clone table row, append random or sequential number to ID
<p>So i have this code</p>

<pre><code>$('input.clone').live('click', function(){
   //put jquery this context into a var
   var $btn = $(this);
   //use .closest() to navigate from the buttno to the closest row and clone it
   var $clonedRow = $btn.closest('tr').clone();
   //append the cloned row to end of the table

   //clean ids if you need to
   $clonedRow.find('*').andSelf().filter('[id]').each( function(){
       //clear id or change to something else
       this.id += '_clone';
   });

   //finally append new row to end of table
   $btn.closest('tbody').append( $clonedRow );
});
</code></pre>

<p>Problem is, each row i clone gets named whatever _clone
How would i write this so that each time i run the function, it picks either a random or more idealy sequential number to append to the id isntead of "_clone"</p>
