Learning Knockout Js

Knockout JS

Knockout is a JavaScript library that helps you to create rich, responsive display and editor user interfaces with a clean underlying data model.

Knockout js is client side only it simplifies the html (or view) and java script (or model) to make a more manageable and dynamic web interface. 

My first project with knockout js

// HTML

<p>First name: <input data-bind="value: firstName" /></p>

<p>Last name: <input data-bind="value: lastName" /></p>

<h2>Hello, <span data-bind="text: fullName"> </span>!</h2>




// JavaScript Code

var ViewModel = function(first, last) {

    this.firstName = ko.observable(first);

    this.lastName = ko.observable(last);

 

    this.fullName = ko.pureComputed(function() {

        

        return this.firstName() + " " + this.lastName();

    }, this);

};

 

ko.applyBindings(new ViewModel("Planet", "Earth"));
