input selector

Description: Selects all input, textarea, select and button elements.

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

The :input selector basically selects all form controls.

Additional Notes:

  • Because :input is a jQuery extension and not part of the CSS specification, queries using :input cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :input to select elements, first select the elements using a pure CSS selector, then use .filter(":input").

Example:

Finds all input elements.
