angularjs单选按钮值检查

Question

当我选择单选按钮时没有任何反应。请chk我的jsfiddle，并帮助我找到我做错了什么。

var prnt = document.getElementById("prnt"); 
var app = angular.module('App', []); 
app.controller('aCtrl', function($scope) { 
$scope.correctAns = function(){ 
if($scope.chk === "false"){ 
prnt.innerHTML+="working"; 

}; 
}; 

}); 

这里是我的jsfiddle链接

这是你想要做什么？

var prnt = document.getElementById("prnt"); 
var app = angular.module('App', []); 
app.controller('aCtrl', function ($scope) { 

    $scope.chk = { 
     val: false 
    }; 

    $scope.check = function() { 
     if ($scope.chk.val === false) { 
      prnt.innerHTML = "True"; 
     } 
    } 
});
