Making API Calls

To generate a QR code using the GoQR API, you can call the following endpoint: https://api.qrserver.com/v1/create-qr-code/?size=150x150&data= + qrtext.value;

Replace qrtext.value with the content you want to encode into the QR code.

For example, to create a QR code with the text "example", you would call: https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=example

You can find detailed documentation and examples on the official GoQR API documentation.

JavaScript Function Example

Here's a JavaScript function that utilizes the GoQR API to generate a QR code based on user input:

function GenerateQR() {
    if (qrtext.value.length > 0) { // Check if input text is not empty

        // Generate QR code image using QR Server API
        qrimage.src = "https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=" + qrtext.value;

        // Show the container with the QR image
        displaybox.classList.add("show-img");

        // Update download link href to the generated QR code image
        downloadButton.href = qrimage.src;
        downloadButton.style.display = "block"; // Show the download button
    } else {
        // If input text is empty, add error class to input field for visual feedback
        qrtext.classList.add("error");

        // Remove error class after 1 second to remove visual feedback
        setTimeout(() => {
            qrtext.classList.remove("error");
        }, 1000);
    }
}
