UI Router dynamic <title> tag

问题:

I'm adding a title to every state in the ui-router like that:

.state('projects', {
    url: '/',
    templateUrl: 'projects/projects.html',
    ncyBreadcrumb: {
        label: 'Projects'
    },
    data : {title: 'Projects'}
})

And then the title attribute takes that data:

<title ng-bind="$state.current.data.title"></title>

How can I take data from the state parameters and add it to the title in the above example? I tried the following with no luck:

.state('project', {
    abstract: true,
    url: '/projects/:projId',
    resolve:{
        projId: ['$stateParams', function($stateParams){
            return $stateParams.projId;
        }]
    },
    controller: 'projectCtrl',
    templateUrl: 'project/project.html',
    ncyBreadcrumb: {
        label: 'Project',
        parent: 'projects'
    },
    data : {title: '{{state}}'}
})

you have to use app.run() in your app.js file and assign your title in $rootScope.title . you can follow this code

app.run(function($rootScope){
    $rootScope.$on('$stateChangeStart', function(event, toState, toParams, fromState){

        $rootScope.title=toState.data.title;
    });
});

after this then bind the variable in your html like this

<title ng-bind="title"></title>

I think it will helpful

There is a working example

I would say, you are almost there. The title could look like this:

<title>{{$state.current.data.title}} {{$stateParams.ID}}</title>

Let's have these two states:

  .state('parent', {
      url: "/parent",
      templateUrl: 'tpl.html',
      data : { title: 'Title for PARENT' },
  })
  .state('parent.child', { 
      url: "/child/:ID",
      templateUrl: 'tpl.html',
      controller: 'ChildCtrl',
      data : { title: 'Title for CHILD' },
  })
  ;

And call them like this:

<a ui-sref="parent">
<a ui-sref="parent.child({ID:1})">
<a ui-sref="parent.child({ID:2})">

And with this hook:

.run(['$rootScope', '$state', '$stateParams',
  function ($rootScope, $state, $stateParams) {
    $rootScope.$state = $state;
    $rootScope.$stateParams = $stateParams;
}])

So, the point is, that in a $rootScope we can access both, $state.current and $stateParams

Check it here (NOTE, to see plunker in separated window, click the right -top corner blue icon - new window will change the title as well)

I'd suggest you to use params option instead of using data option, because params can be optional and you can set it dynamically by passing parameter inside your $state.go or ui-sref directive.

Code

.state('projects', {
    url: '/',
    templateUrl: 'projects/projects.html',
    ncyBreadcrumb: {
        label: 'Projects'
    },
    params: {
        title: { value: null }
    }
});

From Controller

$state.go('projects', {title: 'Page1'}); //you can change title while calling state

From HTML

ui-sref="projects({title: 'Something Else'})"
