:enabled Selector
enabled selector
version added: 1.0jQuery(':enabled')
Description: Selects all elements that are 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') should be used instead.
Example:
Finds all input elements that are enabled.
