In my code, I need to generate a random and numeric id and then assign to a parameter "id" in a different scope (i.escope.data = {id = "the random id"};) but being new to Angular, I have no clue how to do this!

  • Well you can generate it just using plain javascript with no need of using AngularJS; have a look at this question for instance https://stackoverflow.com/questions/105034/create-guid-uuid-in-javascript – Dario Sep 10 '17 at 19:23
  • Yeah but I am pushing all the data over http (POST) to an api and a random id is a mandatory field so javascript should not be involved in this case, right? Because then If I generate a id using js, I will have to post the entire data using js and that would be pointless! – Dhruv Shrivastava Sep 10 '17 at 19:25
  • it's not really clear what you are tying to accomplish here. what "different scope" are you talking about, and why would you think posting data to a server wouldn't involve JavaScript? What do you mean by "If I generate a id using js, I will have to post the entire data using js"?? **Angular is JavaScript**.... – Claies Sep 10 '17 at 19:28
  • this is definitely a case where a [mcve] would go a long way toward conveying what you are trying to do. – Claies Sep 10 '17 at 19:31
  • Umm the codebase I am working on involves 100% Angular and I cannot make a post request with JS because of one field, right? There must be a way to generate an id in Angular right? – Dhruv Shrivastava Sep 10 '17 at 19:32
  • Your still aren't making sense. AngularJs is a **Framework** written in the JavaScript **Language**. ***EVERYTHING YOU DO IN ANGULAR IS JAVASCRIPT***. what does "I can't make a post request with JS because of one field" mean? How else would you make a post request?? – Claies Sep 10 '17 at 19:34
  • let's say, for example, you have an object `$scope.data`, and it has a bunch of properties, but needs an `id`. why wouldn't `$scope.data.id = randomNumberFunction();` work? – Claies Sep 10 '17 at 19:36

first you need to generate it, the best is to set your function in a service or in the $rootScope.

With this way you can call your service function or by the $rootScope.

First generate an numeric id (updated function refer to this post )

Create GUID / UUID in JavaScript?

I will show you the example with the service :

(function () {
    'use strict';

    angular
        .module('your module app name')
        .factory('guidservice', guidservice);

    guidservice.$inject = ['$rootScope'];

    function partenairesservice($rootScope) {
        var service = {
              getGuid: getGuid,
        };

        return service;

        /*
        * Return numeric unik id of 16 chr.
        */
        function getGuid() {


    function s4() {
        return Math.floor((1 + Math.random()) * 0x10000);
      }
      return s4() + ''+ s4() + '' + s4() + '' + s4() + '' +
        s4() ;
    }
        }

    })();

to use then service function in any controller scope, inject the service (guidservice)

and then call guidservice.getGuid();
