Here’s the HTML code for the content:
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.
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];
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
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:
- Changing the content of a webpage using
- Manipulating the URL of the current page using
- Opening new windows or tabs in the browser using
- Controlling the back and forward buttons of the browser using
- Adding event listeners to the browser window using
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
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
- Access the full URL: The
hrefproperty returns the complete URL of the page. In our example,
- Retrieve the protocol: The
protocolproperty returns the protocol of the current URL. In our example,
- Get the hostname: The
hostnameproperty returns the hostname of the URL. In our example,
- Fetch the path: The
pathnameproperty returns the path of the URL. In our example,
- Retrieve URL parameters: The
searchproperty returns the query string of the URL. In our example,
- Fetch hash values: The
hashproperty returns the anchor part of the URL. In our example,
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.
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”.
Advanced Techniques for Accessing Page Name
- 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.titleproperty returns the title of the current page, which often includes the page name, while the
document.URLproperty 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.
- 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.
