angularjs - angular permission show message and set the button disabled -

-

i'm using "angular permission". validate user role , works perfect, want show message when user doesn't has these role , if possible shows button disabled. me this?

this router definition:

 $stateprovider.state('actionaccess', {url: '/actionaccess', templateurl: 'views/actionaccess.html', controller: 'actionaccesscontroller', data: { permissions: { only: ['admin'] } } })

and function define if user has or not role:

.run(function (permission, authorizationfactory){   // define anonymous role   permission.definerole('admin', function (stateparams) {     return authorizationfactory.isinrole("admin");   }); })

according the documentation on project page, can specify in router config redirectto property. 

data: {     permissions: {       except: ['anonymous'],       redirectto: 'login'     }   }
