[javascript] Scroll to bottom of div with Vue.js

I have a Vue component with several elements in it. I want to automatically scroll to the bottom of that element when a method in the component is called (basically, do the same as in Scroll to bottom of div?). However, I haven't found the way to get the element within my component and modify scrolTop

I'm currently using Vue 2.0.8

1. Use ref attribute on DOM element for reference

<div class="content scrollable" ref="msgContainer">
    <!-- content -->
</div>

2. You need to setup a WATCH

  data() {
    return {
      count: 5
    };
  },
  watch: {
    count: function() {
      this.$nextTick(function() {
        var container = this.$refs.msgContainer;
        container.scrollTop = container.scrollHeight + 120;
      });
    }
  }

3. Ensure you're using proper CSS

.scrollable {
  overflow: hidden;
  overflow-y: scroll;
  height: calc(100vh - 20px);
}

The solution did not work for me but the following code works for me. I am working on dynamic items with class of message-box.

scrollToEnd() {
            setTimeout(() => {
                this.$el
                    .getElementsByClassName("message-box")
                    [
                        this.$el.getElementsByClassName("message-box").length -
                            1
                    ].scrollIntoView();
            }, 50);
        }

Remember to put the method in mounted() not created() and add class message-box to the dynamic item.

setTimeout() is essential for this to work. You can refer to https://forum.vuejs.org/t/getelementsbyclassname-and-htmlcollection-within-a-watcher/26478 for more information about this.

2021 easy solution that won't hurt your brain... use el.scrollIntoView()

Here is a fiddle.

This solution will not hurt your brain having to think about scrollTop or scrollHeight, has smooth scrolling built in, and even works in IE.

scrollIntoView() has options you can pass it like scrollIntoView({behavior: 'smooth'}) to get smooth scrolling.

methods: {
  scrollToElement() {
    const el = this.$el.getElementsByClassName('scroll-to-me')[0];

    if (el) {
      // Use el.scrollIntoView() to instantly scroll to the element
      el.scrollIntoView({behavior: 'smooth'});
    }
  }
}

Then if you wanted to scroll to this element on page load you could call this method like this:

mounted() {
  this.scrollToElement();
}

Else if you wanted to scroll to it on a button click or some other action you could call it the same way:

<button @click="scrollToElement">scroll to me</button>

The scroll works all the way down to IE 8. The smooth scroll effect does not work out of the box in IE or Safari. If needed there is a polyfill available for this here as @mostafaznv mentioned in the comments.

I had the same need in my app (with complex nested components structure) and I unfortunately did not succeed to make it work.

Finally I used vue-scrollto that works fine !

For those that haven't found a working solution above, I believe I have a working one. My specific use case was that I wanted to scroll to the bottom of a specific div - in my case a chatbox - whenever a new message was added to the array.

const container = this.$el.querySelector('#messagesCardContent');
        this.$nextTick(() => {
          // DOM updated
          container.scrollTop = container.scrollHeight;
        });

I have to use nextTick as we need to wait for the dom to update from the data change before doing the scroll!

I just put the above code in a watcher for the messages array, like so:

messages: {
      handler() {
        // this scrolls the messages to the bottom on loading data
        const container = this.$el.querySelector('#messagesCard');
        this.$nextTick(() => {
          // DOM updated
          container.scrollTop = container.scrollHeight;
        });
      },
      deep: true,
    }, 

Here is a simple example using #ref to scroll to the bottom of a div.

/*_x000D_
Defined somewhere:_x000D_
  var vueContent = new Vue({_x000D_
      el: '#vue-content',_x000D_
      ..._x000D_
 */_x000D_
_x000D_
var messageDisplay = vueContent.$refs.messageDisplay;_x000D_
messageDisplay.scrollTop = messageDisplay.scrollHeight;

<div id='vue-content'>_x000D_
  <div ref='messageDisplay' id='messages'>_x000D_
    <div v-for="message in messages">_x000D_
      {{ message }}_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

Notice that by putting ref='messageDisplay' in the HTML, you have access to the element through vueContent.$refs.messageDisplay

In the related question you posted, we already have a way to achieve that in plain javascript, so we only need to get the js reference to the dom node we want to scroll.

The ref attribute can be used to declare reference to html elements to make them available in vue's component methods.

Or, if the method in the component is a handler for some UI event, and the target is related to the div you want to scroll in space, you can simply pass in the event object along with your wanted arguments, and do the scroll like scroll(event.target.nextSibling).

I tried the accepted solution and it didn't work for me. I use the browser debugger and found out the actual height that should be used is the clientHeight BUT you have to put this into the updated() hook for the whole solution to work.

data(){
return {
  conversation: [
    {
    }
  ]
 },
mounted(){
 EventBus.$on('msg-ctr--push-msg-in-conversation', textMsg => {
  this.conversation.push(textMsg)
  // Didn't work doing scroll here
 })
},
updated(){              <=== PUT IT HERE !!
  var elem = this.$el
  elem.scrollTop = elem.clientHeight;
},

If you need to support IE11 and (old) Edge, you can use:

scrollToBottom() {
    let element = document.getElementById("yourID");
    element.scrollIntoView(false);
}

If you don't need to support IE11, the following will work (clearer code):

scrollToBottom() {
    let element = document.getElementById("yourID");
    element.scrollIntoView({behavior: "smooth", block: "end"});
}
