Implementing the handling of multiple button events in a ListView through onclick function

Currently, I have a listview with three buttons that need to trigger the same method checkInstall on multiple button clicks. However, I am unsure of how to achieve this. Below is the relevant code snippet:

html file:

 <ListView [items]="allAppsList" class="list-group">

   ....... 
   .......
   <StackLayout row="0" col="2">

      <Button  text= "Install" (tap) ="checkInstall($event, myIndex)" > </Button>   
      <Button text= "Open" (tap) ="checkInstall($event1, myIndex)" > </Button>   
      <Button text= "Remove" (tap) ="checkInstall($event2, myIndex)" > </Button>   

  </StackLayout>
 </ListView>  

ts file:

checkInstall(args: EventData, index : number) : void {

}

While the checkInstall method works fine for the first button, I am facing challenges in obtaining separate button IDs for the second and third buttons to trigger different functionalities within checkInstall such as hiding and showing buttons.

Answer №1

$event is a reserved keyword in Angular that holds the emitted value and cannot be changed

<Button text="Install" (tap)="checkInstall($event, 1, myIndex)"></Button>
<Button text="Open" (tap)="checkInstall($event, 2, myIndex)"></Button>
<Button text="Remove" (tap)="checkInstall($event, 3, myIndex)"></Button>

You are able to pass parameters to your method for further processing

checkInstall(args: EventData, buttonIndex: number, index: number): void {

}
