input selector

Description: Selects all input, textarea, select and button elements.

version added: 1.0jQuery( ":input" )

The :input selector basically selects all form controls.

Additional Notes:

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").

Example:

Finds all input elements.

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>input demo</title>
  <style>
  textarea {
    height: 25px;
  }
    </style>
  <script src="https://code.jquery.com/jquery-4.0.0.js"></script>
</head>
<body>
<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>
<script>
var allInputs = $( ":input" );
var formChildren = $( "form > *" );
$( "#messages" ).text( "Found " + allInputs.length + " inputs and the form has " +
  formChildren.length + " children." );
$( "form" ).on( "submit", function( event ) {
  event.preventDefault();
} );
</script>
</body>
