How to disable input conditionally in Vue.js

in Code Write a comment

In this tutorial, you’ll learn how to disable input field conditionally in Vue.js.

For example, we’ve got a form that asks the user to verify the email address. If entered correctly, this form becomes disabled and a feedback message pops up (I literally just came up with this example).

Here’s how the HTML template will look like:

<div id="app">
  <h2>Please, verify your email address:</h2>
  <input type="text" id="email" name="name" v-model="email" :disabled="validated ? '' : disabled" /><br><br>
  <h4 v-if="validated">
    Thank you for verifying your email address
  </h4>
</div>

Vue.js component

new Vue({
  el: "#app",
  data: {
    email: null,
    correctEmail: '[email protected]'
  },
  methods: {
  },
  computed: {
    validated() {
      if (this.email === this.correctEmail) {
      	return true
      }
    },
  }
})

The result:
