Publishing Websites on IIS
- To publish a website, create a home page named Default.htm or Default.asp and place it in the default web directory, typically located at \Inetpub\wwwroot.
- FTP publishing requires files to be moved to the \Inetpub\Ftproot directory; visitors can access via computer name or IP.
Domain Names
- A domain name uniquely identifies a website, such as microsoft.com, and must be registered in a DNS system.

Learning Outcomes
- Understanding how to create SPAs using AngularJS and manage UI interactions through its components is critical for modern web development.
AngularJS Overview
- AngularJS is a JavaScript framework for building dynamic web applications.
- It utilizes modules that contain components including directives, services, filters, and templates.
- Documentation includes external resources and guides on various AngularJS topics.
AngularJS APIs
- Organized into modules featuring directives, services, filters, providers, templates, and global APIs.
- Offers testing mocks for enhancing application testing processes.
- APIs can be accessed for further learning and implementation.
AngularJS Animations
- Supports animated transitions using CSS for directives like ngRepeat, ngSwitch, and ngView.
- The $animate service facilitates custom directives with animation capabilities.
- Animations can be triggered during the lifecycle of directives, promoting a responsive user experience.
AJAX in AngularJS
- AJAX allows for retrieving information from a database and sending user details to a server without reloading the page.
- Utilizes XMLHttpRequest object for direct server communication, enhancing application performance.
- Reduces the number of full page reloads, improving user-friendliness.
Event Driven Programming
- Based on interactions where events control program flow.
- Utilizes event listeners and handlers to improve responsiveness.
- Suitable for setting up event-driven architectures alongside RESTful APIs, ensuring data integrity.
Data Binding
- Two-way data binding automatically synchronizes the model and view.
- Changes in the model update the view, and vice versa, ensuring real-time data reflection.
- Simplifies user interactions in web applications, enhancing usability.
Single Page Applications (SPAs)
- SPAs dynamically rewrite requested pages rather than completely loading new ones, allowing for a smoother user experience.
- Code (HTML, JavaScript, CSS) is retrieved in a single page load, reducing necessary page refreshes.
- Heavily relies on AJAX for communication with back-end servers, significantly improving load times and responsiveness.
Directive Usage in AngularJS
- Directives can be invoked using Element name, Attribute, Class, or Comment.
- Each directive can have a restrict property that limits how it can be called.
- Default directive restriction allows both Element names and attributes; customization is possible to refine invocation methods.
AngularJS Directives
- A directive is defined in AngularJS to create reusable components.
- Directives can be invoked by Element names, Attributes, Classes, or Comments.
- Legal restrictions for directive invocation:
- E: Element name
- A: Attribute
- C: Class
- M: Comment
- Default restriction is EA, allowing invocation through both Element names and attributes.
- Setting the restrict property to "A" limits invocation to attributes only.
Event-Driven Programming in AngularJS
- Event-driven programming mimics human interactions, controlling application flow based on event occurrences.
- Events are monitored by event listeners that trigger event handlers or callback functions.
- Enhances program responsiveness and flexibility, ideal for applications using RESTful APIs.
- AngularJS promotes two-way data binding and data integrity in real-time.
jQuery Selectors and Event Handling
- jQuery selectors allow targeting specific elements:
-
$(":animated")
: Selects currently animated elements. - $("[href]"): Selects elements with a href attribute.
-
$(":button")
: Targets button elements. -
$(":even")
: Selects even-indexed elements. -
$(":odd")
: Selects odd-indexed elements.
-
- Event handling example:
- Clicking the "Hide" button will hide a paragraph.
- Clicking the "Show" button will display the paragraph.
jQuery Form Validation
- jQuery is commonly used for form data validation.
- Validations help identify incomplete input data before server submission.
- A form can be validated using specific rules set in jQuery.
JavaScript Programming Concepts
- JavaScript is structured to handle various programming elements:
-
Conditional Statements: Perform different actions based on decisions.
- Examples include IF…ELSE, Nested Structures, and Ternary Operators.
- Selection Statements: Handle multiple options using Switch structures.
- Functions can take parameters, enabling dynamic behavior.
- Iterative functions are used for repeating actions.
-
Conditional Statements: Perform different actions based on decisions.
Learning Outcomes
- At the end of the lesson, students will learn:
- Writing programs using conditional statements.
- Utilizing selection statements for multiple options.
- Creating functions and passing parameters effectively.
- Basic data input and handling within JavaScript.
- Understanding data type conversions associated with JavaScript programming.
JavaScript Strings
- Strings can be defined using single or double quotes.
- Quotes within strings must differ from the surrounding quotes, e.g.,
"It's alright"
or'He is called "Gamini"'
.
JavaScript Numbers
- Only one type of number exists in JavaScript, which can be integer or decimal.
- Use scientific notation for very large or small numbers, e.g.,
123e5
(12,300,000) and123e-5
(0.00123).
JavaScript Booleans
- Booleans represent two values:
true
orfalse
. - Example comparison:
(x == y)
istrue
ifx
andy
are equal, otherwisefalse
.
JavaScript Events and Functions
- JavaScript can execute on user interaction, such as clicking HTML elements.
- Assign JavaScript to HTML events like
onclick
to trigger functionalities upon user actions.
setInterval() Method
-
setInterval()
repeats a specified function at defined time intervals. - Example implementation to display time every second using
myTimer
function andsetInterval()
.
clearTimeout() Function
- Used to stop the execution of a function initiated by
setInterval()
. - Relies on the variable returned by
setInterval()
to clear the function call.
jQuery Validation
- Forms can be validated using rules defined for each input field, ensuring criteria like required fields and correct email format.
- Customize validation error messages for improved user feedback during form submission.
Web Hosting and Maintenance
- The lesson extends knowledge about hosting websites and maintaining them remotely through various platforms.
- Linux servers are known for stability and a wide feature set, providing a foundation for web hosting.
Web Servers
- Web servers respond to client requests by delivering resources, like HTML pages.
- Two main types discussed are Apache HTTP Server and Microsoft IIS, both suitable for testing web applications locally.
Internet Service Provider (ISP)
- An ISP provides customers with internet access, facilitating browsing and web interactions.
AngularJS Directives
- AngularJS allows directives to be invoked via elements, attributes, classes, or comments.
- Directives can be restricted to specific invocation methods by setting the
restrict
property.
Event-Driven Programming in AngularJS
- This programming model reacts to events controlled by user interactions.
- Event listeners monitor events and execute designated handlers, enhancing application flexibility.
- Suitable for interfacing with RESTful APIs, facilitating data integrity and synchronization.
