Lewisham Air Quality measurement from King's College API

Air Quality

var sitecode = "LW4"
var URL =  "http://api.erg.kcl.ac.uk/AirQuality/Daily/MonitoringIndex/Latest/SiteCode=" + sitecode + "/Json";


console.log('Fetching air quality data from-' + URL);


  function processResult(data) {
    var LAsite_data = data.DailyAirQualityIndex.LocalAuthority;
    console.log(data);
    console.log(LAsite_data.Site['@SiteName']);
    console.log(LAsite_data.Site.Species[0]['@AirQualityBand']); 
    }

  $.getJSON(url, processResult);

Think you had a type on line 12 Species - instead of species :-)

var sitecode = "LW4"
var URL =  "http://api.erg.kcl.ac.uk/AirQuality/Daily/MonitoringIndex/Latest/SiteCode=" + sitecode + "/Json";


console.log('Fetching air quality data from-' + URL);


  function processResult(data) {
    var LAsite_data = data.DailyAirQualityIndex.LocalAuthority;
    console.log(data);
    console.log(LAsite_data.Site['@SiteName']);
    console.log(LAsite_data.Site.Species[0]['@AirQualityBand']); //path was given in Json

    }

  $.getJSON(url, processResult);

Try this instead

`var sitecode = "LW4"
var URL = "http://api.erg.kcl.ac.uk/AirQuality/Daily/MonitoringIndex/Latest/SiteCode=" + sitecode + "/Json";
$.ajax({
url: URL,
type: "GET",
crossDomain: true,
dataType: "json",
success: function(response) {
console.log(response);
processResult(response);
},
error: function(xhr, status) {
alert("error");
}
});

function processResult(data) {
var LAsite_data = data.DailyAirQualityIndex.LocalAuthority;
console.log(LAsite_data.Site['@Sitename']);
console.log(LAsite_data.Site.Species[0]['@AirQualityBand']); //path was given in Json

}`
