How do i split into a block of 3?
<p>I want to separate a set of 3 numbers with a comma and set the value to a textarea, i have tried this but it just brings the values concatenated like this "5.685.685.85", i want it to appear like this "5.68, 5.68, 5.85"</p>

<pre><code>var once = window['tma'+kj].toFixed(2);
for (var li=0; li&lt;once.length; ++li) {
    $('#comments').append(once[li]); //div tag, it shows concateneted
    $('#com').val(once[li]); //textarea id, brings blank
}
</code></pre>
