    copied!<p>I have a feeling this is very simple, however, I am having trouble getting this to spit out anything other than <strong>undefined</strong> </p> <p>I would like to be able to grab the JSON object passing in a string to the function. Is this possible with a function like below?</p> <pre><code>var dashboardData= { "Dashboard": { "Total_Downloads":95, "Unique_Downloads":30, "Campaign_Threshold":1000, "Downloads_By_Date":[ {"Downloads":6,"Date":"9/6/2012 12:00:00 AM"}, {"Downloads":2,"Date":"9/7/2012 12:00:00 AM"}, {"Downloads":9,"Date":"9/20/2012 12:00:00 AM"}, {"Downloads":2,"Date":"9/22/2012 12:00:00 AM"}, {"Downloads":6,"Date":"9/23/2012 12:00:00 AM"}, {"Downloads":10,"Date":"9/24/2012 12:00:00 AM"}, {"Downloads":1,"Date":"9/26/2012 12:00:00 AM"}, {"Downloads":1,"Date":"9/29/2012 12:00:00 AM"}, {"Downloads":3,"Date":"10/2/2012 12:00:00 AM"}, {"Downloads":4,"Date":"10/5/2012 12:00:00 AM"}, {"Downloads":1,"Date":"10/6/2012 12:00:00 AM"}, {"Downloads":2,"Date":"10/8/2012 12:00:00 AM"}, {"Downloads":4,"Date":"10/9/2012 12:00:00 AM"}, {"Downloads":3,"Date":"10/10/2012 12:00:00 AM"}, {"Downloads":1,"Date":"10/12/2012 12:00:00 AM"}, {"Downloads":27,"Date":"10/16/2012 12:00:00 AM"}, {"Downloads":2,"Date":"10/17/2012 12:00:00 AM"}, {"Downloads":1,"Date":"10/19/2012 12:00:00 AM"}, {"Downloads":1,"Date":"10/20/2012 12:00:00 AM"}, {"Downloads":9,"Date":"10/21/2012 12:00:00 AM"} ], } }; function formatJSON(source, key1, key2) { var i, l, dest = [], row; for(i = 0, l = source.length; i &lt; l; i++) { row = source[i]; dest.push('[' + row.key1, row.key2 + ']'); } return '[' + dest + ']'; } var downloads= formatJSON(dashboardData.Dashboard.Downloads_By_Date,'Downloads','Date'); var output="&lt;ul&gt;"; output+="&lt;li&gt;" + dashboardData.Dashboard.Total_Downloads + "&lt;/li&gt;"; output+="&lt;/ul&gt;"; document.getElementById("placeholder").innerHTML=downloads; </code></pre> <p>​</p>
