Issue
I’m trying to find an elegant way to have a custom dynamically class of the body tag that I can set easily from the ui-router configurations
and if none is set, I can use a default option or none.
Example:
routes.js
$stateProvider
.state('login', {
url: "/login",
template: 'Login'
})
.state('register', {
url: "/register",
template: 'Register'
}).
.state('profile', {
url: "/profile",
template: 'Profile'
});;
Simple markup HTML
<html>
<body class=""> <!-- Dynamically class to change -->
<div ui-view></div>
</body>
</html>
Scenario:
1 – Visiting the state
login I should have the class of the body equals to auth
2 – Visiting the state
register at this point it will have the same auth
class
3 – Visiting the state
profile the body will have the default class or none
How do you achieve that?
Solution
You can have a master AppController that controls this:
<html ng-app="app" ng-controller="AppController as appController">
...
<body class="{{ appController.bodyClasses }}">
Inside AppController:
var vm = this;
vm.bodyClasses = 'default';
// this'll be called on every state change in the app
$scope.$on('$stateChangeSuccess', function(event, toState, toParams, fromState, fromParams){
if (angular.isDefined(toState.data.bodyClasses)) {
vm.bodyClasses = toState.data.bodyClasses;
return;
}
vm.bodyClasses = 'default';
});
Inside your route defs:
.state('register', {
url: "/register",
template: 'Register',
data: {
bodyClasses: 'auth'
}
});
See UI Router documentation for more on this data-attribute strategy.
