Utilizing one-way data binding with Angular 2 in HTML is similar to the approach used in Angular 1, employing the

Is there a method in Angular 2 to achieve one-way data binding similar to what we did in Angular 1?

<!DOCTYPE html>
<html lang="en-US">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<body>

<div ng-app="">
<h4>Please change the text box value to see the scenario</h4;
  <p>Name : <input type="text" ng-model="name" 
ng-init="name='change me '"></p>
  <h1>Hello {{name}}</h1>
<h2>One-way binding- </h2>
{{::name}}
</div>

</body>
</html>

How can we accomplish this with Angular 2? What are the alternative options available?

Note: I am looking for an updated value at the @component end without reflecting changes only on the HTML UI.

Answer 1

Answer №1

The concept of two-way data binding in Angular 2 can be demonstrated by the following code:

<input type="text"  [(ngModel)]="name">

On the other hand, one-way data binding in Angular2 is accomplished by removing parentheses, like so: [ngModel]

<input type="text"  [ngModel]="name" (ngModelChange)="onChange($event)">
onChange(newvalue) {
//perform actions with newvalue
}

I trust this explanation clears things up for you!
