HTML helpers in MVC

HTML helpers in MVC

MVC includes standard helpers for the most common types of HTML elements.

HTML helpers are more lightweight. Unlike Web Form controls, an HTML helper does not have an event model and a view state

For example 

@Html.ActionLink("About this Website", "About")

The Html.ActionLink() helper above, outputs the following HTML:

< a href="/Home/About" > About this Website< / a >

What is KnockoutJS

What is KnockoutJS

Knockout is a standalone JavaScript implementation of the Model-View-ViewModel pattern with templates. The underlying principles are therefore:

A clear separation between domain data, view components and data to be displayed the presence of a clearly defined layer of specialized code to manage the relationships between the view components.

The latter leverages the native event management features of the JavaScript language.

These features streamline and simplify the specification of complex relationships between view components, which in turn make the display more responsive and the user experience richer.

Knockout was developed and is maintained by Steve Sanderson, a Microsoft employee. The author stresses that this is a personal open-source project, and not a Microsoft product

Knockout includes the following features:

Automatic UI refresh (when the data model's state changes, the UI updates automatically)
Dependency tracking
Templating (using a native template engine although other templating engines can be used, such as jquery.tmpl)

Enums in C#

Enums in C#

The enum keyword is used to declare an enumeration, a distinct type that consists of a set of named constants called the enumerator list.
Usually it is best to define an enum directly within a namespace so that all classes in the namespace can access it with equal convenience. However, an enum can also be nested within a class or struct.

By default, the first enumerator has the value 0, and the value of each successive enumerator is increased by 1. For example, in the following enumeration, Sat is 0, Sun is 1, Mon is 2, and so forth.

$( document ).ready() in Jquery

$( document ).ready() in Jquery

$( document ).ready(function() {
    console.log( "ready!" );
});


is equal to

// Shorthand for $( document ).ready()
$(function() {
    console.log( "ready!" );
});


$( document ).ready() will only run once the page Document Object Model (DOM) is ready for JavaScript code to execute. Code included inside $( window ).load(function() { ... }) will run once the entire page (images or iframes), not just the DOM.
