Fat Arrow Functions JavaScript Programming Tutorial
 
12:36
Lesson Code: http://www.developphp.com/video/JavaScript/Fat-Arrow-Functions-JavaScript-Programming-Tutorial Crash course on using the new Arrow functions in JavaScript, introduced in ECMAscript Edition 6 to provide a new approach to writing anonymous functions. Arrow functions have 2 major advantages over traditional anonymous functions. (a) They reduce the amount of code you need to write. (b) In object oriented programming, the "this" keyword always refers to the object no matter how many anonymous functions are nested in the class. We will demonstrate these concepts through code right now starting with the most basic. They are Anonymous functions. Anonymous functions are functions that have no name like normal functions do. We see them used as parameters in methods that expect exectuable code as an argument. Anonymous functions are used in object oriented programming, or they are sometimes supplied as the value of a named variable. We will compare traditional Anonymous function syntax with arrow function syntax side by side using several simple examples in order to demonstrate where, when and how to use arrow functions where you normally use anonymous functions.

The Object.assign() Method in JavaScript - Set default options for functions
 
10:06
The assign() method on the Object constructor in JavaScript is used to merge multiple objects together. You can use it to merge as many objects as you like. If multiple objects have the same property, the "merged object" will also contain that property but the value of it will come from the last object passed in as an argument. This means it can be used to easily create "default options" within a function. In this video I take you through examples of how you can use the Object.assign() method and also an example of using it to create default options in a function.

JavaScript Function Default Parameters
 
04:23
New in the ES6 version of JavaScript are default function parameter values. This is something that has existed in other programming languages for quite a while but is new to JavaScript. We can now create optional parameters for function arguments. We always had the ability to declare a long list of parameters in a function declaration and the function would run even when those parameters were not provided in the call to the function. The downside was that all the unprovided parameters had a value of undefined. Now we can provide a default value for any parameter, which means that we truly have optional parameters for functions. REMEMBER: always put your optional values at the end of your list. JavaScript won't know if you meant to skip over a value. The default values should be last and the required values should come first. Code GIST: https://gist.github.com/prof3ssorSt3v3/9ee7efa0d5b7f8ef4cd9f4c9c8c3d817

The multidimensional array tutorial from yesterday is going to come into play within this application build. You can easily add a timer with setInterval(), and apply all the bells and whistles you need using JavaScript. Storing the questions/answers/options in a secure database that PHP can access, is the most practical way to make sure people do not cheat when you need the test to be secure and cheat proof. Ajax requests would be a big part of that interaction with the server. I discuss securing and externalizing the test data more in the video.

Functions in JavaScript

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/functions-in-javascript.html A function is a block of reusable code. A function allows us to write code once and use it as many times as we want just by calling the function. JavaScript function syntax function functionName(parameter1, parameter2,..parameter_n) { //function statements } Points to remember 1. Use the function keyword to define a function, followed by the name of the function. The name of the function should be followed by parentheses (). 2. Function parameters are optional. The parameter names must be with in parentheses separated by commas. Example : JavaScript function to add 2 numbers. The following JavaScript function adds 2 numbers and return the sum function addNumbers(firstNumber, secondNumber) { var result = firstNumber + secondNumber; return result; } Calling the JavaScript function : Call the JavaScript function by specifying the name of the function and values for the parameters if any. var sum = addNumbers(10, 20); alert(sum); Output : 30 What happens when you do not specify values for the function parameters when calling the function The parameters that are missing values are set to undefined Example : In the example below, we are passing 10 for the firstNumber parameter but the secondNumber parameter is missing a value, so this parameter will be set to undefined. When a plus (+) operator is applied between 10 and undefined we get not a number (NaN) and that will be alerted. function addNumbers(firstNumber, secondNumber) { var result = firstNumber + secondNumber; return result; } var sum = addNumbers(10); alert(sum); Output : NaN What happens when you specify too many parameter values when calling the function. The extra parameter values are ignored. Example : In the example below, 30 & 40 are ignored. function addNumbers(firstNumber, secondNumber) { var result = firstNumber + secondNumber; return result; } var sum = addNumbers(10, 20, 30, 40); alert(sum); Should a javascript function always return a value No, they don't have to. It totally depends on what you want the function to do. If an explicit return is omitted, undefined is returned automatically. Let's understand this with an example. The following function returns the sum of two numbers. We are storing the return value of the function in sum variable and writing it's value to the document. function addNumbers(firstNumber, secondNumber) { var result = firstNumber + secondNumber; return result; } var sum = addNumbers(10, 20); document.write(sum); The following function does not return any value. It simply writes the sum of two numbers to the page. However, we are assigning the return value of addNumbers() function to sum variable. Since addNumbers() function in this case does not have an explicit return statement, undefined will be returned. function addNumbers(firstNumber, secondNumber) { var result = firstNumber + secondNumber; document.write(result); } var sum = addNumbers(10, 20); alert(sum);

JavaScript Cookies
 
12:06
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]
