    }
}

Getting JSON Data stored on external sites

you need to wrap the json data in a function

dataHandler({
	"full_name" : "Ray Villalobos",
	"title" : "Staff Author",
	"links" : [
			{ "blog"     : "http://iviewsource.com" },
			{ "facebook" : "http://facebook.com/iviewsource" },
			{ "podcast"  : "http://feeds.feedburner.com/authoredcontent" },
			{ "twitter"  : "http://twitter.com/planetoftheweb" },
			{ "youtube"  : "http://www.youtube.com/planetoftheweb" }
		]
});

Script file

function dataHandler(info) {
	var output='';
	for (var i = 0; i <= info.links.length-1; i++) {
		for (key in info.links[i]) {
			if (info.links[i].hasOwnProperty(key)) {
				output += '<li>' + 
				'<a href = "' + info.links[i][key] +
				'">' + key + '</a>';
				'</li>';
	    }   
		}
	}

	var update = document.getElementById('links');
	update.innerHTML = output;

}

HTML

Load the Json file after the script file

<script src="myscript.js"></script>
<script src="http://iviewsource.com/exercises/json/data.json"></script>
