What is the best way to implement a scroll-into-view feature for a newly added list item in Vue.js?

I am currently utilizing vueJS to create a task viewing application.

My goal is to make the div containing the list focus on the newly added list item immediately after adding a new task.

Here's the HTML code from my template for the task list:

<ul>
  <li
          v-for="task in filteredTasks"
          :key="task.id"
          id="taskListItem"
          ref="taskListItem"
          class="taskList d-flex align-items-center justify-content-between"
        >
        <span> {{ task.name }} </span>
  </li>
</ul>

And here are the computed and methods functions I'm using to add and filter tasks:

JavaScript


 computed : {
   filteredTasks() {
      return this.selectedUsers.length
        ? this.filteredOnProgress.filter((task) =>
            task.userIds.some((id) => this.selectedUsers.includes(id))
          )
        : this.filteredOnProgress;
    },
}

methods : {
    addTaskName(){
      if (this.newTaskName.name != "") {
      this.addTask(this.newTaskName)
      this.newTaskName.name = ""
      }
     }
 },

Answer №1

This is how I tackled my issue:

I assigned an ID of "taskListul" to my unordered list.

Then, I included the following function in my methods:

  scrollToEndOfTask() {
      const taskScroll = this.$el.querySelector("#taskListul")
      const scrollHeight = taskScroll.scrollHeight
      taskScroll.scrollTop = scrollHeight
    },

In order to implement automatic scrolling, I invoked this function within the update method of the vue instance:

updated() {
    this.scrollToEndOfTask()
  },
