What is the best way to compare a JSON object and a string in JavaScript?

Currently, I am working on developing the website layout for . Most of the data retrieval and display have been successful so far.

However, when attempting to filter my search results to show only stop names associated with Subways, I encountered some errors. You can find the JSON page related to this issue at . Specifically, when trying to access stops with the route name 'Yonge-University-Spadina Subway', I received an error message stating '

Uncaught TypeError: Cannot call method 'equals' of undefined
'. I also attempted using the '===' operator without success. Despite searching extensively online for a solution, I have not been able to resolve this issue. As a beginner in JavaScript, it is possible that I overlooked something crucial in my code. Here is the portion of my code causing the problem:

 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html>
    <head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
    <script src="http://code.jquery.com/jquery-latest.js"></script>
    <script>
      $(document).ready(function(){
        // retrieving the data.
        $.getJSON("http://myttc.ca/finch_station.json?callback=?", function(data){
          //Storing the string in variable.   
          var subway="Yonge-University-Spadina Subway";

          console.log(data);
          //Displaying the station name first in a div called "stations" in the body.
          $("#stations").append('Station: ' + data.name + '<br/>');

          //Iterating through the stops array to display each stop name 
          $.each(data.stops, function(i,stopz){

          $("#stations").append('&nbsp;&nbsp;Stop: ' + stopz.name + '<br/>');
          //This is my problem area.Not able to compare the routes.name to the string.   
          if(stopz.routes.name === subway) {
            $.each(stopz.routes, function(i,routez) {
              //Displaying the Departure time and shape of the stops.
              $.each(routez.stop_times, function(i,timez) {
                $("#stations").append('&nbsp;&nbsp;&nbsp;&nbsp;Departure-time: ' + timez.departure_time + ' || Shape: ' + timez.shape + '<br/>');  
              });
            });
            }
          });
         });
       });
     </script>

 </head>
 <body>

 <div id="stations">
 </div>
 </body>
 </html>

I would greatly appreciate any assistance provided. Thank you.

Answer №1

After reviewing the structure of your stops data:

{"routes":[],"name":"Finch Station GO Hallway","uri":"finch_station_go_hallway","agency":"Toronto Transit Commission"}

Your reference to stopz.routes.name appears to be incorrect. It seems you intended to refer to stopz.name. Therefore, your code should be adjusted as follows:

            if(stopz.name === subway)
            {
                $.each(stopz.routes, function(i,routez){
                    // ... etc ...
                });
            }
