Similar to HTML DOM events, React allows handling user interactions through various events like click<\/code>, change<\/code>, and mouseover<\/code>.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Adding Events in React<\/h2>\n\n\n\n

In React, event names use camelCase syntax, unlike standard HTML. Event handlers in React are written inside curly braces.<\/p>\n\n\n\n

HTML:<\/strong><\/p>\n\n\n\n

<button onclick="triggerAction()">Click Me!<\/button><\/pre><\/div>\n\n\n\n
React:<\/strong><\/p>\n\n\n\n
<button onClick={triggerAction}>Click Me!<\/button><\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Defining Event Handlers<\/h2>\n\n\n\n
Here’s how to define an event handler within a component:<\/p>\n\n\n\n
function ActionButton() {\n  const triggerAction = () => {\n    alert("Action Triggered!");\n  };\n\n  return (\n    <button onClick={triggerAction}>Click Me!<\/button>\n  );\n}\n\nconst root = ReactDOM.createRoot(document.getElementById('root'));\nroot.render(<ActionButton \/>);<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Passing Arguments to Event Handlers<\/h2>\n\n\n\n
To pass arguments to an event handler, use an arrow function.<\/p>\n\n\n\n
Passing the string “Success!” as an argument to the triggerAction<\/code> function:<\/p>\n\n\n\n
function ActionButton() {\n  const triggerAction = (message) => {\n    alert(message);\n  };\n\n  return (\n    <button onClick={() => triggerAction("Success!")}>Click Me!<\/button>\n  );\n}\n\nconst root = ReactDOM.createRoot(document.getElementById('root'));\nroot.render(<ActionButton \/>);<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
React Event Object<\/h2>\n\n\n\n
Event handlers also have access to the event object that triggered the action. This is useful for handling more complex events.<\/p>\n\n\n\n
Using an arrow function to manually pass the event object:<\/p>\n\n\n\n
function ActionButton() {\n  const triggerAction = (message, event) => {\n    alert(event.type);\n    \/\/ 'event' represents the React event that triggered the function, in this case the 'click' event.\n  };\n\n  return (\n    <button onClick={(event) => triggerAction("Success!", event)}>Click Me!<\/button>\n  );\n}\n\nconst root = ReactDOM.createRoot(document.getElementById('root'));\nroot.render(<ActionButton \/>);<\/pre><\/div>\n","protected":false},"excerpt":{"rendered":"
