Get property from JSON object?

This probably sounds like a stupid title to this question, but I have a variable that contains a url which gets your location: http://ip-api.com/json Not always accurate, but that of course depends on the user, not the api itself. Now, I ripped out the location finder from part of another api, and I wish to include this in it instead. Essentially: firstHalfofApiMentionedAbove + location(the one I included a link to) + secondHalfOfApiMentionedAbove. But this obviously just sticks the url into the api, and I need to just stick the property keys I want into the api, not the full url. The properties I wish to include are, for example, 'city' and 'region'. Thanks a ton in advance!

Terribly sorry, my esc key broke so I don't know how to use the markup sheet without it. I'll just post it and if you can't read it that well I'll try to find another way.

var location = 'http://ip-api.com/json';

$.getJSON(apiHalf1 + location + tempM + apiHalf2).done(function(data) { $('.current-weather').html(Math.ceil(data['main']['temp']) + '°').css({ 'font-size': '4em', 'color': '#3f3f3f' }); });

--- see how I'm passing in the location as an entire url? That's what I can't have, it needs to just be specific object properties from the JSON.

You need to make an AJAX request to the first API, 'http://ip-api.com/json', to get the data from that server, and when you get the response, your callback will fire, which should contain a second AJAX request to the other API. I'm putting in the 'city' and 'region' properties with a comma between them in this example.

I decided to call the two arguments for the callbacks data1 and data2 so it's clear that they're different. Also, FYI, you can access the 'main' and 'temp' properties with dot notation ("data2.main.temp") as well and it's better to do it this way unless you have to do it the other way.

$.getJSON('http://ip-api.com/json', function(data1) {
  $.getJSON(apiHalf1 + data1.city + ',' + data1.region + tempM + apiHalf2, function(data2) {
    $('.current-weather').html(Math.ceil(data2['main']['temp']) + '°').css({
        'font-size': '4em',
        'color': '#3f3f3f'
    });
  });
});
