Setting a global variable to control the visibility of the primary Navigation Menu

Implementing a log-in screen in my Angular app has presented me with the challenge of hiding the main navigation bar while the log-in screen is active. Once the user successfully logs in, I need to display the main nav again. Currently, the main nav is part of the Index.html file, which is the first file served and also where ng-app is defined. I am aware that I can use the ng-show attribute, but I'm unsure how to specify the condition for ng-show that can be accessed and modified from different parts of my single-page application. Any guidance or examples using $rootScope or similar solutions would be greatly appreciated.

Answer №1

Each scope is linked to $rootScope through its own $root element. This means that you can easily access it within your HTML code using:

ng-show="$root.showMainNav"

In this example, 'showMainNav' is a property on $rootScope that determines the visibility of the main navigation bar.
