Hi! I have build a weather app with jQuery, and everthing works nice. The url is https://api.forecast.io/forecast/ with a couple of parameters after that. I have created a bunch of variables to store the data. Finally in the end I do like this:

1.   var forecastData = function () {
       $.getJSON(url, callback);
      };
    
     $(document).ready(function() {
      forecastData();

     });

My question now if there's some easy way to handle errors, like if not null (if a param like longitude is missing), success/error - but to keep what I have coded so far? Have tried a bunch of thing but it wont work.

Thanks!
