Getting CSS Styles with JavaScript - getComputedStyle() function
 
12:28
In this video we are going to take a look at how to use the window.getComputedStyle() function/method in JavaScript to get the computed CSS styles of an HTML element. Computed Styles are not taken directly from the stylesheet itself but represent the "computed" version of a value. For example, a CSS value of "100%" has a computed value of [number]px.

A Skeptics guide to functional style javascript - Jonathan Mills
 
49:01
With modern JavaScript, we have seen a rise in ‘functional style’ javascript popularity. This style introduces a whole slew of terms and patterns that have different connotations depending on who you are talking to. Phrases like purity, higher order functions, and currying are thrown around all over the place. What does ‘no side effects’ mean, and what about when you need to get something done? And what in the world is a ‘monad’? In this talk, Jon will walk through the world of the functional programmer and show how these phrases and patterns fit into modern JavaScript development. Jon will work through functions as first class objects in JS, and show how we can use that feature to write clean, maintainable, and reusable code. You will also walk away armed with the information you need to see through all they hype. You’ll have a firm grasp of where these patterns are useful, and as importantly, where they are not.

Events in JavaScript
 
17:08
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/2015/01/events-in-javascript.html What is an event An event is a signal from the browser that something has happened. For example, 1. When a user clicks on an HTML element, click event occurs 2. When a user moves the mouse over an HTML element, mouseover event occurs When events occur, we can execute JavaScript code or functions in response to those events. To do this we need to associate JavaScript code or functions to the events. The function that executes in response to an event is called event handler. In JavaScript, there are several ways to associate an event handler to the event 1. Using the attributes of an HTML tag 2. Using DOM object property 3. Using special methods In this video we will discuss associating event handler methods to events using the attributes of HTML tags. In the following example, the code to execute in response to onmouseover & onmouseout events is set directly in the HTML markup. The keyword "this" references the current element. In this example "this" references the button control. [input type="button" value="Click me" id="btn" onmouseover="this.style.background= 'red'; this.style.color = 'yellow'" onmouseout="this.style.background= 'black'; this.style.color = 'white'" /] The above example, can be rewritten as shown below. In this case the code to execute in response to the event is placed inside a function and then the function is associated with the event. [input type="button" value="Click me" id="btn" onmouseover="changeColorOnMouseOver()" onmouseout="changeColorOnMouseOut()" /] [script type="text/javascript"] function changeColorOnMouseOver() { var control = document.getElementById("btn"); control.style.background = 'red'; control.style.color = 'yellow'; } function changeColorOnMouseOut() { var control = document.getElementById("btn"); control.style.background = 'black'; control.style.color = 'white'; } [/script] Events are very useful in real-world applications. For example they can be used to 1. Display confirmation dialog box on submitting a form 2. Form data validation and many more How to show confirmation dialog in JavaScript [input type="submit" value="Submit" id="btn" onclick="return confirmSubmit()" /] [script type="text/javascript"] function confirmSubmit() { if (confirm("Are you sure you want to submit")) { alert("You selected OK"); return true; } else { return false; confirm("You selected cancel"); } } [/script] JavaScript form validation example : In this example, both First Name and Last Name fields are required fields. When you type the first character in any of the textbox, the background colour is automatically changed to green. If you delete all the characters you typed or if you leave the textbox without entering any characters the background colour changes to red indicating the field is required. We made this possible using onkeyup and onblur events. onkeyup occurs when the user releases a key. onblur occurs when an element loses focus. [table] [tr] [td] First Name [/td] [td] [input type="text" id="txtFirstName" onkeyup="validateRequiredField('txtFirstName')" onblur="validateRequiredField('txtFirstName')"/] [/td] [/tr] [tr] [td] Last Name [/td] [td] [input type="text" id="txtLastName" onkeyup="validateRequiredField('txtLastName')" onblur="validateRequiredField('txtLastName')"/] [/td] [/tr] [/table] [script type="text/javascript"] function validateRequiredField(controlId) { var control = document.getElementById(controlId); control.style.color = 'white'; if (control.value == "") { control.style.background = 'red'; } else { control.style.background = 'green'; } } [/script]

Techsith.com id vs class more of a design related question and its a very important one. Overall you will be using more classes then ids. id: think of element that is unique. there is only one id per element. your html validateor would throw and en error if you do use it which means you will not be reusing the same style anywhere else. all the main containers in your HTMLs you should use id because you are not going to repete them . That doesnt mean that you cant use class there. advantage of using is for is as your main namespace. for css this way you can segregate work so your css doesn't messup. for example #leftContainer .button { color:red} which mean all the botton in the left containers are red. class: you can used them freely. any common styles you can define as class. as you can have multiple classes for the same element. and mix and match of the classes will make your css small . for example you can create two divs with same color but diffrent font sizes. Dont forget the attributes. actually id and class are attributes wich special meaning. and you can create your own custome attributes. like myattr. Platforms like angularjs uses them freely. overall i thin its better to use classes then ids especially when you working in a team envirement where you are responsible for a partial html . using id can be riskier if someone else is using the same id in the other part of the html . in css id has higher priority than class for example .....

When you click on the image thumnail, the respective image should be displayed in the main section of the page. For the purpose of this demo we will be using the images that can be found on any windows machine at the following path. C:\Users\Public\Pictures\Sample Pictures Step 1 : Open Visual Studio and create a new empty asp.net web application project. Name it Demo. Step 2 : Right click on the Project Name in Solution Explorer in Visual Studio and create a new folder with name = Images. Step 3 : Copy images from C:\Users\Public\Pictures\Sample Pictures to Images folder in your project. Step 4 : Right click on the Project Name in Solution Explorer in Visual Studio and add a new HTML Page. It should automatically add HTMLPage1.htm. Step 5 : Copy and paste the following HTML and JavaScript code in HTMLPage1.htm page. [html] [head] [style type="text/css"] .imgStyle { width:100px; height:100px; border:3px solid grey; } [/style] [/head] [body] [img id="mainImage" height="500px" width="540x" src="/Images/Hydrangeas.jpg" style="border:3px solid grey"/] [br /] [div id="divId" onclick="changeImageOnClick(event)"] [img class="imgStyle" src="/Images/Hydrangeas.jpg" /] [img class="imgStyle" src="/Images/Jellyfish.jpg" /] [img class="imgStyle" src="/Images/Koala.jpg" /] [img class="imgStyle" src="/Images/Penguins.jpg" /] [img class="imgStyle" src="/Images/Tulips.jpg" /] [/div] [script type="text/javascript"] var images = document.getElementById("divId").getElementsByTagName("img"); for (var i = 0; i [ images.length; i++) { images[i].onmouseover = function () { this.style.cursor = 'hand'; this.style.borderColor = 'red'; } images[i].onmouseout = function () { this.style.cursor = 'pointer'; this.style.borderColor = 'grey'; } } function changeImageOnClick(event) { event = event || window.event; var targetElement = event.target || event.srcElement; if(targetElement.tagName == "IMG") { mainImage.src = targetElement.getAttribute("src"); } } [/script] [/body] [/html] Finally run the application and test it.

Assigning event handlers in JavaScript using DOM object property
 
10:20
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/2015/01/assigning-event-handlers-in-javascript.html In JavaScript there are several ways to associate an event handler to the event. In Part 36, we discussed, associating event handler methods to events using the attributes of HTML tags. In this video we will discuss using DOM object property to assign event handlers to events. First let us understand, what is DOM DOM stands for Document Object Model. When a browser loads a web page, the browser creates a Document Object Model of that page. The HTML DOM is created as a tree of Objects. Example : [html] [head] [title]My Page Title[/title] [/head] [body] [script type="text/javascript"] [/script] [div] [h1]This is browser DOM[/h1] [/div] [/body] [/html] JavaScript can be used to access and modify these DOM objects and their properties. For example, you can add, modify and remove HTML elements and their attributes. Along the same lines, you can use DOM object properties to assign event handlers to events. We will discuss the DOM object in detail in a later video session. We will continue with the same examples that we worked with in Part 36. Notice that in this case, we are assigning event handlers using the DOM object properties (onmouseover & onmouseout) instead of using the attributes of the HTML tag. We are using this keyword to reference the current HTML element. In this example "this" references the button control. [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onmouseover = changeColorOnMouseOver; document.getElementById("btn").onmouseout = changeColorOnMouseOut; function changeColorOnMouseOver() { this.style.background = 'red'; this.style.color = 'yellow'; } function changeColorOnMouseOut() { this.style.background = 'black'; this.style.color = 'white'; } [/script] The following example is same as the above. In this case we are assigning an anonymous function to onmouseover & onmouseout properties. [input type="button" value="Click me" id="btn" /] [script type="text/javascript"] document.getElementById("btn").onmouseover = function () { this.style.background = 'red'; this.style.color = 'yellow'; } document.getElementById("btn").onmouseout = function () { this.style.background = 'black'; this.style.color = 'white'; } [/script] If an event handler is assigned using both, i.e an HTML attribute and DOM object property, the handler that is assigned using the DOM object property overwrites the one assigned using HTML attribute. Here is an example. [input type="button" value="Click me" id="btn" onclick="clickHandler1()"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler set using HTML attribute"); } function clickHandler2() { alert("Handler set using DOM object property"); } [/script] Using this approach you can only assign one event handler method to a given event. The handler that is assigned last wins. In the following example, Handler2() is assigned after Handler1. So Handler2() owerites Handler1(). [input type="button" value="Click me" id="btn"/] [script type="text/javascript"] document.getElementById("btn").onclick = clickHandler1; document.getElementById("btn").onclick = clickHandler2; function clickHandler1() { alert("Handler 1"); } function clickHandler2() { alert("Handler 2"); } [/script]

Build an Accordion Menu - No Frameworks or Dependencies
 
27:48
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!

There are different styles of programming, some quite closely resemble pure mathematics. Mathematician and Computer Scientist Laurence Day compares two of them. Note: In the Java code the delimiters within the 'for' loop should be semi-colons, not commas. Apologies for the error.
