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.

This is continuation to Part 69. Please watch Part 69 before proceeding. When we click "Set Cookie" button we want to store the following 3 key-value pairs in 3 cookies. name=Venkat; [email protected]; gender=Male; When we click "Get Cookie" button we want to retrieve all the 3 key-value pairs from the 3 cookies Modify the code in setCookie() function as shown below. function setCookie() { document.cookie = "name=" + document.getElementById("txtName").value; document.cookie = "email=" + document.getElementById("txtEmail").value; document.cookie = "gender=" + document.getElementById("txtGender").value; } The above code creates 3 cookies and stores the 3 key-value pairs. At this point document.cookie property contains the following string "name=Venkat; [email protected]; gender=Male" Now, modify the code in getCookie() function as shown below. function getCookie() { if (document.cookie.length != 0) { var cookiesArray = document.cookie.split("; "); for (var i = 0; i [ cookiesArray.length; i++) { var nameValueArray = cookiesArray[i].split("="); if (nameValueArray[0] == "name") { document.getElementById("txtName").value = nameValueArray[1]; } else if (nameValueArray[0] == "email") { document.getElementById("txtEmail").value = nameValueArray[1]; } else if (nameValueArray[0] == "gender") { document.getElementById("txtGender").value = nameValueArray[1]; } } } else { alert("No cookies found"); } }

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.

Reflect construct, data and accessor properties in ES6
 
12:48
Reflect.construct Reflect.construct is Used to invoke functions as constructors This function is called the Target constructor Reflect.construct takes in 3 arguments ie. The target constructor, arguments of the target constructor and another constructor whose prototype is used as the prototype of the target constructor Property Descriptors Property descriptors in objects are of two types: data descriptor and accessor descriptor Data descriptor is a property that has a value, which may or may not be writable Accessor descriptor is a property described by a getter setter pair of functions Descriptors can either be data or accessor but not both Data and Accessor Descriptors Data and Accessor desciptors are objects Following keys are common in both: - Configurable: true if and only if the type of this property descriptor may be changed and if the property may be deleted from the corresponding object. Defaults to false - Enumerable: true if and only if this property shows up during enumeration of the properties on the corresponding object. Defaults to false Keys optional to data descriptors Data descriptors have the following optional keys value: The value associated with the property. Can be any valid JavaScript value (number, object, function, etc). Defaults to undefined. Writable: true if and only if the value associated with the property may be changed with an assignment operator. Defaults to false. Keys optional to Accessor Descriptors get: A function which serves as a getter for the property, or undefined if there is no getter. When the property is accessed, this function is called without arguments and with this set to the object through which the property is accessed (this may not be the object on which the property is defined due to inheritance). The return value will be used as the value of the property. Defauls to undefined. set: A function which serves as a setter for the property, or undefined if there is no setter. When the property is assigned to, this function is called with one argument (the value being assigned to the property) and with this set to the object through which the property is assigned. Defaults to undefined

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/

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.

attributes property is defined on the Element interface.

Javascript Tutorial | Create & Append DOM Element's
 
12:55
In this lecture I'll be making a virtual DOM object within Javascript. Then I'll tell the DOM to add the relevant element using the information from our virtual DOM object. This will allow me to produce an element from Javascript. This tutorial is brought to you by http://www.avelx.co.uk/ - Coding tutorials to help you grow.

Angular select options from array

Text version of the video http://csharp-video-tutorials.blogspot.com/2018/01/angular-select-options-from-array.html Slides http://csharp-video-tutorials.blogspot.com/2018/01/angular-select-options-from-array-slides.html Angular CRUD Tutorial https://www.youtube.com/watch?v=rJ9o4TyhSuo&list=PL6n9fhu94yhWUcq5Pc16uf8YKXoZ87Vh_ Angular CRUD Tutorial Text Articles & Slides http://csharp-video-tutorials.blogspot.com/2017/12/angular-crud-tutorial.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists In this video, we will discuss, how to get the select list options from an array in the component class, instead of having them hard-coded in the HTML. 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 Tutorial - CSSStyleDeclaration Object - Element's inline CSS style
 
10:05
The CSSStyleDeclaration interface represents a CSS declaration block, including its underlying state, where this underlying state depends upon the source of the CSSStyleDeclaration instance. interface CSSStyleDeclaration { attribute DOMString cssText; readonly attribute unsigned long length; getter DOMString item(unsigned long index); DOMString getPropertyValue(DOMString property); DOMString getPropertyPriority(DOMString property); void setProperty(DOMString property, [TreatNullAs=EmptyString] DOMString value, [TreatNullAs=EmptyString] optional DOMString priority = ""); void setPropertyValue(DOMString property, [TreatNullAs=EmptyString] DOMString value); void setPropertyPriority(DOMString property, [TreatNullAs=EmptyString] DOMString priority); DOMString removeProperty(DOMString property); readonly attribute CSSRule? parentRule; attribute DOMString cssFloat; }; The cssText attribute must return the result of serializing the declarations. The length attribute must return the number of CSS declarations in the declarations. The item(index) method must return the property name of the CSS declaration at position index. 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
