angular 4 host listener on resize parent

To create a new directive we will use the generate command of ng cli. For Angular 11 you can use version 2.1.0 which internally uses uses ResizeSensor from CSS Element Queries that is supported in IE.

It is as simple as:

It internally uses browser native ResizeObserver. angular 4 host listener on resize parent

Let’s create a new Directive in the Angular application to demonstrate an element Highlighter directive which will include color input by a user and mouse events to highlight the background of a div. Angular 14 directive for detecting changes of an element size. In this tutorial, we will create a custom directive example from scratch which will take user inputs from a directive element and use them in event listeners. Take notice that all of the code to listen to key events will be on the TypeScript side of the component unlike the local click events in the template.Angular custom directives can take inputs using and add event listeners to elements using Angular post is compatible with Angular 4 upto latest versions, Angular 7, Angular 8, Angular 9, Angular 10, Angular 11, Angular 12 and Angular 13 So in our template we show a single property value and then have two buttons that call the increment() and decrement() methods. Let's take a look at the component template first. In our rendered counter component I can increment and decrement the value with the buttons and the keyboard arrow keys. We will listen to the keyup event to be able to use the keyboard arrow keys for the component. Our counter component will have two buttons. In our example, we have a simple counter component that can increment and decrement a value on the view. This API allows us to register a particular listener for events in the browser and then call methods in our components to react to them. To listen to the window for events, we will use the HostListener API. There is a specific API within Angular we can use to listen to the global window and document events like the keyup and keydown events. With Angular, we try to avoid touching the DOM directly for certain rendering and performance reasons.

Typically we register window and document events to accomplish this. This great for user experience and accessibility.

But if you need just in code as wrote:

A typical pattern in many web applications is the ability to react to users via keyboard events or shortcuts. Better way is to use parent container component and child to operate.
