To upload files asynchronously using jQuery, you can use the FormData object in combination with the $.ajax() method. Here’s how it works:
Steps to Upload Files Asynchronously:
Create an HTML form: Include a file input field to allow users to select files for upload.
Capture the file(s): Use jQuery to detect when a file is selected.
Use FormData: Create a FormData object and append the selected file(s) to it.
Send the file(s): Use the $.ajax() method to send the FormData object to the server asynchronously.
Key Points:
Asynchronous Nature: The file upload happens in the background without reloading the page.
Headers: Ensure the Content-Type header is set to false in the AJAX request to allow FormData to set it automatically.
Cross-Browser Support: Modern browsers support the FormData object.
This method allows you to upload files efficiently while keeping the user experience seamless.
