:buttonS2C Home « Selectors « :button
Form button selector.
Shorthand version $(':button')
Description
The :button selector, selects all button and type button elements.
- Being a jQuery extension the
:buttonpseudo selector is not part of any current CSS specification. Therefore:buttoncannot take advantage of the performance boost provided by the native DOMquerySelectorAll()method. - The same results can be achieved with valid CSS using
$("button, input[type='button']"), 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 button elements.
In the example below we apply an orange background to 'button' elements within the form filtered by class 'ourform'.
$(function(){
$('.ourform').submit(function () { return false; }); // disable submit
$('#btn1').on('click', function() {
$('.ourform: button').css('backgroundColor', 'orange');
});
});
