The function presented bellow can be used to shuffle /randomize array items in JavaScript.
// receive an array and return it with the items shuffled /randomized function shuffle(ar){ for(var j, x, i = ar.length; i; j = Math.floor(Math.random() * i), x = ar[--i], ar[i] = ar[j], ar[j] = x); return ar; }- Here is a simple example:
<h4>Example shuffle array in JavaScript</h4> <p>Initial array: ar1 = ['a', 'b', 'c', 1, 2, 3];</p> <button id='btntst'>Test Shuffle Array</button> <script> // receive an array and return it with the items shuffled /randomized function shuffle(ar){ for(var j, x, i = ar.length; i; j = Math.floor(Math.random() * i), x = ar[--i], ar[i] = ar[j], ar[j] = x); return ar; } var ar1 = ['a', 'b', 'c', 1, 2, 3]; //when click on the #btntst, show alert box with the items of ar1 document.getElementById('btntst').addEventListener('click', function(){ ar1 = shuffle(ar1); alert(ar1); }); </script>
<input type="text" value="fixed-value" readonly="readonly" name="a_name" />
