Question

In HTML, how can I make a button that reverse sorts a massive.. $m = explode($s)
form_method=”POST”

Answer 1

I assume you mean client-side, not just HTML. If so, use Array.sort().

“Massive” is a completely relative term, but I have tested Array.Sort with complex object sorts for arrays containing a couple thousand items with no issues.

Simplified, it looks like this.

<input type="button" onclick="PerformSort()" />

<script>

function PerformSort()
{

var arr = [];

// populate 'arr' with items to sort

arr.sort();

// output sorted results to DOM

}

</script>
