How to call method without oEvent

Question

How to call Event handler from a method of the controller?

<Button text="click" tap=".BtnTap" />

BtnTap: function(oEvent) {
  console.log("Button Tap");
},

doSomething : function() {
  BtnTap();
},

I want same BtnTap() call from another function in the controller.
It doesn't seem to be possible to access oEvent from another function.

Answer 1

it is not so elegant to directly to call the event handler. Maybe you can extract the logic in the event handler to another function.

BtnTap: function(oEvent) {    
    console.log("Button Tap");
    this.btnTapHelper();
}

btnTapHelper: function() {
    //logic here
}

doSomething : function() {
    this.btnTapHelper();
}
