Get the Current Directory Name in JavaScript#

If you are working with JavaScript and need to retrieve the current directory name, there are a few ways you can achieve this. Let's take a look at some of the most common methods.

Method 1: Using window.location.pathname#

The easiest way to get the current directory name in JavaScript is to use the window.location.pathname property. This property returns the path and file name of the current page, including the initial slash (/).

var currentPath = window.location.pathname;
var directoryName = currentPath.substring(currentPath.lastIndexOf('/') + 1);
console.log(directoryName);

The code above retrieves the current path using window.location.pathname, then uses the substring() method to extract the directory name from the path. The lastIndexOf() method is used to find the position of the last slash (/) in the path, and substring() is used to extract everything after the last slash.

Method 2: Using document.URL and Regular Expressions#

Another way to get the current directory name in JavaScript is to use the document.URL property and regular expressions. This method is a bit more complicated than the previous one, but can be used if you need more control over how the directory name is extracted.

var currentUrl = document.URL;
var directoryName = currentUrl.match(/.*\/(.*)/)[1];
console.log(directoryName);

The code above retrieves the current URL using document.URL, then uses a regular expression to extract the directory name from the URL. The regular expression matches everything up to the last slash (/) in the URL, then captures everything after the last slash using parentheses.

Method 3: Using window.location.href and String Manipulation#

Finally, you can also get the current directory name in JavaScript by using the window.location.href property and string manipulation. This method is similar to the first method, but uses a different approach to extract the directory name.

var currentUrl = window.location.href;
var directoryName = currentUrl.substring(0, currentUrl.lastIndexOf('/')).split('/').pop();
console.log(directoryName);

The code above retrieves the current URL using window.location.href, then uses substring() to extract everything before the last slash (/) in the URL. It then uses split() to split the resulting string by slashes (/), and pop() to get the last element in the resulting array, which should be the directory name.

In conclusion, these are three of the most common ways to get the current directory name in JavaScript. You can use any of these methods depending on your specific needs and preferences.
