Today, we found that the original filter tag can be used in this way.

Not (expr | ele | fn): removes the elements that match the specified expression from the set of matching elements.

Use in the demo below:Var $ category = $ (". sub-category-box> ul> li: gt (2): not (: last) "); // if the index in the list is greater than 2

Filter (expr | obj | ele | fn): r filters out the set of elements that match the specified expression. This method is used to narrow the matching range. Multiple Expressions separated by commas

$ ("Ul> li "). filter (": contains ('canon '),: contains ('sony'),: contains ('samsung ')"). toggleClass ("promoted"); // filter the labels containing canon, Sony, and Samsung in the li tags, and set the class

The two methods are used in the demo. Suddenly, jQuery is really powerful.
