How to Loop X Times with v-for in VueJS?

Vue.js is a progressive JavaScript framework widely used for building user interfaces. One of its core features is the v-for directive, which allows you to iterate over data or render a block of elements a specified number of times. we will explore various ways to loop X times using v-for in Vue.js. This includes setting up a Vue.js application, running the code, and viewing the output.

The v-for directive in Vue.js is used to render a list of items or iterate a specific number of times in the DOM. If you need to loop a set number of times (X times), there are multiple ways to achieve this. Vue.js allows you to loop through arrays or generate ranges dynamically.

These are the following approaches:

Steps to Create the Vue.js Application

Step 1: Install Vue CLI

• First, you need to install Vue CLI if you don’t have it already

npm install -g @vue/cli

Step 2: Create a Vue.js Project

• Run the following command to create a new Vue.js project

vue create v-for-loop-demo

• Select the default options or customize them according to your project needs. Once the project is created, navigate to the project folder

cd v-for-loop-demo

Step 3: Run the Development Server

• Start the development server to serve your project locally

npm run serve

Project Structure:

Updated Dependencies:

  "dependencies": {
    "core-js": "^3.6.5",
    "vue": "^3.0.0"
  },

• Make sure to update the dependencies if required by running

npm install

Using an Array of Length X

The simplest way to loop X times is to create an array of the required length and use v-for to iterate over it. You can create an empty array with the desired number of elements and loop through it using v-for.

Syntax:

<div v-for="n in X" :key="n">
  <!-- Loop content -->
</div>

Example: This example shows the use of an Array to show the iteration.

// App.vue
<template>
  <div>
    <div v-for="n in 5" :key="n">Loop iteration: {{ n }}</div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      X: 5,
    };
  },
};
</script>

Output:

Using Array Constructor to Create a Range

Another approach is to use the Array constructor to directly create an array of a specific length and populate it with values using map or keys().

Syntax:

<div v-for="n in Array.from({ length: X }, (_, i) => i + 1)" :key="n">
  <!-- Loop content -->
</div>

Example: This example shows the use of Array Constructor to Create a Range.

// App.vue
<template>
  <div>
    <div v-for="n in Array.from({ length: 5 }, (_, i) => i + 1)" :key="n">
      Loop iteration: {{ n }}
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      X: 5,
    };
  },
};
</script>

Output:
