Exploring Vue.JS with Staggered Transitions and Enhancing User Experience with Loading More

The VueJS Guide offers a clever method for using the item's index to create a delayed transition for the items in the data set. You can learn more about it here. While this approach works great when the data set remains static, I'm encountering a challenge with my implementation. I have a "load more" button that fetches additional records and adds them to the array. Due to the delay being based on the index, the new items do not animate immediately - they wait for the existing items to finish animating first. Any suggestions on how to reset the timer effectively between calls?

Appreciate any insights!

Answer №1

  1. Ensure the key attribute is passed correctly. When making an AJAX request to the API server upon pressing the Load More button, each element in the response should have a unique identifier. In this case:

[
  { id: 15, title: 'Page #15' },
  { id: 16, title: 'Page #16' },
  { id: 17, title: 'Page #17' }
]

The unique property in this example is id. It should be used as :key in the v-for loop.

<span v-for="item in items" :key="item.id" class="list-item">
  {{ item }}
</span>

  1. Update the array properly. Use array.push(), array.splice(), or replace the array according to the official guidelines provided at: https://v2.vuejs.org/v2/guide/list.html#Array-Change-Detection

  2. Confirm correct implementation of CSS animation.

Please include code snippets when seeking assistance as it helps in identifying and addressing the issue more effectively.
