Issue with Event Delegation and Dynamic Element Creation in Vanilla JavaScript
I'm prototyping a solution and Hey everyone, I'm running into an issue that's driving me crazy. I'm having trouble with event delegation when dynamically creating elements in my application using vanilla JavaScript. I have an event listener set up on a parent `<div>` that is supposed to handle clicks on `<button>` elements inside it. However, when I create new buttons after the initial page load, the event listener does not trigger for those buttons. Here's a simplified version of my code: ```javascript const container = document.getElementById('button-container'); // Set up event delegation on the parent container container.addEventListener('click', function(event) { if (event.target.tagName === 'BUTTON') { console.log(`Button ${event.target.innerText} clicked`); } }); // Function to add a new button dynamically function addButton() { const newButton = document.createElement('button'); newButton.innerText = 'New Button'; container.appendChild(newButton); } // Call this function after a delay to simulate user action setTimeout(addButton, 1000); ``` After calling `addButton()`, I expected to see a log message when clicking the new button, but nothing happens. I’ve confirmed that the new button exists in the DOM using the developer tools. I also checked if the event listener is correctly attached to the container. Is there something I'm missing with how event delegation works? I’ve also tried using `event.stopPropagation()` in other parts of my code, but that's not related to this specific issue. Any help would be appreciated! I'm using vanilla JavaScript without any libraries, and this should work according to my understanding of event bubbling and delegation. I'm working on a service that needs to handle this. Has anyone else encountered this? Am I approaching this the right way?
