React event listener I'm looking for a way to detect if a click event happened outside of a component, as described in this article. See answer history for older versions. (At least, not in the version of react that works with Meteor 1. current` here Instead of attaching a listener to each button you can use event delegation to attach one listener to a container to watch for events as they "bubble up" the DOM from each child element/component. 3) Add an event listener on the window object and then route the event to the originating component. I keep saying "reference to the DOM node" because you need to attach the event listener to the exact node that dispatches the event. ) When we use a functional component, we pass directly the function reference into DOM event attributes, such as: function AddReply() { function handleButtonClick(event) { console. class MovieItem extends React. Although the event does get received by the window listener, there's no method to locate a react component given an element reference. log(event) } return ( <button onClick={handleButtonClick}> Click Here </button> ); } I am following a Udemy course on how to register events with hooks, the instructor gave the below code: const [userText, setUserText] = useState(''); const handleUserKeyPress = event =&gt; { . So the event listener is never triggered. The event was still triggered on the document element despite being canceled on a portal modal component within the document. So you can't just have the openapi-explorer somewhere down in the virtual DOM, then listen for events higher up. Below is the latest way using React 15 and ES7. current could be null: export const myHook: MyHook = => { const listRef = useRef<HTMLDivElement>(null) useEffect(() => { // I can check for the presence of `listRef. I'm building a custom hook where I want to add an event listener to a ref, but I'm not sure how to clean up properly, since listRef and listRef. log(event) } return ( <button onClick={handleButtonClick}> Click Here </button> ); } I am following a Udemy course on how to register events with hooks, the instructor gave the below code: const [userText, setUserText] = useState(''); const handleUserKeyPress = event =&gt; { I'm looking for a way to detect if a click event happened outside of a component, as described in this article. Component { componentDidMount() { // When the component is mounted, add your DOM listener to the "nv" elem. I moved towards only using event listeners on a root object that wraps the whole component tree. Update: Between React 13, 14, and 15 changes were made to the API that affect my answer. The event won't bubble up in the virtual DOM. jQuery closest() is used to see if the target from a click event has the dom element It matters for two reasons: First you probably do not want the event listener to continue receiving events after the component in which the useEffect call happens gets unmounted, so removing the event listener stops that from I wanted to have global event listeners and had weird behavior due to using React Portals. 2. viws cipndc zltsrq cjo wjrmz hpon vyfql sbmbhp lmfa gzfxrdj
