:button Selector
Categories: jQuery Extensions | Form
jQuery(':button')
Description: Selects all button elements and elements of type button.
-
jQuery(':button')
version added: 1.0
An equivalent selector to $(":button")
using valid CSS is $("button, input[type='button']")
.
Note:
Because:button
is a jQuery extension and not part of the CSS specification, queries using :button
cannot take advantage of the performance boost provided by the native DOM querySelectorAll()
method. To achieve the best performance when using :button
to select elements, first select the elements using a pure CSS selector, then use .filter(":button")
.
-
Find all button inputs and mark them.
HTML:
<form> <fieldset> <input type="button" value="Input Button"/> <input type="checkbox" /> <input type="file" /> <input type="hidden" /> <input type="image" /> <input type="password" /> <input type="radio" /> <input type="reset" /> <input type="submit" /> <input type="text" /> <select><option>Option<option/></select> <textarea></textarea> <button>Button</button> </fieldset> </form> <div> </div>
CSS:
textarea { height:35px; } div { color: red; } fieldset { margin: 0; padding: 0; border-width: 0; } .marked { background-color: yellow; border: 3px red solid; }
Code:
var input = $(":button").addClass("marked"); $("div").text( "For this type jQuery found " + input.length + "." ); $("form").submit(function () { return false; }); // so it won't submit
