Question

大家好，每个人都可以帮助我....... 我试图将var declare作为global＆amp;在angularJS

中的$ scope.funcName中计算

1。 HTML

  {{totalmarks}}

2。控制器

var next = 0;
  var marks = 0;
  var total;
  $http.get('../js/commonquiz.json').success(function(res){
  $scope.myData = res;
  jsonData = $scope.myData;
  noOfQuestion = jsonData.length;
  $scope.currentQ = jsonData[next];
  }).error(function (err){
  console.log(err);
  });
  $scope.change_question = function(selected,option,index){
  var rightAns = $scope.currentQ.result //Get Result value
  if (index == rightAns){ //compare selected value with rightANS
  $scope.rightOption = index;
  marks = marks + 1;
  total = marks;
  } 
  }
  $scope.totalmarks = total;
