Implementing a custom body class in AngularJS when utilizing partials

Looking for some help with AngularJS.

I have an index.html file, along with controllers and partials.

The <body> tag is located in the index.html. I am trying to set the class for the body using my controller.

After adding a value to $scope.body_class and referencing it in my index.html like this:

<!doctype html>
<html lang="en" ng-app="myGreatApp">
...
<body ng-class="{body_class}"> {{body_class}} Hi!

Unfortunately, body_class doesn't return any value.

How can I successfully retrieve a value from body_class?

Answer №1

When using directives in AngularJS, it is important to define the controller on the element or a parent element in order for them to interact properly. Alternatively, you can inject $rootScope and use it instead. The ng-class directive accepts a hash like this:

<body ng-controller="YourController" ng-class="{body_class: <expression>}"> {{body_class}} Hi!

If <expression> evaluates to true, the element will receive a html class corresponding to the key in the hash.

<body ng-controller="YourController" ng-class="{body_class: true}" class="body_class"> whatever value $scope.body_class has Hi!

Alternatively, if you do not want to declare the class name in the markup, you can directly bind it using ng-class like this:

<body ng-controller="YourController" ng-class="body_class"> {{body_class}} Hi!

For more information, refer to the ng-class documentation

Answer №2

Give this a try:

Controller

function DisplayCtrl($scope){
$scope.MyText = 'Welcome'
}

HTML

<body data-ng-app="" data-ng-controller='DisplayCtrl'>
<div data-ng-class="MyText">Welcome to the world
</div>
</body>
