:input Selector
Categories: jQuery Extensions | Form
jQuery(':input')
Description: Selects all input, textarea, select and button elements.
-
jQuery(':input')
version added: 1.0
The :input
selector basically selects all form controls.
Note:
Because:input
is a jQuery extension and not part of the CSS specification, queries using :input
cannot take advantage of the performance boost provided by the native DOM querySelectorAll()
method. To achieve the best performance when using :input
to select elements, first select the elements using a pure CSS selector, then use .filter(":input")
.
-
Finds all input elements.
HTML:
<form> <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> </form> <div id="messages"> </div>
CSS:
textarea { height:25px; }
Code:
var allInputs = $(":input"); var formChildren = $("form > *"); $("#messages").text("Found " + allInputs.length + " inputs and the form has " + formChildren.length + " children."); // so it won't submit $("form").submit(function () { return false; });
