Javascript error parsing http response

I am trying to parse the response from the www.skiddle.com API in 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);
});


The response actually has a
results
property with one element in the array:

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


but I can't seem to parse it correctly,
$(response).find("results")
returns nothing.

If you are sure that there will be a result array property in your response, you may simply use response.results which gives you 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 is an array defined earlier.

Also if you are sure there will be only one item in the array, you do not need a loop, you can access it via 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 also noticed that the your new object has the same property names as the object you are iterating. In that case, you can simply add the same object

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

Of course this will add the first item as it is , which means if that has additional properties (other than eventname and imageurl) those will be present in the item you are adding to list now..
