[Question] How to create a global or from scope javascript function ?

[yaronmil]

I want to reuse a calculate value javascript functin .

I want to be able to call the same function from differant component.

how can it be done ?
is it possible to do so without using the global window objec ?

you can create a function inside a service and use it anywhere in your application by injecting that service. Angular services are designed to share functionality and data across components, directives, or other services.

Yeah, the only way you're going to be able to "reuse" a function within the form's evaluation context (so, within a calculated value for example) is either by attaching it to the global scope or by injecting it into your form's evaluation context by using the form's module, e.g.

myForm.module = {
  options: {
    form: {
      evalContext: {
        validatePhone: function(input) {
          return input.match(/^[2-9]\d{2}-\d{3}-\d{4}$/);
        }
      }
    }
  }
}

(this way you could reuse the validatePhone function across a number of forms
