What is the best way to utilize ng-if in the index.html page depending on the URL?

Is there a way to hide certain elements in the index page based on the URL of nested views? In my index.html file, I am looking to implement something like this:

    <top-bar ng-if="!home"></top-bar>
    <ui-view class="reveal-animation"></ui-view>
    <bottom-bar ng-if="!home"></bottom-bar>

I would like for the top and bottom bars to disappear when navigating to the "home" view. I have seen similar questions suggesting the use of $location in the controller, but where exactly is the controller for the index page located?

Thank you.

Answer №1

If you want to update your parent controller, try adding the code below:

$scope.isHome = function(){
  return $state.is("home");
}

Next, make changes to your template as shown here:

<top-bar ng-if="!isHome()"></top-bar>
<ui-view class="reveal-animation"></ui-view>
<bottom-bar ng-if="!isHome()"></bottom-bar>

For a live example, check out this plunkr link.

Another way to achieve this is by using $stateChangeSuccess, like so:

$scope.$on("$stateChangeSuccess", function(event, toState){
  $scope.isHome = (toState.name == "home")
})

Don't forget to explore $state.includes, $state.current, and other options. Refer to the documentation here

Learning everything at once can be overwhelming. Sometimes it's better to focus on a few key concepts first.
