AngularJS - Accessing ng-init variables from run method

Question

1) I have variables initialized in ng-init Eg -

ng-init="password='Mightybear'";

2) I want to access it from the .run method. Eg -

anguar.module("ngApp", [])
.run(function() {
//Access password here
});

Below scenarios I have tried, and did not work -

1) angular.module("ngApp", [])
.run(function($rootScope) { 
console.log($rootScope.password) //undefined!!!
});

2) angular.module("ngApp", [])
.run(function($rootScope, $timeout) { 
$(timeout(function() {
console.log($rootScope.password) //undefined!!!
});
});

Answer 1

You can not get ng-init value inside your run block

Angular LifeCycle

1. Config Phase (app.config) ($rootScope will not available here)
2. Run Phase (app.run) ($rootScope will available here)
3. Directive Gets Compile()
4. Then controller, directive link function, filter, etc gets executed.(ng-init is here)

If you want to get initialize value in run phase then you need to set that value in config phase.

If You want to set the value in config then you can take use of app.constant/provider which available in configuration phase, don't use $rootScope that is considered as bad pattern in AngularJS.

Code

var app = angular.module('app', []);

app.constant('settings', {
    title: 'My Title'
})

app.config(function(settings) {
    setting.title = 'Changed My Title';
    //here can you do other configurarion setting like route & init some variable
})

app.run(function(settings) {
    console.log(settings.title);
})
