪表（732）的数据：

{"results":1,"data":[{"wind":{"degrees":200,"speed_kts":6,"speed_mph":7,"speed_mps":3,"speed_kph":11},"temperature":{"celsius":16,"fahrenheit":61},"dewpoint":{"celsius":14,"fahrenheit":57},"humidity":{"percent":88},"barometer":{"hg":30.06,"hpa":1018,"kpa":101.79,"mb":1017.92},"visibility":{"miles":"Greater than 6","miles_float":6.21,"meters":"10,000+","meters_float":10000},"ceiling":{"code":"BKN","text":"Broken","feet":2400,"meters":732,"base_feet_agl":2400,"base_meters_agl":732},"elevation":{"feet":256,"meters":78},"location":{"coordinates":[-2.27495,53.353699],"type":"Point"},"icao":"EGCC","station":{"name":"Manchester Airport"},"observed":"2020-07-18T00:50:00.000Z","raw_text":"EGCC 180050Z AUTO 20006KT 9999 BKN024 16/14 Q1018","flight_category":"MVFR","clouds":[{"code":"BKN","text":"Broken","feet":2400,"meters":732,"base_feet_agl":2400,"base_meters_agl":732}],"conditions":[]}]}

此代码似乎没有调用它：

jQuery.ajax({
  type: 'GET',
  url: 'https://api.checkwx.com/metar/EGCC/decoded',
  headers: { 'X-API-Key': 'apikey' },
  dataType: 'json',
  success: function(data) {
    console.log(data)
    
    var ceiling = data.ceiling.feet;
      
      jQuery('#a53feet').html( ceiling );
    
  }
});

HTML：

<span id="a53feet"></span>

呼叫路径中是否有东西（data.ceiling.feet），这是不对的？

Answer 1

返回的json是您需要使用的数组，如下所示

用于访问英尺数据

data.data [0] .ceiling.feet;

用于访问电表数据

data.data [0] .ceiling.meters

Answer 2

如果您看到console.log，则data是一个对象，该对象具有作为数组的数据，因此要访问您要尝试访问的数据，您需要执行以下操作：

data.data[0].ceiling.meters

如何在Ajax中调用此数据段？
