Unexpected Behavior with Event Delegation and Dynamic Elements in Vue 3
After trying multiple solutions online, I still can't figure this out. I'm experiencing unexpected behavior when trying to implement event delegation on dynamically created elements in my Vue 3 application. I have a list of items that can be filtered, and when I click on a filter button, new items are added to the DOM. However, the event listeners for these new items don’t seem to fire as expected. I'm using the `v-for` directive to render the list and the `@click` directive to handle the clicks. Here's a simplified version of my code: ```vue <template> <div> <button @click="filterItems">Filter Items</button> <ul> <li v-for="item in filteredItems" :key="item.id" @click="handleItemClick(item)">{{ item.name }}</li> </ul> </div> </template> <script> export default { data() { return { items: [], filteredItems: [] }; }, methods: { filterItems() { // Simulate fetching new items and updating the list this.items = [...this.items, { id: 4, name: 'New Item' }]; this.filteredItems = this.items.filter(item => item.id > 2); }, handleItemClick(item) { console.log('Item clicked:', item); } } }; </script> ``` When I click the filter button, the new items are added to the list, and I can see them rendered in the UI. However, clicking on these new items doesn’t trigger the `handleItemClick` function, while the ones already in the DOM work just fine. I tried using the `v-on` directive instead of `@click`, but it didn't resolve the issue. I'm using Vue 3.2.26 and Vue Router 4.0.9. Could this be related to how Vue manages event listeners on dynamically created elements, or am I missing something in the reactivity system? Any insights would be appreciated.
