Pull Random records from JSON using Javascript

I'm trying to pull information from a json file.  The goal is to get 9 records returned in random order.
My data looks like this (there are 60 different videos):
    {"id":"1", "ytID":"ys7Xnw34T5A", "title":"Video 1", "category":"Category 1"},
    {"id":"2", "ytID":"HlrO8gH7AEY", "title":"Video 2", "category":"Category 2"},
    {"id":"3", "ytID":"NzYp5YGK9vc", "title":"Video 3", "category":"Category 3"},
    {"id":"4", "ytID":"brrTb2zmOYd", "title":"Video 4", "category":"Category 4"}

Open in new window

I pull the data like this:

$.getJSON(url, function(data){
     var firstVideo = data.videos[0].title;
     var firstVideoCode = data.videos[0].ytID;
     var x = 0;
     $.each(data.videos, function(index, videos) {

          if (x < 10){
                //create blockText to display results 
                blockText += '<div class="thumbVids">\
		<a href="#" onclick="getVideo(\'' + videos.ytID + '\')">\
		<img class="vidThumb" src="//i1.ytimg.com/vi/' + videos.ytID + '/hqdefault.jpg" border="0" /></a>\
		<p class="title">' + videos.title + '</p>\

I'm not sure the best way to grab a random sampling.  Any suggestions?  Thanks for your help!

You can try to shuffle your video array before creating blockText for all the videos.
A sample shuffle function based on Fisher and Yates algorithm:
function shuffleArray(arr) {
   var swap = function(i, j) { var tmp = arr[i]; arr[i] = arr[j]; arr[j] = tmp; };
   for (var i = arr.length - 1; i > 0; i--) {
       int j = rand.Next(i + 1);
       swap(i, j);

And then you just need to add up blockText with each videos in the array after shuffling:
      $.each(data.videos, function(index, videos) {
          //create blockText to display results 
          blockText += '<div class="thumbVids"><a href="#" onclick="getVideo(\'' + videos.ytID + '\')"><img class="vidThumb" src="//i1.ytimg.com/vi/' + videos.ytID + '/hqdefault.jpg" border="0" /></a><p class="title">' + videos.title + '</p></div>';
