How to clean cloned input value?
<p>I have a table with function "add new column". When it is pressed, a new column is added, but it has previous column values. How can I clean cloned input value?</p>

<p>My table looks like:</p>

<pre><code>&lt;tr&gt;
&lt;td&gt;&lt;input style="width:80%" id="row_name2" type="text" name="option[0][]" value="" /&gt;&lt;/td&gt;
&lt;/tr&gt;
</code></pre>

<p>jquery:</p>

<pre><code>var table = line.parentNode.parentNode;
        jQuery.each( jQuery('tbody tr',table) , function(i, obj){
            jQuery('td:eq('+(cols-2)+')',obj).after(
                jQuery('td:eq('+(cols-2)+')',obj).clone()

            );
        });
</code></pre>
