:enabled Selector

Categories: Selectors > Form Chinese Translation: :enabled Selector

enabled selector

Description: Selects all elements that are enabled.

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

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 $( ":enabled" ) is equivalent to $( "*:enabled" ), so $( "input:enabled" ) or similar should be used instead.

Although their resulting selections are usually the same, :enabled selector is subtly different from :not([disabled]); :enabled selects elements that have their boolean disabled property strictly equal to false, while :not([disabled]) selects elements that do not have a disabled attribute set (regardless of its value).

The :enabled selector should only be used for selecting HTML elements that support the disabled attribute (<button>, <input>, <optgroup>, <option>, <select>, and <textarea>).

Example:

Find all input elements that are enabled.
