Certificate Associate in Web Development – Document Object Model

CAWD Document Object Model

This course is primarily teaching modern HTML in the context of web applications. The Document Object Model, or DOM, is a convention for describing the structure of an HTML document, and it’s at the heart of interacting with the browser.

Conceptually, the DOM is a tree. A tree consists of nodes: every node has a parent (except for the root node), and zero or more child nodes. The root node is the document, and it consists of a single child, which is theelement. Theelement, in turn, has two children: theelement and theelement. Every node in the DOM tree (including the document itself) is an instance of the Node class.

The concept of a tree is straightforward and intuitive, and lends itself to similarly intuitive terminology. A node’s parent is its direct parent (that is, not a “grandparent”) and a child is a direct child (not a “grandchild”). The term descendant is used to refer to a child, or a child’s child, or so on. The term ancestor is used to refer to a parent, the parent’s parent, and so on.

Learning Objectives

Upon completion of the course, participants should be able to:

  • Apply get methods (getElementById, getElementsByClassName, and getElementsByTagName )to quickly locate specific HTML elements
  • Query DOM Elements using CSS selectors (querySelector and querySelectorAll)
  • Access and modify DOM elements
  • Create new nodes using the createElement function

Who should attend

This course will help beginners, programmers, application developers and software engineers pick the right strategy for developing cross-platform web applications that run on a variety of desktop computers as well as mobile devices. The primary audience is developers who need to learn how to develop web applications using the HTML5 stack.

Web Applications

Web Developers build web applications. A web application is one that helps an organization run its business online. ​​Most web applications are built in a three-tier architecture that consists of three important layers: data, logic, and presentation. In web applications, the application structure usually breaks down to database, server, and client, while in modern web development; it can also be broken into database, server logic, client logic, and client UI.

Dynamic web pages are known as pages that are created as soon as a call is sent to the server. So data can be built interactively into the sites. They are particularly helpful when you need to react to user inputs. Forms can be evaluated immediately and the content of the next page can be shown. The application possibilities are nearly unlimited. Whether and to which extent databases are used depends on the goal. Dynamic web pages actually do not need a database.

A popular paradigm for implementing this model is the Model-View-Controller (MVC) architectural pattern. In the MVC paradigm, the logic, data, and visualization are separated into three types of object, each handling its own tasks. The View handles the visual part, taking care of user interaction. The Controller responds to system and user events, commanding the Model and View to change appropriately. The Model handles data manipulation, responding to requests for information or changing its state according to the Controller’s instructions.
