How to create global controller to all views?

Question

I am very new to angular and JS and do not know how to implement very simple behavior. So... I have an angular-route module and all my views are changed with ng-view directive. Here is the declaration

<body>
    <div class="row main" ng-view> </div> 
<body>

I have all controllers connected to those views. Also I have one common controller to all views, I check cookie in that controller. How to call that controller automatically in all other views without dependency on that controller from others?

I tried to put it in but it is called only once on the index page.

the question for me would be is it really a controller that you need. As i understand you do want to execute some code (for cookie checking) for every page, what is probably not needed. If you want to check if the user has a cookie i would recommend doing this in the app code. — AirBorne04, Sep 25 '14 at 19:12

You can do something like this:

<body>
    <div ng-controller="globalController">
        <div class="row main" ng-view> </div> 
    </div>
<body>

This doesn't help. This div will not updated when angular change the view. – yu.pitomets Sep 25 '14 at 19:14
@user1315599 you are right but you can periodically check for cookie with $interval to overcome this limitation. – Marian Ban Sep 25 '14 at 19:21
I need to check cookie each time user change the view. Because information on the view depends if user was log in. – yu.pitomets Sep 25 '14 at 19:23
@user1315599 i updated my example to fit better to your needs. – Marian Ban Sep 25 '14 at 19:40
this is absolutely the same as before – yu.pitomets Sep 25 '14 at 20:46

Look at my plunker and check the developer console.it will show a log message while you navigating. – Marian Ban Sep 25 '14 at 20:57

A controller, by definition, is meant to prepare the data to be passed to the view.

I would recommend you to do this with a service instead.

This service could then be accessed by whatever view you are in.

You could imagine, for example, to implement a resolver in you $routeProvider.when which will read the Cookie from this service. $route also trigger events whenever the view is changing, will change or has changed. Try to leverage this, this is really powerful.
