Introduction In this tutorial, you will learn how to create a modern file selector with drag-and-drop functionality and image preview using Tailwind CSS and JavaScript.
Building the File Selector
- Start by building a simple file selector with a "Choose files" button and a dropzone.
- Use Tailwind CSS to style the file selector and give it a modern look.
- Add a hidden file input and a click event listener to the "Choose files" button to handle file selection.
Adding Drag-and-Drop Support
- Add event listeners for dragover, dragleave, and drop events to the dropzone to handle drag-and-drop file uploads.
- Use JavaScript to prevent the default behavior of these events and add custom styling to the dropzone when a file is being dragged over it.
- Use the DataTransfer object to access the files that were dropped onto the dropzone.
Displaying Selected Images
- Use the URL.createObjectURL() method to display selected images in a preview area.
- Use JavaScript to add a "Remove" button to each selected image to allow users to remove images as needed.
- Update the preview area and the selected files count whenever an image is added or removed.
Conclusion By the end of this tutorial, you will have a fully functional file selector with drag-and-drop support and image preview that you can use in your own projects. Whether you're a beginner looking to improve your JavaScript skills or an experienced developer looking for a new way to handle file uploads, this tutorial has something for you.
