Get Url Segment Javascript

Understanding URL Segments in Javascript

URL segments are a fundamental concept in web development that allow us to access specific data within a URL. In the context of JavaScript, understanding URL segments is essential when building applications that require dynamic routing, handling complex query parameters, and managing URL redirections.

The basic format of a URL segment is as follows:


In this example, the URL contains two segments: “some-path” and “some-segment.” We can extract these segments and their corresponding query parameters using JavaScript’s built-in URL object.

Here’s an example of how we can access and manipulate these segments:

const url = new URL(window.location.href);
const pathSegments = url.pathname.split(‘/’).filter(segment => segment !== ”);
const queryParams = Object.fromEntries(url.searchParams);

In this code snippet, we first create a new URL object that represents the current window location. We then extract the path segments by splitting the “pathname” property and removing any empty segments. Lastly, we extract the query parameters using the “searchParams” property and convert them to an object using the built-in “Object.fromEntries” method.

With these segments and parameters, we can perform various operations such as redirecting the user to a different URL, updating the query parameters dynamically, or extracting specific data such as IDs or slugs from the URL.

Overall, understanding URL segments in JavaScript is crucial for building robust web applications that require dynamic routing and handling of complex data.

Learn to Extract URL Segments in Javascript

Are you trying to extract specific parts of a URL in your Javascript code? Knowing how to extract URL segments can be very useful when building web applications. Here’s how you can do it:

const url = window.location.href; // Get the current URL
const segments = url.split('/'); // Split the URL into segments using the forward slash delimiter
const segment1 = segments[0]; // Get the first segment
const segment2 = segments[1]; // Get the second segment
const segment3 = segments[2]; // Get the third segment
// ... and so on for each segment you need

In this example, we first get the current URL using the window.location.href property. We then use the split() method to split the URL into segments using the forward slash delimiter. Finally, we can access each segment using its index in the segments array.

With this knowledge, you can easily extract any segment of a URL in your Javascript code. This can be especially useful when working with dynamic URLs and routing in web applications.

How to Get Specific Parts of a URL in Javascript

Retrieving specific parts of a URL in JavaScript can be done using the built-in window.location object, which provides easy access to all the components of a URL.

To get the current URL of the page:

var currentURL = window.location.href;

To get the protocol of the URL:

var protocol = window.location.protocol;

To get the hostname of the URL:

var hostname = window.location.hostname;

To get the pathname of the URL:

var pathname = window.location.pathname;

To get the search parameter of the URL:

var search =;

To get the hash portion of the URL:

var hash = window.location.hash;

These are the basic ways to get the specific parts of a URL in JavaScript. By using these objects, you can easily manipulate or retrieve essential parts of a URL whenever necessary.

Exploring the Benefits of URL Segments in Web Development with Javascript

URL Segments are an integral part of web development with Javascript. URL segments are those parts of the URL that come after the domain name, and separated by a slash (/). They are also known as “path segments”.

One of the most significant benefits of using URL segments in web development is the ability to create clean and user-friendly URLs. This is because URLs with meaningful and descriptive path segments are easier to read and understand by both users and web crawlers.

Another benefit of using URL segments is that they help in organizing website content. By using path segments, developers can group related content together and create a hierarchical structure for their website. This makes it simpler for search engines to crawl and rank website content, leading to better SEO performance.

Furthermore, URL segments help in creating dynamic content, as developers can use them to pass variables and parameters between different web pages. This enables users to interact with the website and access personalized content such as user profiles and search results.

Overall, URL segments are an essential tool for web developers, allowing them to create clean and organized websites that are easier to use. By leveraging the power of Javascript, developers can create dynamic content that engages users and enhances the user experience.

Tips and Tricks for Working with URL Segments in Javascript

When working with URLs in JavaScript, it’s important to understand how to extract and manipulate various segments of the URL. This can be particularly useful when working with dynamic URLs, where certain segments may change depending on user input.

Here are some tips and tricks for working with URL segments in JavaScript:

  • Use the `window.location` property to access the full URL of the current page.
  • To extract a specific segment of the URL, such as the hostname or pathname, use the corresponding properties of the `window.location` object. For example, `window.location.hostname` will return the hostname of the page.
  • The `` property can be used to extract the query string part of the URL, including any parameters passed in through GET requests.
  • To parse the query string into a more readable format, use the `URLSearchParams()` constructor.
  • If you need to modify a specific segment of the URL, you can construct a new URL based on the original URL and modify the desired segment using string manipulation functions such as `replace()` or `substring()`.

Overall, understanding how to work with URL segments in JavaScript can greatly increase your flexibility and control when building dynamic web applications.

Creating Dynamic Links with URL Segments Using Javascript

In web development, sometimes we need to create dynamic links with URL segments to pass data between different pages or components. This can be achieved easily using JavaScript. By adding URL segments to a link, we can pass data as parameters to the target page or component.

Let’s see an example of how we can create dynamic links with URL segments using JavaScript:

// Get the value of an input field
let inputVal = document.querySelector('#inputField').value;

// Create a dynamic link with URL segment using the input value
let link = document.createElement('a');
link.href = '' + inputVal;
link.textContent = 'Search';

// Append the link to a container element
let container = document.querySelector('#container');

In the above example, we first fetched the value of an input field using JavaScript. Then, we created a dynamic link with a URL segment using the input value. Finally, we added the link to a container element.

This is just one example of how we can create dynamic links with URL segments using JavaScript. With a little bit of creativity, we can use this technique to pass any kind of data between different pages or components in our web application.

Best Practices for Handling URL Segments in Javascript Programming.


When it comes to working with URLs in Javascript programming, handling URL segments is a crucial aspect. URL segments are the parts of a URL that come after the domain name and the path. In order to effectively handle URL segments, it’s important to follow some best practices. Here are some tips to help you handle URL segments in Javascript programming:

1. Use the window.location object to access the current URL.
2. Use the URLSearchParams API to parse query parameters.
3. Use the parse() method of the URL object to parse the URL string.
4. Use regular expressions to validate URL segments before processing them.
5. Avoid hardcoding URL segments in your code, as this can make it hard to maintain your code over time.
6. Use a library, such as URI.js, to simplify URL handling.

By following these best practices, you can ensure that your Javascript code effectively handles URL segments, leading to more reliable and maintainable code.
