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>
