Using the `oninput` event handler with `onkeyup`/`onkeydown` as its fallback

Read Original

This technical article discusses the standardized HTML5 `oninput` event for detecting user input in JavaScript. It explains why `oninput` is preferable to `onkeyup`/`onkeydown`, covers browser support (including IE9), and details a practical fallback technique. The method involves binding both `oninput` and `onkeydown` events, then removing the keydown handler once `oninput` fires, avoiding complex feature detection. Code examples are provided in plain JavaScript and as a jQuery plugin.
