JQuery Basics

Creating a File Upload Form

HTML Setup

First, let's create a simple HTML form for our file upload.

html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>JQuery File Upload</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <form action="upload.php" method="post" enctype="multipart/form-data">
        <label for="file">Select a File:</label>
        <input type="file" name="file" id="file">
        <input type="submit" value="Upload File" id="upload-btn">
    </form>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <script src="script.js"></script>
</body>
</html>

JQuery Implementation

Now, let's add JQuery to handle our file upload.

javascript

$(document).ready(function() {
    $('#upload-btn').click(function(e) {
        e.preventDefault(); // Prevent form submission

        // Get the selected file
        var file = $('#file')[0].files[0];

        // Create a FormData object
        var formData = new FormData();
        formData.append('file', file);

        // AJAX request to upload the file
        $.ajax({
            url: 'upload.php',
            data: formData,
            processData: false,
            contentType: false,
            type: 'POST',
            success: function(data) {
                console.log(data);
                alert('File uploaded successfully!');
            },
            error: function() {
                console.log('Error occurred while uploading the file.');
            }
        });
    });
});

📝 Note: In the above example, upload.php is a PHP script that handles the file upload on the server-side. You can find various PHP file upload examples online if you're not familiar with it.
