    The simplest way to get the first result of find is with good old [index] operator:

    $('.comment').find('form')[0];

    Works like a charm!

    You can use either 

    $(this).closest('.comment').find('form').eq(0).toggle('slow');

    or

    $(this).closest('.comment').find('form:first').toggle('slow');

    I use

    $([selector]).slice(0, 1)

    because it's the most explicit way to select a slice of a query and because it can be easily modified to match not the first element but the next, etc.

    Use :first selector like below :

    $(this).closest('.comment').find('form:first').toggle('slow');

    using jquery simply use:

        $( "form" ).first().toggle('slow');
