I've tried to get offset data of the ponent in my angular app as below.

this.el.nativeElement.offsetWidth

But it is returning 0 if I don't pass it's css property as below.

this.renderer.setStyle(this.el.nativeElement, 'position', 'fixed');

it is working as I want.returning real value of the native ponent.But I don't want to change the position property.

Do you suggest me any solution to get current offset data like offsetWidth etc.. you can work on here.

• javascript
• angular
• dom
• angular7

• Is the object visible on the page? If not, measurements will always return 0. Maybe setting position is making it visible – Ruan Mendes Commented Jun 19, 2019 at 12:14
• yeah it is visible. @JuanMendes – seyid yagmur Commented Jun 19, 2019 at 12:15
• you need to use @ViewChild, you can check example here: stackblitz./edit/… – mocni_T Commented Jun 19, 2019 at 12:31

This happens because the ponent is an inline element by default. You can change its display style attribute to block or inline-block to get the correct size in code:

:host {
  display: block; /* or display: inline-block; */
}

See this stackblitz for a demo.

Some times the element might not have reference to the DOM object. Try doing change detection to refresh the reference. Sorry I am not able to ment.

import ChangeDetectorRef in the constructor

constructor(private changeDetect: ChangeDetectorRef) {}

@ViewChild('splashScreen') el: ElementRef;

getOffSetWidth() {
    // run change detection
    this.changeDetect.detectChanges();
    // And then try getting the offset
    const offsetWidth = this.el.nativeElement.offsetWidth;
    return offsetWidth; 
}
