Interactive Currency Converter using JavaScript

Currency Converter in JavaScript

JavaScript is a powerful programming language that can be used to create a variety of web-based applications, including currency converters. A currency converter is a simple tool that allows users to input an amount in one currency and get the equivalent amount in another currency.

To create a currency converter in JavaScript, you will need to:

1. Create an HTML form with two input fields, one for the amount and one for the currency code.
2. Create a JavaScript function that will handle the currency conversion. This function will take the amount and currency code as input and return the converted amount.
3. Add an event listener to the form's submit button that will call the JavaScript function when the user clicks the button.

Example of a currency converter in JavaScript:

<form id="currency-converter">
  <input type="number" name="amount" placeholder="Amount">
  <input type="text" name="currency" placeholder="Currency Code">
  <input type="submit" value="Convert">
</form>

// JavaScript
function convertCurrency(amount, currencyCode) {
  // Get the exchange rate for the two currencies.
  const exchangeRate = fetch(`https://api.exchangeratesapi.io/latest?base=${currencyCode}`)
    .then(response => response.json())
    .then(data => data.rates.USD);

  // Convert the amount to the desired currency.
  const convertedAmount = amount * exchangeRate;

  // Return the converted amount.
  return convertedAmount;
}

// Add an event listener to the form's submit button.
document.querySelector('#currency-converter').addEventListener('submit', event => {
  // Prevent the default form submission.
  event.preventDefault();

  // Get the amount and currency code from the form.
  const amount = event.target.querySelector('input[name="amount"]').value;
  const currencyCode = event.target.querySelector('input[name="currency"]').value;

  // Convert the amount to the desired currency.
  const convertedAmount = convertCurrency(amount, currencyCode);

  // Display the converted amount.
  alert(`The converted amount is ${convertedAmount} USD.`);
});

This is just a simple example, and you can customize it to meet your specific needs. For example, you could add additional features, such as a dropdown list of currencies, or the ability to specify a date for the exchange rate.

Publishing the Currency Converter on a Website

To publish the currency converter on a website, you will need to upload the HTML and JavaScript files to your website's server. Once the files are uploaded, you can link to the HTML file from your website's navigation bar or another page on your website.

Some tips for publishing the currency converter on a website:

• Make sure to validate the form input before submitting it to the JavaScript function. This will help to prevent errors.
• Use a JavaScript library to format the currency values. This will make the currency converter more user-friendly.
• Test the currency converter thoroughly before publishing it on your website. Make sure that it works correctly for all currencies and all exchange rates.

I hope this helps!
