Description

Course Program: DOM and Events

1. Introduction to the DOM (Document Object Model)

• What is the DOM and how it represents the structure of an HTML document.

• How JavaScript interacts with the DOM to manipulate HTML and CSS.

• Accessing the DOM using document object.

2. Selecting DOM Elements

• Methods to select elements: getElementById(), getElementsByClassName(), querySelector(), querySelectorAll().

• Understanding the difference between single and multiple element selection.

3. Manipulating DOM Elements

• Modifying element content: innerHTML, textContent, and value.

• Changing element attributes using setAttribute() and getAttribute().

• Changing CSS styles using style property.

4. Creating and Removing Elements

• Creating new DOM elements using createElement(), appendChild(), and insertBefore().

• Removing elements using removeChild() and remove().

• Cloning elements with cloneNode().

5. Event Handling

• Introduction to events in JavaScript.

• Adding event listeners using addEventListener().

• Common events: click, submit, keydown, mouseover, etc.

• Event object: properties and methods (e.g., target, preventDefault()).

6. Event Propagation and Bubbling

• Understanding event propagation: capturing vs bubbling phases.

• Using stopPropagation() and preventDefault() to control event flow.

• Delegated event handling for more efficient event management.

7. Forms and Input Handling

• Accessing form elements using DOM.

• Handling form events: submit, input, change.

• Validating form input using JavaScript.

8. Dynamic DOM Manipulation

• Building interactive pages: showing/hiding elements, updating content dynamically.

• Adding or removing classes to elements using classList.

• Creating dynamic content based on user input.

9. Practical Exercises

• Creating a simple to-do list with DOM manipulation (add/remove tasks).

• Implementing a form validation script.

• Building interactive elements like a modal popup or accordion menu.

10. Final Project

• Developing a mini-project where students use DOM manipulation and events to create an interactive web page (e.g., a dynamic gallery or interactive quiz).

Expected Outcomes:

• Solid understanding of the DOM and its relationship with HTML/CSS.

• Ability to manipulate DOM elements and handle user interactions via events.

• Proficiency in creating dynamic, interactive web pages using JavaScript.
