How to call another scope function in AngularJS

Question

In AngularJS, I have 2 scope function in the controller,

$scope.fn1 = function(){
//do something A
};

$scope.fn2 = function(){
    //do something B
    //I want to call fn1 here.
};

If my fn2 want to call fn1, how can I do? Thanks!

Since both functions are in the same scope you can simply call $scope.fn1() inside fn2.

Fn1() must be declared before call it on fn2()

I have the same issue. fn1() just isn't being called and I don't understand why.

$scope.fn1 = function() {
    // do something A
};

$scope.fn2 = function() {
    // do something B
    // I want to call fn1 here.

    $scope.fn1(); // this works

};

if you are doing same thing inside both fn1 and fn2 you don't want two scope function, use one function for that.

if you need to addition in fn2 then take common thing for out of two functions then call that.

I think you should show the user how to do what he asks. He may use fn1 not only from fn2, but from anywhere else
