:not() Selector
Categories: Selectors > Basic Filter
not selector
Description: Selects all elements that do not match the given selector.
  • version added: 1.0jQuery( ":not(selector)" )
    selector: A selector with which to filter by.
    
All selectors are accepted inside :not(),  for example: :not(div a) and :not(div,a).
    
Additional Notes
    
The .not() method will end up providing you with more readable selections than pushing complex selectors or variables into a :not() selector filter. In most cases, it is a better choice.
  
Example:
Finds all inputs that are not checked and highlights the next sibling span.  Notice there is no change when clicking the checkboxes since no click events have been linked.
