How to Create a Select Dropdown in Vue with Incremental Intervals of 15 Minutes

Are you transitioning from EJS to Vue.js and finding yourself puzzled over how to create a dropdown that increments in 15-minute intervals? This is a common requirement, especially when displaying time in selectable formats like minutes. In this guide, we'll explore how to accomplish this using Vue's powerful reactivity system.

The Problem: Converting EJS to Vue.js

In EJS, you may have written a loop that looks something like this:

This code generates a dropdown of time options, from 0 to 60 minutes, in increments of 15 minutes. But as you move to Vue.js, you might wonder how to replicate this functionality.

Solution Overview: Utilizing Computed Properties

Vue.js provides a simple and effective way to create dynamic lists with its v-for directive. To generate memory-efficient data, like a list of time intervals, we can make use of computed properties.

Step-by-Step Solution

Here's how you can implement the desired functionality in Vue 3.

1. Set Up Your Vue Application

First, you'll need to set up a Vue app. You can include Vue via a CDN link in your HTML file:

Conclusion

By utilizing computed properties in Vue.js, we can easily create dropdowns for time intervals without the verbosity of traditional loops. This method not only makes your code cleaner but also leverages Vue's reactivity, ensuring that any changes in data are automatically reflected in the UI.

Now you can implement your 15-minute increments smoothly in your Vue applications!
