checkbox selector

Description: Selects all elements of type checkbox.

  • version added: 1.0jQuery( ":checkbox" )

$( ":checkbox" ) is equivalent to $( "[type=checkbox]" ). As with other pseudo-class selectors (those that begin with a ":") it is recommended to precede it with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare $(':checkbox') is equivalent to $( "*:checkbox" ), so $( "input:checkbox" ) should be used instead.

Additional Notes:

  • Because :checkbox is a jQuery extension and not part of the CSS specification, queries using :checkbox cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use [type="checkbox"] instead.

Example:

Finds all checkbox inputs.
