using
@Component()
class ChildComponent{
@Input("inputData")
private parentData:any
}
<parent> <child-comp [inputData]="someInfo"></child-comp> </parent>
allows seamless data transfer between the parent and child components through binding someInfo to parentData field
To pass data from a parent component to a child component in Angular, you can utilize the @Input() decorator. Here is an example:
In the parent component's HTML file, you define a variable or value that you want to send to the child component:
private label: string = 'Label Test';
In the parent component's HTML file, you assign this variable to the child component using square brackets:
<app-child [label]="label"></app-child>
In the child component's TypeScript file, you declare an input property for the label:
@Input() label: string;
In the child component's HTML file, you can then display the passed data using interpolation:
<label>{{label}}</label>
By following these steps, you can efficiently transfer information between your parent and child components within an Angular application.
One method to achieve this is by utilizing @ViewChild in Angular. Additionally, RxJS Subject and BehaviourSubject are effective tools for transmitting data between components, especially when dealing with independent components.
