Editor to share with you how html uses objectURL to deal with files. I hope you will get something after reading this article. Let's discuss it together.

Working with files using objectURL

There is a special method called URL.createobjecturl () that creates a unique URL from a file. You can also use the URL.revokeObjectURL () method to release it.

The URL.revokeObjectURL () static method is used to release a previously existing URL object created by calling URL.createObjectURL (). When you finish using a URL object, you should call this method to let the browser know that there is no need to keep a reference to the file in memory. FileUploader.addEventListener ('change', (event) = > {const files = event.target.files; const file = files [0]; const img = document.createElement (' img'); imageGrid.appendChild (img); img.src = URL.createObjectURL (file); img.alt = file.name;}) After reading this article, I believe you have a certain understanding of "how html uses objectURL to process documents".
