How to Get File Name from URL in Javascript

As a web developer, you may come across situations where you need to extract the file name from a URL in JavaScript. The good news is that it’s easy to accomplish with a few lines of code. In this tutorial, we’ll show you how to do just that.

First, let’s take a look at a simple function that extracts the file name from a URL:

function getFileNameFromUrl(url) {
  // Find the last occurrence of the forward slash character.
  const fileNameStart = url.lastIndexOf("/") + 1;

  // Extract the file name from the URL.
  const fileName = url.substring(fileNameStart);

  // Return the file name.
  return fileName;

This function takes a URL as input and returns the file name. It works by finding the position of the last forward slash in the URL and then extracting the file name that follows it.

To use this function, you can simply pass in a URL as a parameter and store the returned file name in a variable. Here’s an example:

const url = "";
const fileName = getFileNameFromUrl(url);
console.log(fileName); // Output: "file.txt"

Now that you know how to extract the file name from a URL in JavaScript, you can use this knowledge to make your web development projects more efficient.

In conclusion, extracting the file name from a URL in JavaScript is a straightforward process that can be accomplished with just a few lines of code. By using the getFileNameFromUrl function we’ve shown you in this tutorial, you’ll be able to extract file names from URLs in no time.
