Javascript - How To Create a Basic Javascript Object and Access Its Properties
 
10:43
an object creates a model by grouping together a set of related variables, values and functions an object's properties can use different value types e.g. string, number, boolean, array and even functions (if a property's value is a function, it is called a method), it can even contain other objects you can access an object's properties using dot notation, most commonly used because it's easier to use and easier on the eyes you can also access an object's properties using bracket notation, although less commonly used, it has a couple of advantages over dot notation -bracket notation is the only way to access property or method names that don't follow variable naming rules (e.g. a property name like "another key" has a space inbetween) -with bracket notation you can also access an object's property using string concatenation, although not entirely recommended if you try to access a property that doesn't exist, undefined will be returned - https://youtu.be/D2E-mxbjBrw - Javascript - How to Access Javascript Object Property Names Using Object.keys() - https://youtu.be/fDBuAnu0fvo - Javascript - How to Access Javascript Object Property Names Using A for in LOOP ---------------- resources: http://stackoverflow.com/questions/4968406/javascript-property-access-dot-notation-vs-brackets ----------------------------------------------------------- http://atechapart.com | http://linkedin.com/in/alvinsanchez see my codepens @ http://codepen.io/_asanchez/

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 Tutorial - Attribute vs Property

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

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 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]

React Fundamentals: Introduction to Properties
 
02:45
This lesson will teach you the basics of setting properties in your React components. Transcript So the purposes of this lesson, we're going to strip our main JS down to just import app from app, since we're going to be doing our rendering directly from our app.js. We can pass values into our component using something called props or properties, this is going to look a lot like passing in attribute or setting an attribute on a standard HTML element. So here I've got an attribute or a prop called text, I'm going to pass in, "This is the props text." Now the way we access that from within our component is by interpolating this value with curly brackets, and we say this.props. whatever the name of the prop is, so in our case it's txt for text, we'll save that, on the right here we get our, "This is the props text." Now outside of JSX we don't need to interpolate that, so I'm going to set a variable here called text to this.props.text and we'll go ahead and use that in our JSX, that's just text. I'm going to go ahead and update this to value just so we can see it happen on the page. Now we've got our, "This is the props value." We can also define the property types that we're expecting by adding a property to our component called proptypes, and that's just going to be an object where each key of the object is the name of our property, and then we pass in the type from React that we're expecting. So in this case, React.proptypes.string means we are expecting a string here. I'm going to create one more called cat, and that's going to be a React proptype of number. When I save this, this is going to work just fine. However, on any of these proptypes we can tack on isRequired. Sorry, that should be a capital R, isRequired defines that this is a required property. So if I save this, we're going to get an error here that the required prop of cat was not specified in app. So here in our app component, I'm going to say cat = 5, save that, and now everything's working as we expected. We can also define default properties, again by setting a property on our class component here it's going to be default.props again it's going to be an object and it follows basically the same pattern. The key is the name of our property and then the value that follows that is the default value for that prop. So I'll this is the default text here, going to save that, and on the right what you'll see is that the property that we passed in is actually overriding that, so if we save it, we should get our default property value.

Core Javascript Tutorial -Expressions - How to create object using new
 
07:50
Object can be created by object literal or using new operator. For example new Date() is an object creation expression that creates Date object or instance of Date class. As you know every expression should produce some value. Here object creation expression using new operator creates a new object. new Date(2012,1,1) evaluation process: -Creates an empty object -It calls associated Date constructor function that initializes all properties. Constructor function sets values of all properties. Here it's setting year, date and month. Generally constructor function doesn't return anything explicitly. Constructor function creates a new object. If return value is defined inside the constructor function, newly created object will be discarded.

How Javascript Inheritance Works
 
02:37
Do you know how Javascript inheritance works? Property inheritance only occurs if you read property values, but it does not happen if you specifically write the value of the property. So it is kind of like a will where your kids automatically get half unless you specifically say they get X or Y. Inheritance in JavaScript is when something inherits its properties from another type. JavaScript inheritance is done with prototypes instead of Java's class based inheritances. I've heard horror stories about Java classes, both in the classroom and while coding. Only functions can have a prototype. This is why you create functions before you worry about their inheritances. Just like you have to have heirs before you worry about a will. You use the prototype object in JavaScript to assign properties to different types. The attributes and behavior defined on the parent are then accessed by the child created from each type. It is like a subset in a Venn diagram. That sounds simpler than Java classes. You can set up class based inheritance in JavaScript using ECMA Script standards. Action Script supports classes, too. That's way beyond me at this point. Constructors give the name for the class of objects and will initialize their properties. What do constructors build? The prototype objects are associated with the constructor. Every object initialized by the constructor gets the same set of properties from the prototype object associated with the constructor. But you can have multiple objects associated with one prototype. Inheritance is a result of looking up the property value of the properties and attributes of the parent object. You can use prototype inheritance without constructors, if you create a new object with a specified prototype that inherits the new item. That's getting complicated. You can compare JavaScript inheritance to extensions, where the child extends a parent with additional members or rules. OK. Prototype objects hold methods and properties, and they should be shared by each instance. Types inherit the prototype properties. And that's the JavaScript inheritance law. But anything more complicated, and I need an attorney. No, just a good JavaScript tutorial.

ZIM Bubbling: 71. Style for Canvas 2 - for ZIM at http://zimjs.com/ The latest updates for the ZIMjs Framework - Complete Canvas Coding and Creation. NEW IN ZIM OCT (8) https://zimjs.com - come on in and discuss https://zimjs.com/slack STYLE can be used to set any parameter on a DisplayObject. For instance: Circle, Blob, Button, Pane, Bitmap, Sprite, etc. These are applied at the time the objects are made. They are cascading with each level overriding the previous level: 1. GENERAL: any style can be specified in general corner:30 will make all corners default to 30 2. TYPE: styles for object type can be set to override the general styles Button:{corner:0} will make all button corners default to 0 3. GROUP: styles for a group can be set to override the type styles homePage:{corner:20} will make all objects of that group default to 20 4. OBJECT: styles applied as parameters to the object override all other styles new Button({corner:40}) will make this button have a corner of 40 TRANSFORM STYLES Transformations can also be applied (all are numbers - visible is a Boolean): x, y, rotation, alpha, scale, scaleX, scaleY, regX, regY, skewX, skewY, visible a bounds style has a value of {x:Number, y:Number, width:Number, height:Number} where x and y are optional RANDOM, RANGES, SERIES, FUNCTIONS Any property value can be a ZIM VEE value to make use of ZIM zik (pick) color:[red, green, blue] will pick a random color for each object for which the style is applied x:series([100,200,300]) will place subsequent objects at these locations width:{min:100, max:500} will make objects with a width within this range See Docs on ZIM zik() and ZIM series() for more information FUNCTION STYLES The following functions have been added: addTo, center, centerReg, transform, drag, gesture, outline, mov, animate, wiggle Values of true will give default functionality for all but mov, animate and wiggle ZIM DUO configuration objects can be set as a value for any of these example: drag:true; or drag:{onTop:false} For animate and wiggle, [] can be put around multiple configuration objects to wiggle in the x and y for instance or run multiple animate calls on the object CONVENIENCE STYLES add:true - has been provided to add to the stage (use addTo for other containers) move:{x:value, y:value} or move:x - mirrors the mov Function style (just adding the e) style:false - will turn off all styles for the selector EXCLUSION A value of ignore can be used to exclude any earlier styles and return to the original default. ignore is a ZIM global variable - if zns is true then use zim.ignore or just "ignore". Setting style:false will exclude the object from all styles All DisplayObjects have a style parameter (default true). Set to false to ignore styles. GROUPS All DisplayObjects have a group parameter. This parameter accepts a string or a comma delimited string of multiple groups. The group of components can then be targeted in the Group section of STYLE. A group can contain just one component and act like an ID in CSS.

I set the property weightCategory but if I do this, it will also modify the objects in the original array because objects are passed by reference in javascript. The objective of the map and filter methods are to create new arrays, not to modify the original so, we could've created a variable with an object that only consisted of the name and the weight category of the person, then return it.

Angular select options from array

Step 1 : Create the Department class. Add a TypeScript file to the models folder. Name it department.model.ts. Copy and paste the following code. Notice the Department class has 2 properties - id and name of the department. export class Department { id: number; name: string; } Step 2 : Import the Department class. Include the following import statement in create-employee.component.ts file import { Department } from '../models/department.model'; Step 3 : Include the following array of departments in CreateEmployeeComponent class in create-employee.component.ts file departments: Department[] = [ { id: 1, name: 'Help Desk' }, { id: 2, name: 'HR' }, { id: 3, name: 'IT' }, { id: 4, name: 'Payroll' } ]; Please note : The "Department" type is not required for the application to work, but it adds great value during development. Using it provides us intellisense, error checking and type saftey. For the HTML used in the video, please refer to my blog link below http://csharp-video-tutorials.blogspot.com/2018/01/angular-select-options-from-array.html Code explanation: 1. On the "option" element we are using ngFor structural directive to loop over the array of departments we have in the "departments" property of the component class 2. For each "Department" object in the "departments" array, we get an option. 3. The option value is the department id and the display text is the department name 4. Notice the square brackets around the [value] property. This is property binding in Angular. We discussed property binding in detail in Part 9 of Angular 2 tutorial. If you remove the square brackets the value for each option will be the literal text "dept.id" instead of the department id (1 or 2 or 3 etc.) Property binding in Angular https://www.youtube.com/watch?v=RGYfTx9AAQA&list=PL6n9fhu94yhWqGD8BuKuX-VTKqlNBj-m6&index=9 5. To display the deprtment name we are using interpolation. We discussed interpolation in Part 8 of Angular 2 tutorial. Interpolation in Angular https://www.youtube.com/watch?v=2FkkAqFWRk8&list=PL6n9fhu94yhWqGD8BuKuX-VTKqlNBj-m6&index=8 6. Since ngFor is a structural directive there is an asterisk before it. 7. Structural directives modify the DOM, i.e they add or remove the elements from DOM. Adding and removing elements from DOM is different from showing and hiding. We will discuss all these in detail in our upcoming videos. At this point, when we select a department, the respective department id is included in the Angular generated form model. Along the same lines, when we click the "Save" button the respective department id is logged to the console. Please note : It is important that we include the ngFor directive on the element that we want to be repeated. In our case we want an option element for each department we have in the array. So we included the ngFor directive on the option element. If we instead include the ngFor directive on the "div" element that has the bootstrap "form-group" class, we get 4 department dropdownlists. That is one for each department in the array. So it is important we include the ngFor directive on the right element.

Javascript Scroll Tutorial Load Dynamic Content Into Page When User Reaches Bottom Ajax
 
15:18
Lesson Code: http://www.developphp.com/video/JavaScript/Scroll-Load-Dynamic-Content-When-User-Reach-Bottom-Ajax Learn to make dynamic page content appear only when user scrolls down to the bottom of your page content using Javascript. We are using the onscroll event for the window object and several DOM properties to create the functionality. *object.offsetHeight - *window.pageYOffset - *window.innerHeight. It serves as a smart way for dynamic websites to load only the data required to fill the window, then load more as the user scrolls down the page. You can see this effect if you have a Facebook account and you scroll down your timeline. Facebook executes new Ajax requests each time you scroll to the bottom of the page content, to load in more data to the page magically with Ajax. This way they do not have to load a lot of data to the page initially, and only spend dynamic data loading energy if the user scrolls down the page to see more and more data. Other large scale dynamic websites also use this approach to achieve efficient database data rendering in a smart modern way.
