Creating template variable based on $state in AngularJS

Question

Creating template variable based on $state in AngularJS

Here is what I currently have:

<span>{{ $root.page_header || "default" }}</span>

However, I want it to default to default unless the current $state is a specific value.

For example, if my states are: home, settings, & profile, then I want $root.page_header to be default as long as the $state is not home. If it is home, then my controller will define what $rootScope.page_header should be.

I believe I need to first determine the $state name and then incorporate it into my {{ }} somehow.

Any suggestions on how to achieve this?

Answer №1

If you're looking to handle logic directly in the view, one option is to utilize JavaScript's inline if statement, also known as the Conditional (Ternary) Operator.

<span>{{ $root.page_header == 'home' ? $root.page_header : "default" }}</span>

Alternatively, if you prefer to manage this logic within your controller:

$scope.page_header = $root.page_header == 'home' ? $root.page_header : "default";

You can then display the value in the view using:

<span>{{page_header}}</span>

or

<span ng-bind="page_header"></span>

Additionally, you can retrieve the current state name with:

$scope.page_header = $state.current.name;
console.log($scope.page_header)
