formSortable class child class formItem having selected class or not my jquery is

if ($('.formSortable').find('formItem').hasClass('selected')) {
                   alert("hi");
               }

Answer 1

This:

if( $('.formSortable').find('.formItem.selected').length > 0 ) {
    alert( 'hi' );
}

Or this:

$('.formSortable').find('.formItem.selected').length == 0 || alert( 'hi' );

Should work fine.

But if per the title you really meant child of '.formSortable' then use .children() instead of .find():

if( $('.formSortable').children('.formItem.selected').length > 0 ) {
    alert( 'hi' );
}

Or:

$('.formSortable').children('.formItem.selected').length == 0 || alert( 'hi' );

Answer 2

if ($('.formSortable').find('.formItem').hasClass('selected')) {
                   alert("hi");
               }

you have missed the . before formitem .
