Vue.js v-show

in Code Write a comment

In this tutorial you’ll learn how to conditional rendering using v-show.

If you’re already familiar with the v-if directive, you’ll see that v-show is very similar.

v-show directive is used for conditional rendering of the DOM element. The difference is that v-show will always render the element and keep it in the DOM. It will hide an element by toggling the display CSS property of the element.

Whereas, if false, v-if will not render an element in the DOM.

v-show example in Vue.js

HTML

<div id="app">
  <h1 v-if="loggedIn">Welcome back!</h1>
  <h1 v-else>Please log in.</h1>
</div>

Vue.js

new Vue({
  el: "#app",
  data: {
    loggedIn: false
  }
})

Result

If we change change loggedIn to true, the output will be:

We’re using v-else directive to render an “else block” for v-if. You can also use v-else-if directive to chain your v-if statement.

In some cases, you’ll choose v-show directive over v-if. I personally use v-if 90% of the time. Just to prevent leaking of sensitive data and keep the DOM clean.
