如何在ng-if或ng-show中检查$ window变量

Question

我声明了一个变量var variable1，我需要使用ng-if或ng-show检查所有页面中的变量

Answer 1

one of the ways is to attach the variable to the $rootScope . For 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>
