In this session, Laisha delves into the Document Object Model (DOM), demystifying the core structure that transforms plain HTML pages into dynamic, interactive web encounters through JavaScript. She also sheds light on NodeList and HTMLCollection, the essential tools for effectively handling clusters of elements.
You know how a remote control brings a television to life by letting you change channels and do cool things? Well, in the web world, JavaScript is like that remote control for your HTML page, making it active and dynamic. And the secret sauce behind this magic is the DOM – the Document Object Model.
So, what's this DOM thing? DOM stands for Document Object Model. It's like the behind-the-scenes framework that JavaScript uses to talk to your browser. Imagine it as the language that JavaScript speaks with your web browser to make things happen on your HTML page.
JavaScript and the browser communicate through a set of tools in this magical interface known as the DOM. These tools include properties, methods, and events. It's like having a language to tell your browser what to do and when to do it.
Okay, how do we get our hands on this DOM magic? Well, accessing the DOM is like reaching for that remote control. In JavaScript, you use commands to grab elements from your HTML page, change their content, or even create new elements. It's like giving instructions to your browser using JavaScript.
