selected selector
Description: Selects all elements that are selected.
version added: 1.0jQuery( ":selected" )
The :selected selector works for <option> elements. It does not work for checkboxes or radio inputs; use :checked for them.
Additional Notes:
- Because
:selectedis a jQuery extension and not part of the CSS specification, queries using:selectedcannot take advantage of the performance boost provided by the native DOMquerySelectorAll()method. To achieve the best performance when using:selectedto select elements, first select the elements using a pure CSS selector, then use.filter(":selected").
Example:
Attaches a change event to the select that gets the text for each selected option and writes them in the div. It then triggers the event for the initial text draw.
