JSON Fetch Random Record

Searched everywhere for this one. Hopefully it will help someone else out...

I was looking for a way to filter a JSON dataset by an ID number. Here goes...

1. Step 1 : Create your JSON Data.
   
   
   var item = [
   { "id": "0", "language": "English"},
   { "id": "1", "language": "Spanish"},
   { "id": "2", "language": "French"},
   { "id": "3", "language": "Hungarian"}
   ];
   


2. Step 2 : Function to find Unique Value:
   
   
   I cant take credit for this one. I found this at : http://stackoverflow.com/questions/604935/how-can-i-filter-json-for-unique-key-name-value-pairs. Here it is...
   
   function getDistinct(o, attr) {
   var answer = {};
   $.each(o, function(index, record) {
   answer[index[attr]] = answer[index[attr]] || [];
   answer[index[attr]].push(record);
   });
   return answer;
   }
   


3. Step 3: Create Random Number
   
   var randNo = Math.floor(Math.random() * 4); (with 4 being the same number of records contained in the JSON Dataset).
   


4. Step 4: Return unique record items
   
   
   $(function() {
   $.each(getDistinct(markers, "id"), function(groupName, recordArray) {
   var firstRecord = recordArray[randNo];
   $('
').html(firstRecord.language).appendTo('#results');
});
});

Finally, the body simply contains an unordered list with an id of results to contain the information.
