javascript - AngularJS - Pass some flag from html to controller -

i new angular js. stuck, , not find solution.

problem - have html code given below :

<div ng-controller="mycontroller" ng-model={{tt="a"}}> </div> <div ng-controller="mycontroller" ng-model={{tt="b"}}> </div> <div ng-controller="mycontroller" ng-model={{tt="c"}}> </div> 

and controller code :

myapp.controller('mycontroller', function($scope) {     if($scope.tt == "a") //do     else if($scope.tt == "b) //do else }) 

note - html ng-model, wrote let know want.

question - want send controller html, can check value , conditionally.

this not best practice if want bring data in html angular can stash data property of window inside of <script> tag.

var app = angular.module('myapp',[]);  app.controller('mainctrl', function($scope){    $scope.tt = window.data;  })

<div ng-app='myapp'>    <div ng-controller='mainctrl'>      {{tt}}    </div>  </div>          <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>    <script>    window.data='abcd';  </script>
