Jquery exclusion method

There are many jquery selectors. There are many ways to select a DOM. How can we exclude a certain element set? The following are examples:

(1) Select All img elements to exclude the number of elements in class = phpernote:

$ ('Img: not (. phpernote) '). length (); // or $ ('img'). not ('. phpernote'). length ();

(2) obtain the number of li elements without class = com under id = phpernote

$ ('# Phpernote li: not (. com )'). size (); // or $ ('# phpernote li '). not ('. com '). length ();

(3) set the background of the li element of all odd rows under id = phpernote

$ ('# Phpernote li'). not (': even'background .css ('background-color', 'red ');
