Tips for declaring and utilizing multiple functions within an Angular JS Factory, as well as executing one function inside another

Could someone assist me in creating multiple functions within an AngularJS Factory? I am looking to access the returned value from one function and process it in another function. I attempted the code below without success.

In the following function, I want to retrieve the value in the modifyProduct function that we receive from getProduct(response.data)

I have looked at the questions below but did not gain much insight:

AngularJS : From a factory, how can I call another function

Calling a function in another function with AngularJS factory

 app.factory('ProductsService', function($http) {
  function getProduct() {
    return $http.get('finalmsodetails.json').then(function(response) {
      console.log(response.data);
      return response.data;
    });
  }

  function modifyProduct() {
    this.getProduct().then(function(value) {
      console.log(value);
    });
  }
  return {
    getProduct: getProduct,
    modifyProduct: modifyProduct
  };
});

Answer №1

You're almost there. Simply remove this. since the function you are invoking is defined locally, not as a method of an object. Additionally, it would be beneficial for `modifyProduct` to return the promise so that any caller can determine its success or failure.

function updateProduct() {
  return getProduct().then(function(result) {
    console.log(result);
  });
}
