Question

JSON and Outside.In Radar

Asked by: webseth

I have no clue how to use Javascript/Ajax more than just simple functions. All I'm hoping to accomplish is putting a little code snippet on my site that pulls the Outside.In Radar in JSON format so that visitors can see what's going on around the Lat/Long sent in the request like so:

http://api.outside.in/radar.json?lat=<?=$LATITUDE?>&lng=<?=$LONGITUDE?>    <- From PHP, obviously.

All help  is greatly appreciated! Links, code, anything that can help is great!

Any chance on using the jQuery library in your page? It would greatly simplify the implementation for you.

essentially you would do the following:

$(function() {
      $.getJSON("http://api.outside.in/radar.json?lat=<?=$LATITUDE?>&lng=<?=$LONGITUDE?>", function(data) {
            // handle the response here.
      });
});

That would, on page load, call the API and get the JSON object. After it is loaded, the body of the function (where it says //handle the response here.) would be executed.

Yes. I have the jquery library installed....

 

by: websethPosted on 2009-05-05 at 21:02:36ID: 24311213

I've put in the code above...how do I handle it from there?

 

by: alien109Posted on 2009-05-05 at 22:56:25ID: 24311530

looks like their api isn't set up for jsonp, so no remote calls from javascript. however, you can suck in the json in php and output it to a javascript variable. below is a simple example

<script type="text/javascript">
var stories = <?=file_get_contents('http://api.outside.in/radar.json?lat=40.755970&lng=-73.986702');?>;
$(function() {
      $.each(stories, function() {
            $("#stories").append("<h1>" + this.title + "</h1>" + "<p>" + this.body + "</p>");
      });
});
</script>

You'll need to substitue back in your parameters for latitude and longitude. but for testing - it was the easiest to demonstrate.

I'm all for whichever format works the best. Whichever would be the easiest to implement is OK with me, PHP or Javascript,. I put in the code above, but I'm not getting any output. Checking the source, the file contents are coming through, but no stories are showing up on the page. Am I doing something wrong? I'm clueless with Javascript!

Thanks for all your help.

Strange! Oddly, I couldn't get it to work in the page I was putting it on, but created a new page and it worked flawlessly. There must be some issue with the other JS on the page.

Anyway, your solution worked! Thanks!
