Getting element height
The correct way is to use @ViewChild()
decorator:
https://angular.io/docs/ts/latest/api/core/index/ViewChild-decorator.html
Template:
<div class="view-main-screen" #mainScreen></div>
Component:
import { ElementRef, ViewChild } from '@angular/core';export class viewApp{ @ViewChild('mainScreen') elementView: ElementRef; viewHeight: number; constructor() { } clickMe(){ this.viewHeight = this.elementView.nativeElement.offsetHeight; }}
That should do it but obviously you need to add your Component decorator.
Edit:
For Angular 8 or later you need to provide the 2nd parameter in ViewChild
@ViewChild('mainScreen', {read: ElementRef, static:false}) elementView: ElementRef;
update2
constructor(private elementRef:ElementRef) {}someMethod() { console.log(this.elementRef.nativeElement.offsetHeight);}
Accessing nativeElement
directly is discouraged but current Angular doesn't provide other ways as far as I know.

mhevery commented 12 days ago We have decided to remove Ruler service, and so it is not part of the public API.

As far as I know the Ruler
class should provide that functionalityhttps://github.com/angular/angular/blob/master/modules/angular2/src/platform/browser/ruler.ts if this isn't enought you probably need to access elementRef.nativeElement
and use direct DOM access and functions provided by the elements.
new Ruler(DOM).measure(this.elRef).then((rect: any) => {});
Rules service is safe in WebWorker. See also the comments on https://github.com/angular/angular/issues/6515#issuecomment-173353649
<div *ngFor="let item of items" (click)="itemClick($event.currentTarget)"></div>itemClick(dom){ var height=dom.clientHeight; // ...}
