I want to call a button of a component in other component and these two components are in different module
Use RxJs
BehavourSubject
!
You can declare BehavourSubject
type variable in your service/any of the component and use that to communicate between the components.
As its event driven, once you change the value of the variable, it notify all who subscribed to it.
So when you click on the button in any component, other components know that, that button is clicked and you can do what ever you want in your component.
// this can be declared in a service to shared between components
let btnClk = new BehavourSubject('oo');
// in the first compnent
clickBtn() {
btnClk.next('value to passed to other component');
}
// In the other component
btnClk.sunscribe((val)=>{
// val is the value passed
})
