Ways to verify the $window variable in ng-if or ng-show

One variable named variable1 has been declared, and I am looking to validate this variable across all pages using ng-if or ng-show.

Answer №1

One approach is to bind the variable to the $rootScope. Here's an example:

var app = angular.module('app', []);
...
app.run(function($rootScope){
  $rootScope.myspecialvar = "hello";
});


...
//can be used in js
app.controller(function($rootScope){
  console.log($rootScope.myspecialvar);
});
<!-- can be used in html -->
{{myspecialvar}}
<!-- or -->
<div ng-if='myspecialvar'></div>
