Here, e is a synthetic event. With the arrow function you have to send the event argument manually: Try it on CodePen. Every event handler is passed a SyntheticEvent, which is an object that contains useful metadata related to the event, such as the target element’s value. Handling events in React is simple; events are declared in camelCase in a React app. The code above accesses just that, the target element’s value, and shows it inside a browser alert. Event handlers have access to the React event that triggered the function. The event handlers below are triggered by an event in the bubbling phase. When using React, you generally don’t need to call addEventListener to add listeners to a DOM element after it is created. The target property gets the element on which the event originally occurred, opposed to the currentTarget property, which always refers to the element whose event listener triggered the event. The event.target property can be used in order to implement event delegation. Definition and Usage The target event property returns the element that triggered the event. EventTarget. Since the value attribute is set on our form element, the displayed value will always be this.state.value, making the React state the source of truth.Since handleChange runs on every keystroke to update the React state, the displayed value will update as the user types.. With a controlled component, the input’s value is always driven by the React state. For instance, if you have to define the onclick event, so we take a little different approach and declare onClick event this way in a React application.. React is a popular front-end framework, and it does follow the best practices to make it works hard to make it popular among web developers around the globe. In our example the event is the "click" event. See the SyntheticEvent reference guide to learn more.. To register an event handler for the capture phase, append Capture to the event name; for example, instead of using onClick , you would use onClickCapture to handle the click event in the capture phase. It is different from Event.currentTarget when the event handler is called during the bubbling or capturing phase of the event.. Syntax var theTarget = event.target; Value. React normalizes events so that they have consistent properties across different browsers. React defines these synthetic events according to the W3C spec, so you don’t need to worry about cross-browser compatibility.React events do not work exactly the same as native events. Example. The target property of the Event interface is a reference to the object onto which the event was dispatched. Notice that once again the syntax is different when using arrow functions or not.
