Ajax call is not fetching the data

Question

$(document).ready(function(){

  /* Union Station */
  $.getJSON("http://myttc.ca/Union_station.json?callback=?",
       function(data){
         if (routes.length > 0) {

            $.each(data.stops, function(i,item){
               $("#Union").append("<p>Stop Name: " + item.name + "</p>");
               $.each(item.routes, function(i,item){
                  $.each(item.stop_times, function(i,item){
                     $("#Union").append("<p>Departure Times: " + item.departure_time + "</p>");
                     $("#Union").append("<p>Shape: " + item.shape + "</p>");
                  });
               });
            });
        }
   });

});     

I am getting an empty screen in this
can anyone help to fix this jquery to fetch data from json I only want to display the stop details with departure times

Answer 1

It should be:

function(data){
    if (data.stops.length > 0) {

Here's the result of the ajax:

Object {time: 1367157909, stops: Array[8], name: "Union Station", uri: "union_station"}

EDIT:

I guess you need some extra logic then, here's the object:

stops: Array[8]
0: Object
1: Object
2: Object
3: Object
4: Object
5: Object
6: Object
7: Object
  agency: "Toronto Transit Commission"
  name: "Union Station Subway Platform"
  routes: Array[1]
    0: Object
      name: "Yonge-University-Spadina Subway"
      route_group_id: "1"
      stop_times: Array[6]
        0: Object
          departure_time: "10:07a"
          departure_timestamp: 1367158079

So you could do something like:

for (var i = 0, l = data.stop.length, stop; i < l; i++) {
    stop = data.stop[i];

    // If current stop has stop_times then...
    if (stop.stop_times.length) {
        // do something...
        console.log(stop.stop_times);
    }
}

routes is probably not what you're looking for in:

function(data){
    if (routes.length > 0) {

At least I can't see where routes would be set. You probably need

function(data){
    if (data.length > 0) {

There is no routes in the success callbak, so remove that condition

$(document).ready(function(){

    /* Union Station */
    $.getJSON("http://myttc.ca/Union_station.json?callback=?",
              function(data){

                  $.each(data.stops, function(i,item){
                      $("#Union").append("<p>Stop Name: " + item.name + "</p>");
                      $.each(item.routes, function(i,item){
                          $.each(item.stop_times, function(i,item){
                              $("#Union").append("<p>Departure Times: " + item.departure_time + "</p>");
                              $("#Union").append("<p>Shape: " + item.shape + "</p>");
                          });
                      });
                  });
              });

});
