How to Set Maxlength for Textarea with Countdown in Vue.js

Published on April 16, 2020 30 sec read

In this short article, we’re going to learn how to set maxlength for textarea in Vue.js with the remaining length countdown.

We’ll use v-model to get data from textare and will count remaining length using v-on:keyup method.

Let’s see the full example:

  <div id="app">
    <p>Total Remaining: <span v-bind:class="{'text-danger': generateErr }">{{totalRemainCount}}</span></p>
    <textarea class="form-control" v-on:keyup="liveCountDown" v-model="theMessage" placeholder=""></textarea>

 export default{
    data: function () {
      return {
        limitmaxCount: 160,
        totalRemainCount: 160,
        theMessage: '',
        generateErr: false
    methods: {
      liveCountDown: function() {
        this.totalRemainCount = this.limitmaxCount - this.theMessage.length;
        this.generateErr = this.totalRemainCount < 0;
That’s it. Thank you. 🙂
