Extracting File Names from File Paths in JavaScript

In web development, it often becomes necessary to extract the file name from a file path. This can be useful when displaying file names in a user interface or performing operations on specific files.

To extract the file name from a full path using JavaScript, you can use the following code snippet:

<code class="javascript">var filename = fullPath.replace(/^.*[\/]/, '');</code>

This code replaces the entire string up to the last occurrence of either a slash (/) or backslash () character with an empty string. As a result, only the file name is left in the filename variable.

For example, if you have the following full path:

C:\Documents and Settings\img\recycled log.jpg

The above code will extract the file name "recycled log.jpg" and store it in the filename variable.

This method works for both Windows-style paths (using backslashes) and Unix-style paths (using slashes), ensuring compatibility across different operating systems.
