Encountered a JavaScript error while parsing the HTTP response

Currently, I am faced with the challenge of extracting and processing data from the www.skiddle.com API using Javascript:

$.ajax({
        url: 'http://www.skiddle.com/api/v1/events/search/?api_key=myapikey' + '&latitude=' + lat + '&longitude=' + long + '&radius=800&eventcode=LIVE&order=distance&description=1',
        type: "GET",
        success: function(response) {
        var list = [];
        $(response).find("results").each(function() {
        var el = $(this);
        var obj = {
                   "eventname": el.find("eventname").text(),
                   "imageurl" : el.find("imageurl").text(),
                  };
        list.push(obj);
        });

Upon examining the response, it appears to contain a results property with a single element within an array:

{error: 0, totalcount: "1", pagecount: 1, results: Array(1)}

However, despite this structure, when attempting to parse it using $(response).find("results"), no output is returned.

Answer №1

If you're confident that your response will include a property called result array, you can use response.results to access the array.

success: function(response) {

  $.each(response.results,function(indx,item){
       console.log(item);
       var obj = {  
                    eventname: item.eventname,
                    imageurl : item.imageurl
                 };
      list.push(obj);
  });

}

Assuming list has been defined as an array earlier.

If you know there is only one item in the array, you don't need a loop – you can simply access it using response.results[0]

success: function(response) {
  if (response.results.length>0) {
     var obj = { eventName: response.results[0].eventname,
                 imageurl : response.results[0].imageurl };
     list.push(obj);
  }
}

I've also observed that your new object has the same property names as the object being iterated through. In such cases, you can directly add the same object

 list.push(response.results[0]);

This will add the first item as it is. Any additional properties in the item will also be included in the added item in the list.

Instead of trying to parse the response as XML, make sure you are treating it properly as JSON.

To retrieve the desired list, simply include the following code snippet:

success: function(response) {
    var list = (response.results || []).map(function(result) {
        return {  
            eventname: result.eventname,
            imageurl : result.imageurl
        };
    });
}
