Property Binding

Property Binding in Angular

Property Bidning uses the square-brackets to update the property in an HTML-Element based on the expression written infront of it.

Practical Example of "Property Binding"

  2. Add the home component in the app.component.html file removing all boilerplate code there.
  3. We will use source url of an image and a disabled boolean variable to show how property binding can be achieved in 3 ways.


<img src="./../../../assets/img/hermione.png" />


<img src="{{sourceLink}}" />
<img bind-src="sourceLink" />
<img [src]="sourceLink" />


<input type="text" disabled />


<input type="text" disabled="{{isDisabled}}" />
<input type="text" bind-disabled="isDisabled" />
<input type="text" [disabled]="isDisabled" />


import { Component, OnInit } from '@angular/core';

  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
export class HomeComponent implements OnInit {

  sourceLink: string = "./../../../assets/img/hermione.png";
  isDisabled = true;

  constructor() { }

  ngOnInit() {



img {width:100px;}
  1. You'll get the following result.

Setting 'isDisabled' variable to false, renders:
