JavaScript for Web Designers
In this course you’re going to learn the basics of JavaScript from a web designer’s perspective. We’ll begin by going over the basics, such as JavaScript variables, data types, and loops, before working toward more complex notions such as functions, selectors, and events. Along the way, we’ll build some examples that are geared towards what you as a web designer might face on a daily basis. If this course inspires you to learn JavaScript for web development, check out our comprehensive guide: https://code.tutsplus.com/series/learn-javascript-the-complete-guide--cms-1112?ec_promo=tuts_youtube&ec_unit=description&ec_topic=webdesign Chapters 0:00 Introduction: JavaScript for Web Designers 0:27 1. Working With JavaScript If you’re not yet familiar with JavaScript, let’s run through a quick intro. 4:54 2. Variables If you’ve ever used a CSS preprocessor like LESS or Sass then you’re already familiar with the concept of “variables”. Variables are used to store data in a specific format. They can contain numbers, strings of characters, and so on. 9:07 3. Data Types In this lesson, you’ll learn about the available “data types” in JavaScript. 13:17 4. Arrays Let’s learn about the first “composite” data type in JavaScript: arrays. 20:04 5. Objects Understanding “objects” in JavaScript starts with an understanding of “properties”. Here you’ll learn about both of these concepts. 25:25 6. Operators Let’s learn about operators and the various types thereof. We’ll begin with “arithmetic” operators. 34:07 7. If Else Statements Let’s now look at the if/else statement. If you know any other programming language then you’ll already be familiar with the concept of conditional statements. If not, don’t worry—we’ll cover all of that. 38:50 8. Loops A loop is a piece of code that executes repeatedly, either a set number of times or until a certain condition is met. Let’s see how we can loop in JavaScript. 45:01 9. Functions You can think of functions as being “subprograms” which can have their own name, can be called anytime, can receive parameters, and can return a value. 51:17 10. Selectors Selectors are great if you want to manipulate the DOM and gain access to all its elements. To understand selectors, first let’s have a look at the window and document objects. 59:17 11. Events The term “JavaScript events” is perhaps a bit improper because the events are actually happening on the HTML side. All you can do in JS is listen to these events and react accordingly. 1:06:15 12. Back to Top Button Having covered a great deal of theory, let’s now practice what we’ve learned with some exercises. To begin with, let’s see how we can create a “back to top” button. 1:17:11 13. Textbox Auto Completion You’ll learn how to create a textbox that supports auto-completion. 1:31:42 14. Simple Content Slider In this practical exercise, let’s create a simple content slider. We’re not going to limit ourselves to images either; we’ll create a slider that can display any type of content. 1:39:50 15. Image Lightbox In this exercise we’ll create a very simple image lightbox. A lightbox is usually an overlay that shows a much bigger version of a thumbnail. 1:44:02 16. Tab Control The “tab control” is a very common pattern, so let’s see how it’s done in this final exercise lesson. 1:46:43 17. Final Words Hopefully by now you’ll have a better understanding of what you can do with JavaScript from a web design point of view.

Javascript Events Tutorial - How Web Developers Respond to User Input
Simple Javascript Events Tutorial with code! Almost every Web Developer finds themselves needing to respond to user actions on a page by changing content or adjusting the page display somehow. The way you do that is by listening to Javascript events. VIEW THE CODE: - addition: http://codepen.io/anon/pen/vOeeqG?editors=101 - pic link: http://codepen.io/anon/pen/vxYxKN?editors=101 Popular Javascript Events Are: - click - mouseenter - mouseleave - mousedown - mouseup - mousemove - keydown - keyup - blur - focus See list of all javascript events here: https://developer.mozilla.org/en-US/docs/Web/Events In this lesson, we'll add event listeners to html elements. When the users click, focus, blur, press a key, or move their mouse, javascript will get notified and we can make the webpage change. Listening to Javascript events is a bread and butter task for web development and web developers. -~-~~-~~~-~~-~- Learning Web Development?

How To Write Secure JavaScript Applications
Thought you knew JavaScript security? Well, you don't. At least not as well as you thought you did. From CSRF to crypto, I'm going to teach you everything you absolutely must know to write secure JavaScript, especially web applications in particular, both front and backend. An emphasis will be put on teaching *practical* techniques and *best practices* that you can immediately go back to your company or organization and implement. Among the topics we will cover are preventing common and not-so-common but still critical vulnerabilities in JavaScript code, ranging from CSRF, command injection, improper password handling, broken authentication and authorization, bad cryptography, and more. We will also cover the best practices when attempting to write secure JavaScript code, on both the front and backend. From things like properly implementing user management schemes to as high-level as convincing your co-workers that security *does matter*, we will explore as much as possible in the time we have together. Best of all, you *don't have to have security experience*! Come as you are and dive into the intertwined worlds of JavaScript and security and learn how to write the most secure JavaScript and Node.JS applications of your life.

JavaScript array filter method
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/12/javascript-array-filter-method.html The filter() method creates a new array and populates that array with all the elements that meet the condition specified in a callback function. Syntax : array.filter(callbackFunction[, thisArg]) Parameters callbackFunction Required. Function that gets called for each element of the array. If the function returns true, the element is kept otherwise filtered. thisArg Optional. An object to which the this keyword can refer in the callbackfn function. The filter method calls the callbackfn function one time for each element in the array. If the callback function returns false for all elements of the array, the length of the new array that will be returned is 0. Callback Function Syntax function callbackFunction(value, index, array) Callback Function Parameters value The value of the element in the array index The index position of the element in the array array The source array object that contains the element Example 1 : Retrieve only even numbers from myArray // Callback function function IsEven(value, index, array) { if (value % 2 == 0) { return true; } else { return false; } } // Source array var myArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; // Pass the callback function as argument to the filter method var result = myArray.filter(IsEven); document.write(result); Output : 2,4,6,8,10 Example 2 : In Example 1 we defined a callback function first and then passed it as an argument to the filter() method. In the example below, we created the callback function as an anonymous function directly in the filter method where it is required. // Source array var myArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; // callback function created directly in the filter method as anonymous function var result = myArray.filter(function (v, i, a) { return v % 2 == 0 }); document.write(result); Output : 2,4,6,8,10 Example 3 : Remove duplicates from javascript array var myArray = ["Sam", "Mark", "Tim", "Sam"]; var uniqueItems = myArray.filter(function (v, i, a) { return a.indexOf(v) == i }); document.write(uniqueItems); Output : Sam,Mark,Tim

What is Node.js Exactly? - a beginners introduction to Nodejs
What exactly is node.js? Is it a command-line tool, a language, the same thing as Ruby on Rails, a cure for cancer? If you're new to web development, it can be a bit confusing as to what exactly node.js is and to what you should do with it, and there's a lot of information out there...most of which seems to be tailored towards genius-level developers. So, here's a node.js introduction for those who have no idea what it is. We're going to cover the difference between javascript in a browser vs javascript in node.js and the common uses for node.js. To wrap it up, we're going to spin up a quick web server in node.js just to show you how easy it is.

JavaScript Cookies
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2015/02/javascript-cookies.html In this video we will discuss 1. What are cookies and why are they needed 2. How to write a cookie and read it later Why are cookies needed Web applications work on HTTP protocol which is a stateless protocol. This means after the web server has processed the client request for a web page, the web server will not remember anything about the client that made the request. Let us understand what this statement means with an example. 1. Design a web page with a DropDownList. 2. When the user selects a color from the DropDownList we want to change the background color of the page to the selected color. 3. We want the web application to remember the user's preferred color. On a subsequent visit to the same page it should display the page with the background color that we previously selected. 4. Now close the browser. Open a new instance of the browser and navigate to the same page. Notice that, the page does not remember the color we selected earlier. This is because web applications work on HTTP protocol which is a stateless protocol. This means after the web server has processed the initial client request, it does not remember aynthing about the settings the client made. There are several ways to make a web application remember these settings. One of the easiest and common ways is by using cookies. What are cookies Cookies are small text files that a browser stores in the visitor's computer. A cookie is basically a string of name-value pairs separated by semi-colons. How does a cookie look color=red;expires=Fri, 5 Aug 2016 01:00:00 UTC; In the cookie string above we have 2 name-value pairs. The expires attribute specifies when the cookie is going to expire. By default cookies are deleted when the current browser session ends. If you want to store the cookie on the client computer even after the browser session has ended then specify either expires or max-age attributes. The color attribute is set to "red". How to write a cookie : Use the document object's cookie property to write the cookie. document.cookie = "color=red;expires=Fri, 5 Aug 2016 01:00:00 UTC;" How to read a cookie : Use the document object's cookie property to read the cookie. var cookieString = document.cookie; Here is the complete example which remembers the user color preference [select id="ddlTheme" onchange="setColorCookie()"] [option value="Select Color"]Select Color[/option] [option value="red"]Red[/option] [option value="green"]Green[/option] [option value="blue"]Blue[/option] [/select] [script type="text/javascript"] window.onload = function () { if (document.cookie.length != 0) { var nameValueArray = document.cookie.split("="); document.getElementById("ddlTheme").value = nameValueArray[1]; document.bgColor = nameValueArray[1]; } } function setColorCookie() { var selectedValue = document.getElementById("ddlTheme").value; if (selectedValue != "Select Color") { document.bgColor = selectedValue; document.cookie = "color=" + selectedValue + ";expires=Fri, 5 Aug 2016 01:00:00 UTC;"; } } [/script]

Build an Accordion Menu - No Frameworks or Dependencies
Increasingly, I am noticing how many new developers haven't learned the core essentials to building common web elements such as modals, menus, accordians, tabs and so forth, without the help of a framework. This video will teach you how to build an accordian menu without using an dependencies or frameworks. We will use some basic HTML, CSS, and JS. No dependencies are used in this tutorial. No jQuery or Vue or Angular or React. We write it all by scratch and we make sure you understand why each line of code exists. This is a basic accordion menu like those you often find on Frequently asked questions pages. It is surprisingly easy to build. We will start by building a basic menu, and then enhancing it with a few animations and icons to further enhance its interactive elements. ==== DOWNLOAD SOURCE CODE ==== GitHub Repo (Star, Watch and Fork): https://github.com/DevMarketer/NoFrameworks Download Code from this Episode: https://github.com/DevMarketer/NoFrameworks/releases/tag/accordions ==== FOLLOW ME ==== Subscribe for New Releases!

Real-Time Machine Learning with Node.js by Philipp Burckhardt, Carnegie Mellon University
Real-Time Machine Learning with Node.js - Philipp Burckhardt, Carnegie Mellon University Real-time machine learning provides statistical methods to obtain actionable, immediate insights in settings where data becomes available in sequential order. After providing an overview of state of the art real-time machine learning algorithms, we discuss how these algorithms can be leveraged from within a Node.js application. We will see why the powerful API of the core stream module makes Node.js a more attractive platform for such tasks compared to languages traditionally used for scientific computing such as R, Python or Julia. Finally, we will discuss best-practices and common pitfalls that one faces when using these algorithms.

Part 6   Calling asp net web service from javascript using ajax
Link for code samples used in the demo http://csharp-video-tutorials.blogspot.com/2013/11/part-6-calling-aspnet-web-service-from.html Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists In this video, we will discuss calling asp.net web service method from javascript using asp.net ajax. This is what we want to achieve. Once we type student ID in the textbox and when we click "Get Student" button we want to 1. Invoke StudentWebService from javascript using asp.net AJAX 2. The student web service should return the specific student data from a database table. 3. The returned data should be displayed in the respective textbox controls on the web form. Steps to call a web service from JavaScript using ASP.NET AJAX 1. Decorate web service class must with [System.Web.Script.Services.ScriptService] 2. Include ScriptManager control on the WebForm from where you want to call the web service and specify the path of the web service. 3. Implement JavaScript function to call the Web Service. Could you explain how an object-oriented application such as ASP.NET web application can make use of web services to access a relational database ? In this video, we discussed exactly the same thing. ASP.NET Web application calls the web service, and the web service has ado.net code to retrieve data from a relational database. Just like an asp.net web application, a web service can work with any type of datastore (Relational databases, xml file, text file, access, excel etc) Where does ADO.NET and XML webservices come in architecture? Most of the real time applications have 3 or more layers. The most common layers in many of the applications are as follows 1. User Interface of Presentation Layer - Contains only the UI logic 2. Business Logic Layer - Contains logic to validate business rules 3. Data Access Layer - Performs the database CRUD operations With respect to the above architecture Web services belong to Business Logic Layer ADO.NET belong to Data Access Layer How to call a webservice from the web form without reloading the entire web page. OR How to call a webservice without full page postback Call the web service using ASP.NET AJAX, which allows partial page postback. With partial page postback, only specific portion of the page is updated without reloading the entire page which is better for performance and avoids screen flickers.

Gulp.js Build System #1 - Fundamentals
In part one of this three part series we will look at the fundamental concepts behind creating a Gulp.js front-end build system. PLAYLIST: https://www.youtube.com/watch?v=LmdT2zhFmn4&list=PLv1YUP7gO_viROuRcGsDCNM-FUVgMYb_G BLOG POST: http://joellongie.com/gulp-build-system-fundamentals/ Subscribe and Get More Great Tips! http://www.youtube.com/subscription_center?add_user=joellongie Check me out around the web: ----------------------------------------­-------------------- Blog: http://joellongie.com Twitter: https://twitter.com/joellongie Google+: https://plus.google.com/+joellongie ----------------------------------------­-------------------- Description ----------------------------------------­-------------------- If in the past you have ever been intimidated or confused trying to set up a front-end build system you are not alone. A few years ago I had my first introduction to the process watching a video series on YouTube about Grunt. At the time I diligently followed the videos and within a few hours had my first working Grunt setup, well sort of. It functioned as advertised, but to be honest I had no real understanding of how all the Grunt syntax worked, or how all the parts fit together. If like me you have been scratching your head trying to make sense of it all then keep reading. This post will help give you an overview and provide a scaffolding to help demystify some of these moving parts as well as looking at a simpler, faster replacement for Grunt. What Is A Build System, gulp.js A build system like gulp is simply a collection of tasks (commonly called “task runners”) that automate repetitive work. Typical usage would include compiling preprocessed CSS and JavaScript, concatenation, minification, firing up a server for automatic browser reloading and creating a deployment build. Build systems usually work in tandem with other tools like package managers. While there are literally countless ways to configure your build system lets take a look at three of the most common components in a typical front-end workflow. 1. Package Managers Package managers are tools that are used to automate the installation, upgrading, removal, and dependencies for the packages and libraries used in your dev environment. We will be using both Bower and NPM (Node Package Manager) in our upcoming gulp workflow. If it seems redundant to use two package managers instead of just picking one or the other I completely appreciate where you are coming from. It took me quite a bit of research before I started to understand the subtle distinction between the two. While both manage dependencies, their intended target environments are different. As you can see in the diagram above, Bower manages our gulp front-end dependencies while NPM is used to manage dependencies within the Node.js environment. If this still seems a little confusing then look at it like this: Bower is used to manage libraries like jQuery, Backbone, or RequireJS that affect your actual project files. NPM on the other hand handles utility modules that work with node to assist in your build process. This explanation is of course a gross oversimplification. Both Bower and NPM have many overlapping responsibilities and in some cases the line might be blurred. Though their might be some grey areas to deal with, in general, understanding the intent of both package managers will help clarify which dependencies go where. 2. Preprocessors Preprocessors are critical to an efficient modern workflow by adding additional features and an optimized syntax that compiles into its native language. Some of the most popular preprocessors used for CSS, JavaScript and HTML include: CSS: Sass, Less, Stylus JavaScript: CoffeeScript, Typescript HTML: HAML, Jade, Markdown, Slim While most preprocessors can be used independent of build tools like Gulp or Grunt, pairing your preprocessors with your build tools gains you both efficiency and enhanced functionality. For example, watch tasks are frequently created to watch for file changes and then update the browser. We will look at this much more in detail in part three of this series. 3. Gulp Task Based Build Tools Now lets get to the meat of it, Gulp and Grunt. Both run on Node, both are great tools, and both share a similar anatomy. Although we will be using Gulp in this series, Grunt follows the same overall structure. We will be getting into a few of the core differences between Grunt and Gulp in the next section, but for now lets take a look at the structure of a typical gulp file. Starting at the top and moving down, the first step is to declare which modules will be required by Gulp. This is where we declare both gulp itself as well as all the dependencies we need for our build. Finish reading this post at: http://joellongie.com/gulp-build-system-fundamentals/
