Updating AngularJS to have the same page TITLE tag as the page's H1 tag

Question

Updating AngularJS to have the same page TITLE tag as the page's H1 tag

Is there a way to dynamically update the title tag of my page based on the H1 tag in AngularJS?

In jQuery, I could achieve this by:

var title = $('#content').find('h1').first().text();
if (title.length >= 1)
{
    document.title = 'My Site Name | ' + (title);
}
else {
    document.title = 'My Site Name';
}

What would be the best approach to do the same in AngularJS?

I prefer not to include this in the app.js file as it doesn't feel right to mix content that may change with code. If I modify the text of the H1 in my partial view, I want the title to automatically update.

Answer №1

To bind the title to static h1 content, you can utilize this custom directive:

var app = angular.module('bindTitle', []);
app.directive('bindTitle', ['$document', function($document) {
  return {
    restrict: 'A',
    link: function(scope, iElement) {
      $document[0].title += ' | ' + iElement.text();
    }
  };
}]);

The syntax for using it is:

<html>
<head>
  <title>My Site Name</title>
<head>
<body>
  <h1 bind-title>Your title</h1>
</body>
</html>

This will append Your title to the page title when the page loads, like so: My Site Name | Your title

Edit: automatic appending of title on h1 element

var app = angular.module('bindTitle', []);
app.directive('h1', ['$document', function($document) {
  return {
    restrict: 'E',
    link: function(scope, iElement) {
      $document[0].title += ' | ' + iElement.text();
    }
  };
}]);

The text within <h1> tags will now be added to the page title.

    }
  };
}]);

The text within <h1> tags will now be added to the page title.

To utilize Angular's data binding on the <title> tag, you have the option to use either ng-bind or ng-bind-template.

It is essential to store the desired value in a variable within your module/controller (e.g., $scope) for data binding to work effectively. If the value is not within the scope, Angular does not provide a more efficient solution than jQuery or traditional JavaScript (you will need to locate the <h1> tag on the page and extract the text manually).

angular.module('app', [])
.controller('MyCtrl', function($scope) {
    $scope.title = 'My Page';
});

<html ng-app="app" ng-controller="MyCtrl">
<head>
<!-- Example of direct binding -->
<title ng-bind="title"></title>

<!-- Alternatively, template example -->
<title ng-bind-template="My Site{{ title.length > 0 ? ' | ' + title : ''}}"></title>

To update the heading, utilize the $watch function.

<html ng-app="myApp">
  <body ng-controller="myCtrl">
    <h1>{{heading}}</h1>
    <input type="text" ng-model="heading" />
  </body>

  <script>
    angular.module('myApp', []).controller('myCtrl', ['$scope', function($scope) {
      $scope.$watch($scope.heading, function() {
        document.title = $scope.heading;
      });
    }]);
  </script>
</html>

In my opinion, the most straightforward approach is to assign identical model values to both your title and h1.

You can refer to this example on jsFiddle for clarification. As you type in the textbox, the value of name gets updated simultaneously in two locations.

Remember: It would be best to implement this mechanism within a MasterController designed for your Layout HTML page.
