angularjsHow do I use an AngularJS directive?

An AngularJS directive is a JavaScript object that augments an HTML element with custom behavior. To use a directive, you first need to include the directive in your HTML page. This can be done by either adding an attribute to the HTML element or by adding an element.

For example, the following code adds the ng-app directive to the <html> element:

<html ng-app>

The ng-app directive tells AngularJS to treat the element and its children as an AngularJS application.

Once the directive has been included in the HTML page, you can use it to add behavior to the element. For example, the following code uses the ng-model directive to bind the value of the <input> element to the name property of the $scope object:

<input type="text" ng-model="name" />

When the user types into the <input> element, the value of the name property of the $scope object is updated.

Directives can also be used to create custom elements and attributes. For example, the following code creates a new element called <my-directive>:

<my-directive></my-directive>

The directive can then be used to add custom behavior to the element. For example, the following code uses the ng-click directive to call a function when the element is clicked:

<my-directive ng-click="myFunction()"></my-directive>

When the element is clicked, the myFunction() function is called.

Directives are a powerful feature of AngularJS and can be used to create custom elements and attributes, as well as bind data to HTML elements.
