:only-of-type JQ Home  <<  Selectors  <<  :only-of-type

Only of type child selector.

Shorthand version $(':only-of-type')

Description

The :only-of-type selector matches elements that have no siblings with the same element name.

  • Only unique child elements will be selected.
  • If this selector is not preceded by another selector the universal selector ("*") is implied and so the whole DOM will be searched. Use another selector as in the examples below to narrow the search and improve performance.
