:fileS2C Home « Selectors « :file
Form file selector.
Shorthand version $(':file')
Description
The :file selector, selects all elements of type file.
- Being a jQuery extension the
:filepseudo selector is not part of any current CSS specification. Therefore:filecannot take advantage of the performance boost provided by the native DOMquerySelectorAll()method. - The same results can be achieved using the Attribute Equals Selector via
$('[type=file]'), without the hit to performance. - If this selector is not preceded by another selector, the universal selector ("*") is implied and so the whole DOM will be searched. Use another selector as in the example below to narrow the search and improve performance.

Selects all elements of type file.
In the example below we apply an orange background to 'file' elements within the form.
$(function(){
$('.ourform').submit(function () { return false; }); // disable submit
$('#btn1').on('click', function() {
$('form input:file').css('backgroundColor', 'orange');
});
});
