Design a Decimal to Binary Converter in VueJS
The Decimal to Binary Converter is a simple web application built using Vue.js that allows users to convert decimal numbers to binary format. It provides a user-friendly interface for the easy conversion of decimal numbers into a binary representation.
Prerequisites
Approach
- Create a new HTML file named index.html. Include the necessary CDN links for the Vue.js and Tailwind CSS.
- Design the layout using HTML elements such as the <div>, <input>, <button>, and <p>. Use appropriate classes from the Tailwind CSS for styling.
- Apply Tailwind CSS classes to style the elements for a modern and responsive design.
- Use utility classes for the spacing, borders, and colors as needed. Initialize a new Vue instance with the el option set to #app.
- Define data properties for the storing the decimal number input and binary conversion result.
- Implement a method to convert the decimal number to the binary upon button click. Use the parseInt() and toString(2) functions to the perform the conversion.
- Add validation to the ensure that a valid decimal number is entered before conversion. Display an alert message if the input is invalid.
- Show the binary equivalent of the entered decimal number below the input field after conversion.
