Creating a Seamless 6-Digit Passcode Input in Plain JavaScript

Building a sleek, user-friendly 6-digit passcode input can make user verification workflows much smoother. This tutorial walks you through creating such a system with plain JavaScript, focusing on dynamic input handling, seamless navigation, and paste support. Let’s dive into the essentials.

Step 1: Dynamic Input Creation

Start by dynamically creating six input fields to hold each digit of the passcode

const wrapper = document.querySelector('.code-wrapper');
const numFields = 6;

// Create 6 input fields
for (let i = 0; i < numFields; i++) {
    const input = document.createElement('input');
    input.type = 'text';
    input.maxLength = 1;
    input.className = 'code-input';
    wrapper.appendChild(input);
}

Each input field is restricted to one character using maxLength.

Step 2: Managing Input Behavior

Handle navigation between fields, support pasting, and validate when all fields are filled

const fields = document.querySelectorAll('.code-input');

// Handle typing and navigation
fields.forEach((field, index) => {
    field.addEventListener('input', () => {
        if (field.value && index < fields.length - 1) fields[index + 1].focus();
        checkCompletion();
    });

    field.addEventListener('keydown', (event) => {
        if (event.key === 'Backspace' && !field.value && index > 0) {
            fields[index - 1].focus();
        }
    });

    // Handle paste
    field.addEventListener('paste', (event) => {
        const pasteData = (event.clipboardData || window.clipboardData).getData('text').trim();
        if (/^\d{6}$/.test(pasteData)) {
            [...pasteData].forEach((digit, idx) => fields[idx] && (fields[idx].value = digit));
            checkCompletion();
        }
    });
});

Step 3: Validating and Verifying the Code

When all six fields are filled, concatenate the values and trigger verification

const checkCompletion = () => {
    const code = Array.from(fields).map((field) => field.value).join('');
    if (code.length === 6) verifyCode(code);
};

const verifyCode = (code) => {
    console.log('Verifying code:', code);
    setTimeout(() => {
        if (code === '123456') {
            alert('Code verified!');
        } else {
            alert('Invalid code. Try again.');
            fields.forEach((field) => (field.value = ''));
            fields[0].focus();
        }
    }, 1000); // Simulate backend delay
};

This 6-digit passcode system supports typing, navigation, pasting, and error handling, offering a smooth user experience. It’s a perfect addition to verification flows, easy to extend with backend integration or additional features like animations.

Writer RAG tool: build production-ready RAG apps in minutes

RAG in just a few lines of code? We’ve launched a predefined RAG tool on our developer platform, making it easy to bring your data into a Knowledge Graph and interact with it with AI. With a single API call, writer LLMs will intelligently call the RAG tool to chat with your data.

Integrated into Writer’s full-stack platform, it eliminates the need for complex vendor RAG setups, making it quick to build scalable, highly accurate AI workflows just by passing a graph ID of your data as a parameter to your RAG tool.
