Introduction to Current Page Name in JavaScript

In JavaScript, you can easily get the current page name using the window.location.pathname property. This property returns the path and filename of the current web page, which can be useful for various purposes such as navigation, tracking, and so on.

To extract the current page name from the path, you can use various JavaScript methods such as substring, lastIndexOf, or split, depending on your specific needs. For example:

// Get the full path and filename
var fullPath = window.location.pathname;

// Get the page name only
var pageName = fullPath.substring(fullPath.lastIndexOf('/') + 1);

// Alternative way to get the page name only
var parts = fullPath.split('/');
var pageName = parts[parts.length - 1];

Once you have the current page name in JavaScript, you can use it to update the page title, highlight the current menu item, send analytics data to a server, or perform other dynamic actions. Just keep in mind that the page name may not always be accurate or consistent across different browsers or devices, so you should test your code thoroughly and handle any possible edge cases.

Understanding the Document Object Model (DOM)

The Document Object Model (DOM) is a programming interface for web documents. It represents the page so that programs can change the document structure, style, and content. The DOM represents the document as nodes and objects – that way, programming languages can interact with the page.

A web page is document represented in a browser in form of HTML Document Object Model hierarchy. Understanding the Document Object Model (DOM) is crucial to develop dynamic and interactive websites. With the help of Document Object Model, we can manipulate specific parts of a web page (such as the text within a specific element) and respond to user interactions on the web page (such as clicking a button).


Leveraging Window Object for Page Manipulation

The Window object in JavaScript represents the browser’s window. It is the global object in the browser and is used to manipulate the browser window as well as the page that is loaded inside it.

Through the Window object, we can change the content, styling, and behavior of a webpage. Here are some of the manipulations that can be made using the Window object:

  1. Changing the content of a webpage using document property
  2. Manipulating the URL of the current page using location property
  3. Opening new windows or tabs in the browser using window.open() method
  4. Controlling the back and forward buttons of the browser using history property
  5. Adding event listeners to the browser window using addEventListener() method

The Window object provides developers with a powerful set of tools to manipulate and customize the browsing experience. With its various properties and methods, we can create complex web applications that are rich in functionality and user interaction.

Using location object for retrieving Page Information

The location object in JavaScript is used to obtain various information about the current URL loaded in the browser. It allows us to retrieve the current page name, URL parameters, hash values, and much more. In this article, we will focus on how to use the location object to retrieve page information.

Let’s say we have a URL: https://www.example.com/blog?id=123#comments. To retrieve information from this URL using the location object:

  1. Access the full URL: The href property returns the complete URL of the page. In our example, location.href will return "https://www.example.com/blog?id=123#comments".
  2. Retrieve the protocol: The protocol property returns the protocol of the current URL. In our example, location.protocol will return "https:".
  3. Get the hostname: The hostname property returns the hostname of the URL. In our example, location.hostname will return "www.example.com".
  4. Fetch the path: The pathname property returns the path of the URL. In our example, location.pathname will return "/blog".
  5. Retrieve URL parameters: The search property returns the query string of the URL. In our example, location.search will return "?id=123".
  6. Fetch hash values: The hash property returns the anchor part of the URL. In our example, location.hash will return "#comments".

The location object is very useful when we want to retrieve different parts of the current URL dynamically. By using the properties provided by the location object, we can create powerful scripts that can operate on the current URL with ease.

How to Retrieve Page Name using JavaScript

Retrieving the current page name in JavaScript can be useful for various purposes, such as tracking user behavior or dynamically modifying the content based on the current page.

To retrieve the page name, you can use the location.pathname property, which contains the path of the current URL. Then, you can extract the page name from the path by using string methods:

const path = location.pathname;
const pageName = path.substring(path.lastIndexOf('/') + 1);

The code above extracts the page name from the location.pathname property by finding the last occurrence of the forward slash (“/”) and taking the substring after that. For example, if the current URL is “https://example.com/blog/post-1”, the pageName variable will contain “post-1”.

By using this technique, you can easily retrieve the current page name in JavaScript and use it for your specific needs.


Advanced Techniques for Accessing Page Name

There are several methods for accessing the current page name in JavaScript. In addition to the basic methods, there are also advanced techniques that can be used:

  • Using window.location.pathname: This method returns the path of the current URL without the domain name. By using the split method, you can extract the page name from the path.
  • Using Regular Expressions: Regular expressions can be used to match and extract the page name from the current URL.
  • Using window.location.hash: This method returns the anchor part of the URL, including the # symbol. By using the split method, you can extract the page name from the anchor part.
  • Using the Document Object: The document object provides several properties that can be used to access the current page name. The document.title property returns the title of the current page, which often includes the page name, while the document.URL property returns the complete URL of the current page, which can be parsed to extract the page name.

These advanced techniques may require more code than the basic methods, but they provide greater flexibility and can be used in a wider range of scenarios.

Common Pitfalls to Avoid When Retrieving Page Name.

Retrieving the current page name in JavaScript is a common task, but there are some pitfalls to avoid to ensure accurate results. Here are some common mistakes to avoid:

  • Not using the correct method to retrieve the page name. Depending on the browser and the implementation, there are different methods to retrieve the current page name. Make sure you are using the correct method for your specific use case.
  • Not considering URL parameters. If your page name includes URL parameters, make sure to account for them in your code.
  • Not accounting for URL encoding. If your page name includes special characters or spaces, make sure to properly encode them.
  • Not testing for edge cases. It’s important to test your code in various scenarios, including pages with different URL structures or when navigating within a single-page app.

By avoiding these common pitfalls, you can ensure accurate retrieval of the current page name in JavaScript.
