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]

JavaScript modules, CSS properties and JS code style: #1.21 the latest News (the Good Parts)
 
04:48
Hi! Let's talk today about Native #JavaScript modules, #CSS Properties and #JavaScript #code style. I'm Anatol and you are watching the Good Parts of the #FrontEnd #development. "Native #ECMAScript modules: the new features and differences from #Webpack modules" https://blog.hospodarets.com/native-ecmascript-modules-new-features (https://goo.gl/JEFbty) Serg Hospodarets in his article "Native #ECMAScript modules" invites you to take a look into the practical differences between the #ES modules and classic scripts. He also describes how to detect if the module script is loaded or the error occurred. "#ES7 and ES8 Features" https://node.university/blog/498412/es7-es8 (https://goo.gl/eWkb9G) Have you ever heard about ES8? No? Me neither. However #ES2016 has been released officially and #ES2017 is in line. Over the last three years, #JavaScript has become the most versatile scripting language, but before that nothing happened for many years. Therefore you can familiarize yourself with a brief overview on #ES2016 and #ES2017 features like String padding, Descriptors or #Asynchronous Iteration on #Node University blog. "What #javascript #code style is the most popular" https://hackernoon.com/what-javascript-code-style-is-the-most-popular-5a3f5bec1f6f#.v59l6wrcn (https://goo.gl/O1H5HS) A survey "What #javascript code style is the most popular" by Artem Sapegin has got unexpected results. Frankly speaking, not really, maybe just a little bit. Predictably #AirBnb preset has ranked first, but surprisingly at the top of the league, among #NPM projects you won’t find any lint rule. As for me, the main point here is what we declare and what we actually do in our projects. What’s about you? What code style do you prefer? Leave your comments down below. "Intro to Vue.js: Rendering, Directives, and Events" https://css-tricks.com/intro-to-vue-1-rendering-directives-events/ (https://goo.gl/aKgvha) Sara Drasner posted her own introduction to Vue.js on #CSS-Tricks. It comprises five sections and covers the following topics: Rendering, Components, #Vue command line interface, VueX and Animations. "A Beginner’s Guide to #Webpack 2 and Module Bundling" https://www.sitepoint.com/beginners-guide-to-webpack-2-and-module-bundling/ (https://goo.gl/6TI4st) #Webpack has become one of the most important tools for modern web development and now it has been reached version 2. 2 point 2 actually. In this post on Sitepoint you can read a beginner-friendly #Webpack 2 tutorial showing how to set up and configure #Webpack to transform and bundle all your #frontend assets. "Format console.log with #CSS and String Template Tags" https://egghead.io/lessons/javascript-format-console-log-with-css-and-string-template-tags (https://goo.gl/RkmX0B) Are you normally formatting your console log messages? The Chrome console allows you to format messages using CSS properties. John Lindquist described a simple syntax of formatting logs then refactored code into a template tag function. "Let’s Look at 50+ Interesting CSS Properties & Values" https://css-tricks.com/lets-look-50-interesting-css-properties-values/ (https://goo.gl/eUEvNB) Greg Hovanesyan encourages us to take a look at more than 50 interesting CSS properties and values. And it's not only about Flex boxes and Grid layouts. I found some new solutions to old problems here. You might like to keep it in your bookmarks. If you like this video give it "thumbs up".

JavaScript Tutorial - Attribute vs Property
 
09:31
Every HTML element in the HTML markup is represented by JavaScript DOM object. After HTML parsing each element object is converted to DOM object. Every DOM object is a collection of properties and some properties are directly related to the HTML attribute name-value pair. https://github.com/webtunings https://www.facebook.com/pages/WebTunings/339234242822202 I highly recommend this book for beginners as well as advanced programmers: http://www.amazon.com/gp/product/0596805527/ref=as_li_qf_sp_asin_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0596805527&linkCode=as2&tag=webtuningscom-20

Node.nextElementSibling Property - Javascript DOM
 
06:43
The 'nextElementSibling' read-only property in the Javascript DOM allows you to get the next 'Element' sibling of another Node/Element. This is quite powerful when building UIs and you'll see why in this video. This is opposed to the nextSibling property which gives you the next 'Node' sibling instead - and we see how these differ in this video also. As an added bonus, I've also thrown in a use case for the nextElementSibling property by showing an example of a floating, fixed navigation bar that pushes the initial content below it, down.

ParentNode.children Property - Javascript DOM
 
06:13
You can use the 'children' property on a parent node in Javascript to get a list of HTML elements (the child elements of the parent node). This is a live list, meaning when the children of a parent node changes, you do not need to access the 'children' property again. In this video we see how to use the children property, and how to access individual elements with the 'item' method and also the square bracket syntax.

Where should the script tag be placed in html
 
09:40
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/2014/11/where-should-script-tag-be-placed-in.html In this video we will discuss, where should the script tag be placed in the html. Should it be placed in the body or head section of the page. In general the script tag can be placed either in the head or body section. Let's look at a few examples : Example 1 : Script tag in the head section [html] [head] [script type="text/javascript"] alert("Welcome to JavaScript Tutorial"); [/script] [/head] [body] [form id="form1" runat="server"] [/form] [/body] [/html] Example 2 : Script tag in the body section [html] [head] [/head] [body] [form id="form1" runat="server"] [/form] [script type="text/javascript"] alert("Welcome to JavaScript Tutorial"); [/script] [/body] [/html] In Example 1 we placed the script tag in the head section and in Example 2, we placed it in body section. In both the cases JavaScript works as expected. Example 3 : Sets the background color of the TextBox to red. [html] [head] [/head] [body] [form id="form1" runat="server"] [asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox] [/form] [script type="text/javascript"] document.getElementById("TextBox1").style.backgroundColor = "red"; [/script] [/body] [/html] Example 4 : This is same as Example 3, except we moved the script tag to the head section. In this case the script will not work as expected. Depending on the browser you are using you get one of the following JavaScript error. Firefox - TypeError: document.getElementById(...) is null Chrome - Uncaught TypeError: Cannot read property 'style' of null IE - Unable to get property 'style' of undefined or null reference To see these JavaScript errors press F12 which launches developer tools. F12 works for all the 3 browsers. [html] [head] [script type="text/javascript"] document.getElementById("TextBox1").style.backgroundColor = "red"; [/script] [/head] [body] [form id="form1" runat="server"] [asp:TextBox ID="TextBox1" runat="server"][/asp:TextBox] [/form] [/body] [/html] Why did the JavaScript did not work in this case JavaScript code is present before the textbox control. By the time the JavaScript code is executed, the textbox is still not loaded into browser DOM (Document Object Model). This is the reason JavaScript can't find the textbox and throws a NULL reference error. In Part 6, we discussed that, in general it is a good practice to store JavaScript in an external .js file. So, if the JavaScript is present in an external file and if you are referencing it on a page using [script] element, where should such [script] element be placed. To answer this question, first let's understand what happens when a browser starts loading a web page. 1. The browser starts parsing the HTML 2. When the parser encounters a [script] tag that references an external JavaScript file. The parser stops parsing the HTML and the browser makes a request to download the script file. Until the download is complete, the parser is blocked from parsing the rest of the HTML on the page. 3. When the download is complete, that's when the parser will resume to parse the rest of the HTML. This means the page loading is stopped until all the scripts are loaded which affects user experience. In general, the suggested good practice is to place the [script] tag just before the closing [body] tag, so it doesn't block the HTML parser. However, modern browsers support async and defer attributes on scripts. These attributes tell the browser it's safe to continue parsing while the scripts are being downloaded. But even with these attributes, from a performance standpoint it is still better to place [script] tag just before closing [body] tag. According to HTTP/1.1 specification browsers download no more than two components in parallel. So, if the page has several images to download and if you place [script] tags at the top of the page, the script files start to download first which blocks the images download which adds to the total page load time.
