Question

我试图调用json api并迭代结果，但得到错误

未捕获的TypeError：无法在＆＃39;中使用＆＃39;运营商搜索＆＃39; 379741＆＃39;在 {＆＃34;状态＆＃34;：真，＆＃34;航班＆＃34; ...}

    (function () {
        var flickerAPI = 'http://whateverorigin.org/get?url=' + 'http://www.dubaiairports.ae/FIDS_cache/arrivals_today_all.json' + '&callback=?';
        $.getJSON(flickerAPI, {
            format: "json"
        })
          .done(function (data) {

              //$.each(data.contents, function (flights) {
              //    alert(flights.flightnumber);
              //});

          });
    })();

在这里摆弄http://jsfiddle.net/au8ahmho/1/

我希望这可以帮到你！

(function () {
            var flickerAPI = 'http://whateverorigin.org/get?url=' + 'http://www.dubaiairports.ae/FIDS_cache/arrivals_today_all.json' + '&callback=?';
            $.getJSON(flickerAPI, {
                format: "json" ,
                beforeSend : function(){
                  $('#el').html(' waiting a response from http://whateverorigin.org/');
                }
            })
            .done(function (data) {
                console.log(JSON.parse(data.contents) );
                var ff = JSON.parse(data.contents) ;
                var numbers = ff.flights.map(function(flight){
                    return flight.flightNumber;
                });
                $('#el').html( numbers.join('<br>') );
               

            });
        })();

这取决于返回的JSON的布局方式。根据您发布的错误，您似乎应该尝试flights.flight[flightnumber]。
