Vue v-else-if Directive


Example

Using the v-else-if directive to create a <div> element if the condition is 'true'.

<div v-if="word === 'apple'">
  <img src="/img_apple.svg" alt="apple" />
  <p>The value of the 'word' property is 'apple'.</p>
</div>
<div v-else-if="word === 'pizza'">
  <img src="/img_pizza.svg" alt="pizza" />
  <p>The value of the 'word' property is 'pizza'</p>
</div>

Definition and Usage

The v-else-if directive is used to render an element conditionally.

The v-else-if directive can only be used after an element with v-if, or after another element with v-else-if.

When v-else-if is used on an element, it must be followed by an expression:

  • If the expression evaluates to 'true', the element and all its content is created in the DOM.
  • If the expression evaluates to 'false' the element is destroyed.

When an element is toggled using v-else-if:

  • We can use the built-in <Transition> component to animate when the element enters and leaves the DOM.
  • Lifecycle hooks such as 'mounted' and 'unmounted' are triggered.

Directives for Conditional Rendering

This overview describes how the different Vue directives used for conditional rendering are used together.

Directive Details
v-if Can be used alone, or with v-else-if and/or v-else. If the condition inside v-if is 'true', v-else-if or v-else are not considered.
v-else-if Must be used after v-if or another v-else-if. If the condition inside v-else-if is 'true', v-else-if or v-else that comes after are not considered.
v-else This part will happen if the first part of the if-statement is false. Must be placed at the very end of the if-statement, after v-if and v-else-if.

More Examples

Example 1

Using v-else-if to write "Very few left!" in case there are only 1, 2 or 3 typewriters left in storage.

<p v-if="typewriterCount>3">
  In stock
</p>

<p v-else-if="typewriterCount>0">
  Very few left!
</p>

<p v-else>
  Not in stock
</p>

Example 2

Using v-else-if to show a certain text and image if the sentence contains 'burrito'.

<div id="app">
  <div v-if="text.includes('pizza')">
    <p>The text includes the word 'pizza'</p>
    <img src="img_pizza.svg">
  </div>
  <div v-else-if="text.includes('burrito')">
    <p>The text includes the word 'burrito', but not 'pizza'</p>
    <img src="img_burrito.svg">
  </div>
  <p v-else>The words 'pizza' or 'burrito' are not found in the text</p>
</div>

<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
<script>
  const app = Vue.createApp({
    data() {
      return {
        text: 'I like taco, pizza, Thai beef salad, pho soup and tagine.'
      }
    }
  })
  app.mount('#app')
</script>

Example 3

Using a chain of v-else-if to flip through images, using the <Transition> component to create animations.

App.vue:

<template>
  <h1>mode="out-in"</h1>
  <p>Click the button to get a new image.</p>
  <p>With mode="out-in", the next image is not added until the current image is removed. Another difference from the previous example, is that here we use computed prop instead of a method.</p>
  <button @click="indexNbr++">Next image</button><br>
  <Transition mode="out-in">
    <img src="/img_pizza.svg" v-if="imgActive === 'pizza'">
    <img src="/img_apple.svg" v-else-if="imgActive === 'apple'">
    <img src="/img_cake.svg" v-else-if="imgActive === 'cake'">
    <img src="/img_fish.svg" v-else-if="imgActive === 'fish'">
    <img src="/img_rice.svg" v-else-if="imgActive === 'rice'">
  </Transition>
</template>

<script>
export default {
  data() {
    return {
      imgs: ['pizza', 'apple', 'cake', 'fish', 'rice'],
      indexNbr: 0
    }
  },
  computed: {
    imgActive() {
      if(this.indexNbr >= this.imgs.length) {
        this.indexNbr = 0;
      }
      return this.imgs[this.indexNbr];
    }
  }
}
</script>

<style scoped>
  .v-enter-active {
    animation: swirlAdded 0.7s;
  }
  .v-leave-active {
    animation: swirlAdded 0.7s reverse;
  }
  @keyframes swirlAdded {
    from {
      opacity: 0;
      rotate: 0;
      scale: 0.1;
    }
    to {
      opacity: 1;
      rotate: 360deg;
      scale: 1;
    }
  }
  img {
    width: 100px;
    margin: 20px;
  }
  img:hover {
    cursor: pointer;
  }
</style>
