// Get references to HTML elements
const imageInput = document.getElementById("imageInput");
const previewImage = document.getElementById("previewImage");
const imageUploadForm = document.getElementById("imageUploadForm");

// Add an event listener to the file input
imageInput.addEventListener("change", function () {
    const selectedFile = imageInput.files[0];
    
    if (selectedFile) {
        // Display a preview of the selected image
        const reader = new FileReader();
        reader.onload = function (e) {
            previewImage.src = e.target.result;
            previewImage.style.display = "block";
        };
        reader.readAsDataURL(selectedFile);
    }
});

// Add an event listener to the form to handle image submission
imageUploadForm.addEventListener("submit", function (e) {
    e.preventDefault(); // Prevent the form from submitting normally

    // Get the selected image file
    const selectedFile = imageInput.files[0];

    if (selectedFile) {
        // You can now use the selectedFile to upload the image to your server
        // You may use XMLHttpRequest, Fetch API, or other methods to send the file to the server
        // Here's an example using the Fetch API to upload the image to a server endpoint:

        const formData = new FormData();
        formData.append("image", selectedFile);

        fetch("/upload", {
            method: "POST",
            body: formData,
        })
            .then(response => {
                if (response.ok) {
                    // Handle a successful upload
                    console.log("Image uploaded successfully!");
                } else {
                    // Handle an error during upload
                    console.error("Image upload failed.");
                }
            })
            .catch(error => {
                console.error("Error:", error);
            });
    }
});
