JavaScript BOM: Master the Browser Object Model | Window, Location, History & More
🚀 Dive into the world of the JavaScript Browser Object Model (BOM)! This video provides a comprehensive guide for beginners to understand the core concepts of the BOM and how to use it to manipulate the browser window.
We'll start with the fundamental `window` object, exploring its crucial properties like `innerWidth`, `innerHeight`, `outerWidth`, `outerHeight`, `screenX`, `screenY` and scroll positions. Learn how to use methods like `open()`, `close()`, `focus()`, `scrollBy()`, and `scrollTo()` to control the window's behavior. We'll also explain window dialogs using `alert()` and `confirm()` and how to handle events. 💻
Next, we'll dive into the `location` object to understand and manage URLs, including the protocol, hostname, pathname and query parameters. 🧭 Also, discover how the `history` object allows navigation through browser history. ⏪⏩ We'll explore the methods `back()`, `forward()`, and state management. You will also learn how frames work and how to communicate between frames using `postMessage()`.🖼️
Finally, we will cover the `screen` object and its properties like `width`, `height`, `availWidth`, and `availHeight`. 📺 You will learn about the window timing methods like `setTimeout()`, `setInterval()` and `requestAnimationFrame()` for efficient coding.⏱️
