Is there a way to automatically scroll to the bottom of a div when it first

Looking to enhance my application with a chat feature that automatically scrolls to the bottom of the chat page to display the latest messages.

Utilizing VueJs:

<template>
    <div id="app">
        <div class="comments" v-chat-scroll>
            <div v-for="comment in comments">
                //Content of each comment
            </div>
        </div>
    </div>
</template>

CSS Styling:

.comments {
    margin: 2.5rem auto 0;
    max-width: 60.75rem;
    padding: 0 1.25rem;
    height: 300px;
    overflow-y: scroll;
}

Typescript Implementation:

export default {

    mounted() {
        this.scrollToEnd();
    },

    methods: {

        scrollToEnd() {
            var container = this.$el.querySelector(".comments");
            var scrollHeight = container.scrollHeight;
            container.scrollTop = scrollHeight;
        },
    }
}

Encountering difficulty using scrollTop to set the scrollHeight value for the div. The scrollHeight appears correct (in this case, 300), but scrollTop remains at 0.

Seeking assistance from any willing individuals. Thanks in advance!

Answer №1

My code is functioning perfectly without the need for v-chat-scroll:

new Vue({
  el: '#app',
  data: {
    comments: Array.from({
      length: 50
    }, (_, i) => 'Comment ' + i).concat(['last comment - scroll here'])
  },
  mounted() {
    this.scrollToEnd();
  },

  methods: {

    scrollToEnd() {
      var container = this.$el.querySelector(".comments");
      var scrollHeight = container.scrollHeight;
      container.scrollTop = scrollHeight;
    },
  }
})
.comments {
  margin: 2.5rem auto 0;
  max-width: 60.75rem;
  padding: 0 1.25rem;
  height: 100px;
  overflow-y: scroll;
  border: 1px solid grey;
}

.comment {
  padding: 4px;
  border-top: 1px dotted grey;
}
<div id="app">
  <div class="comments">
    <div v-for="comment in comments">
      <div class="comment">{{comment}}</div>
    </div>
  </div>
</div>

I have also found that the v-chat-scroll directive accomplishes the same task and works flawlessly:

new Vue({
  el: '#app',
  data:{
    comments: Array.from({length: 50}, (_,i) => 'Comment '+i).concat(['last comment - scroll here'])
  },
})
.comments {
  margin: 2.5rem auto 0;
  max-width: 60.75rem;
  padding: 0 1.25rem;
  height: 100px;
  overflow-y: scroll;
  border: 1px solid grey;
}

.comment{
  padding: 4px;
  border-top: 1px dotted grey;
}
<div id="app">
  <div class="comments" v-chat-scroll>
    <div v-for="comment in comments">
      <div class="comment">{{comment}}</div>
    </div>
  </div>
</div>

Utilizing the .scrollIntoView(false) function should smoothly scroll you to the bottom of a specified div container. Below is a demonstration using HTML, JavaScript, and CSS showcasing this functionality.

element = document.getElementsByClassName("text")[0];
for (let i = 0; i < 100; i++) {
  newItem = element.children[0].children[0].cloneNode();
  newItem.innerText = i;
  element.children[0].appendChild(newItem);
}

function scrollBottom(){
  element.children[0].scrollIntoView(false);
}
.text{
  height: 100px;
  overflow-y: scroll;
  border: red solid 
}
<div class="text">
  <div>
  <p>Text Content</p>
  </div>
</div>
<button onClick="scrollBottom()">Scroll to Bottom</button>
