In jQuery, the “not” is used to select all elements that do not match the selector.

Examples

  1. $(‘p:not(.class-p1)’) – selects all elements matched by <p> that do NOT have a class name of “class-p1″.
  2. $(‘li:not(:only-child)’) – selects all elements matched by <li> that are NOT the only child of their parent.
  3. $(‘li:not(:first-child)’) – selects all elements matched by <tr> that are NOT the first child of their parent.
