:checkbox Selector

Categories: jQuery Extensions | Form

jQuery(':checkbox')

Description: Selects all elements of type checkbox.

  • jQuery(':checkbox')

    version added: 1.0

$(':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.

Note:

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.
  • Finds all checkbox inputs.
