clone table row

Question

How can i use javascript (i assume) to clone a table row like ive beautifully illustrated in the picture below?

Solution

You can hookup a live event to all the buttons. If you give them a class of clone for instance the following will work.

$('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 );
});

Please Note: If you have elements in the table row with id's you will need to do a .each through them and set them to a new value otherwise you will end up with duplicate id's in the dom which is not valid and can play havoc with jQuery selectors

You can do this like so
