file selector

Description: Selects all elements of type file.

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

:file is equivalent to [type="file"]. 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 $(':file') is equivalent to $('*:file'), so $('input:file') should be used instead.

Additional Notes:

  • Because :file is a jQuery extension and not part of the CSS specification, queries using :file cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use [type="file"] instead.

Example:

Finds all file inputs.
