Get part of the url pathname via JavaScript regex

Get part of the url pathname via JavaScript regex

If you want to extract a specific part of the URL pathname using JavaScript and a regular expression, you can use the following example:

// Example URL: https://www.example.com/products/category/electronics/item/123 // Get the current URL pathname const pathname = window.location.pathname; // Define a regular expression to match the category part in the pathname const categoryRegex = /\/products\/category\/([^/]+)/; // Use the regex to extract the category const match = pathname.match(categoryRegex); // Check if a match is found if (match) { const category = match[1]; // Extracted category value console.log("Category:", category); } else { console.log("Category not found in the URL pathname."); }

This example assumes a URL structure where the category is part of the pathname, following the pattern "/products/category/{category}". Adjust the regular expression (/\/products\/category\/([^/]+)/) based on your specific URL structure.

Here, ([^/]+) captures one or more characters that are not a forward slash (/) and extracts it as a group. The extracted category value can be accessed using match[1].

Make sure to adapt the regular expression to match your specific URL structure and adjust the code accordingly.
