Is There Really a Difference Between window.location and document.location?

Window.location vs. Document.location: Differences and Usage

The web page object model (DOM) provides various properties and methods to access and manipulate elements and information on a web page. Among these are window.location and document.location, which both allow interaction with the current URL and its components.

Are They the Same?

According to the World Wide Web Consortium (W3C), window.location and document.location are two names for the same global object that represents the current location of the document (the web page you're viewing). They should, therefore, refer to the same object.

Cross-Browser Compatibility

However, in reality, some older browsers may exhibit inconsistencies in their behavior regarding these properties. To ensure cross-browser compatibility and safety, it's recommended to use window.location instead of document.location.

In practice, window.location offers a wider range of methods and properties for manipulating the URL, such as:

window.location.href // Gets or sets the entire URL
window.location.protocol // Gets the protocol (e.g., "https:")
window.location.host // Gets the domain and port (e.g., "example.com:8080")
window.location.pathname // Gets the path (e.g., "/directory/page.html")
window.location.search // Gets the query string (e.g., "?utm_source=google")

By relying on window.location, you can ensure consistent access and manipulation of the current URL across different browsers.
