how to call a function from another function

Dec 22, 2016 at 09:32 PM | 116 Views

I have my controller file in which I call a function on another file, then from that function I wan to call another function within that file but I'm unable to do that.

controller.js code

onPricePress: function(evt) {
   //some code here
   ....
  //now what I want here
   formatter.test.apply(this); //formatter is the reference to my other file and calls the function test().
  
}

formatter.js code

test: function(){
//some code here
....
//now what I want

var displayColor = evaluateColorFormat(DLAPrice, proposedPrice); //this is my other function

},
evaluateColorFormat(DLAPrice, proposedPrice){

//do something
}

so I want to call evaluateColorFormat() function from test() but I cannot do that, it says the reference to that function doesn't exist. I tried using this.function() format but it gives me the same error. I saw a solution on stackoverflow but that makes use of this.function() which doesn't work for me. Any ideas anyone?

      Already tried that and doesn't work. The reason for it not working is that when I call formatter.test() from my controller I attach "this" to it, which means that test() has a controller object reference, so when using this.something() inside formatter.test() it points to the controller object, which doesn't have the evaluateColorFormat() function.

    Hi,

    Can you paste your entire Formatter. I solved your problem like this :

    MyFormatter: 

    jQuery.sap.declare("model.formatter");

model.formatter = {
           
        testFunc:function(a,b) {
            console.log('called');
            model.formatter.testFunc2();

        },
        testFunc2: function () {
            console.log('called func 2');
        }
};

    And call in my Controller is same as yours :

    this.formatter.testFunc.apply(this);

      I found a solution to this. The solution above would work but I was calling the first function from another file. I found a way to make it work already thanks.
