Browser Object Model
The Browser Object Model (BOM) is a collection of objects provided by web browsers to JavaScript to interact with the browser and control the browser window. The BOM includes objects such as the window
object, the location
object, the navigator
object, and the screen
object, among others.
Here is a brief description of some of the key objects in the BOM:
window
: Thewindow
object is the top-level object in the BOM and represents the browser window. It provides methods and properties for controlling the browser window, such as resizing the window, opening new windows, and accessing the document object.location
: Thelocation
object represents the current URL of the browser window and provides methods and properties for working with URLs, such as getting and setting the URL, reloading the page, and navigating to a new page.navigator
: Thenavigator
object provides information about the browser and the user’s system, such as the browser name and version, the operating system, and the user’s language preferences.screen
: Thescreen
object provides information about the user’s screen, such as the screen width and height, the color depth, and the available screen space.
In addition to these objects, the BOM also includes other objects for interacting with the browser, such as the history
object for navigating the browser history, the document
object for working with the current HTML document, and the XMLHttpRequest
object for making asynchronous HTTP requests.
It’s worth noting that the BOM is not part of the official JavaScript language specification, and different browsers may implement it differently or provide additional objects or features.
