We believe in learning things from scratch and always take up courses that will start from the absolute beginning and leave no stone unturned in order to provide you with the knowledge that you deserve.
Choosing a course might be a tough job as there are so many courses on the internet and a vast platform to learn in. But hey, don’t disappoint yourself already because we will tell you exactly what you need to look for in a course before enrolling in one.
In this article, we will learn about the Angular js Course, its perks and cons, its need in today’s world, and a lot more. Keep reading and gain as much material as you can because this course might shape your future, for the better.
The basics of Angular js Training start off with having a basic knowledge of JavaScript, CSS, and HTML. The sole motive of Angular js is to provide a simplified solution to application development and check its performance with the help of a framework known as Model View Controller (MVC) Architecture. What MVC does is that it changes the bulk codes of programming into simple forms of code that are easy to use and understand.
To learn this course, you must have a keen interest in the same. This is because, without interest and passion, you will not be able to fully devote yourself to this magical course.
What are Angular js Training’s Objectives?
There are a lot of things that angular js does. A few major objectives are discussed below:
- Reducing the code in order to build user interface applications.
- Creating single-page applications.
- Restoring data from a back-end server and then manipulating it into helping the code.
Now, you must be thinking if AngularJs is difficult to learn. Well, the answer is – No.
Angular js is an easy framework to learn, especially if you have some basic knowledge of JavaScript beforehand.
What are the Basics of AngularJs Training?
The Angular js is linked with Directives, which binds data to HTML with the help of expressions. Now, how is it done exactly?
Well, here are some basic extended HTML:
- ng-app – This directive is made for defining js applications.
- ng-model – This directive binds the value of HTML controls (input, text area, select) to any application data.
- ng-bind – This directive is the one that binds data to HTML.
For example :
<!DOCTYPE html>
<html>
<script src=”https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js”></script>
<body>
<div ng-app=””>
<p>Name: <input type=”text” ng-model=”name”></p>
<p ng-bind=”name”></p>
</div>
</body>
</html>
Explanation of the example :
- The ng-app instruction is telling AngularJs that <div> element should be the “owner” of the app of Angularjs.
- ng-model directive is the one that links the input field values to the name (the app variable).
- The ng-bind directive is the one that binds the whole content of the <p> element to the name (application variable).
The Modules of Angular js
The modules of Angularjs describe an application. It is a vessel that contains the different parts of any application and application controllers.
A module is created using a function –
angular. module
For example –
<div ng-app=”myApp”>…</div>
<script>
var app = angular.module(“myApp”, []);
</script>
Here, “myApp” denotes an HTML element. After this, you are free to add filters, directives, controllers and so on.
How to add a Controller?
<div ng-app=”myApp” ng-controller=”myCtrl”>
{{ firstName + ” ” + lastName }}
</div>
<script>
var app = angular.module(“myApp”, []);
app.controller(“myCtrl”, function($scope) {
$scope.firstName = “John”;
$scope.lastName = “Doe”;
});
</script>
The Directives of Angular js
Directives are the new attributes that help you extend HTML. Angularjs already contains a set of existing directives that help you by offering functionality to your applications. You may also define your own directives.
What is Data Binding?
Data Binding is a function in AngularJs that binds Angularjs expressions with Angular js data.
For example –
<div ng-app=”” ng-init=”quantity=1;price=5″>
Quantity: <input type=”number” ng-model=”quantity”>
Costs: <input type=”number” ng-model=”price”>
Total in dollar: {{ quantity * price }}
</div>
Here, two text fields (as shown) are bound together with the help of two ng-model directives.
How to Create New Directives?
You have the ability to create your own directives here. They can be created by using the function (directive)
For example –
<body ng-app=”myApp”>
<w3-test-directive></w3-test-directive>
<script>
var app = angular.module(“myApp”, []);
app.directive(“w3TestDirective”, function() {
return {
template : “<h1>Made by a directive!</h1>”
};
});
</script>
A directive can be invoked using:
- Class
- Attribute
- Comment
- Element name
For example –
- Element name
<w3-test-directive></w3-test-directive>
- Attribute
<div w3-test-directive></div>
- Class
<div class=”w3-test-directive”></div>
- Comment
<!– directive: w3-test-directive”>
What are the Restrictions?
You also have the feature to restrict your directives to ensure that they are only invoked by some of the given methods.
For example –
var app = angular.module(“myApp”, []);
app.directive(“w3TestDirective”, function() {
return {
restrict : “A”,
template : “<h1>Made by a directive!</h1>”
};
});
Here, by adding restrict with “A”, the directive has only been invoked by attributes.
Given below are the legally restrict values:
- M for Comment
- C for Class
- A for Attribute
- E for Elements
