How can get length on checked checkbox array javascript
<pre><code>&lt;form name='form1' &gt;
&lt;input type=checkbox name='cbox[]' /&gt;
&lt;/form&gt;

&lt;script&gt;    
var checkbox = document.getElementsByName('ckbox[]')
    var ln = checkbox.length
    alert(ln)
&lt;/script&gt;
</code></pre>

<p>How can I count only the checked checkboxes with javascript or jQuery?</p>
