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
:fileis a jQuery extension and not part of the CSS specification, queries using:filecannot take advantage of the performance boost provided by the native DOMquerySelectorAll()method. For better performance in modern browsers, use[type="file"]instead.
Example:
Finds all file inputs.
