我想在問題和答案json迭代。對於每個問題我有多個答案。我想用多個答案來展示每個問題。我想展示。預先感謝您的幫助。吳重複與條件

q1 
a1.1 
a1.2 
q2 
a2.1 
a2.3 
q3 
a3.1 
a3.2 
a3.3

JSON的樣子：

[{"QuestionID":101,"Question":"q1","Response":"a1.1","CorrectResponse":false}, 
{"QuestionID":101,"Question":"q1","Response":"a1.2","CorrectResponse":true}, 
{"QuestionID":102,"Question":"q2","Response":"a2.1","CorrectResponse":false}, 
{"QuestionID":102,"Question":"q2","Response":"a2.2","CorrectResponse":true}, 
{"QuestionID":103,"Question":"q3","Response":"a3.1","CorrectResponse":false}, 
{"QuestionID":103,"Question":"q3","Response":"a3.2","CorrectResponse":true}, 
{"QuestionID":103,"Question":"q3","Response":"a3.3","CorrectResponse":true}]

這是到目前爲止我的代碼

   var questions = []; 

       var answersWithCorrectCheck = []; 


       questions.push(test[0].Question); 
       answersWithCorrectCheck.push({ answer: test[0].Response, correct: test[0].CorrectResponse }); 

       for (i = 1; i < test.length; i++) 
       { 
        if(test[i - 1].QuestionID !== test[i].QuestionID) 
        { 
         questions.push(test[i].Question); 
        } 

        answersWithCorrectCheck.push({ answer: test[i].Response, correct: test[i].CorrectResponse }); 
       } 

       $scope.displayQuestionsPerTest = questions; 
       $scope.answersWithCorrectResonse = answersWithCorrectCheck;

請向我們展示一些代碼與您的實驗，我們可以嘗試。 – Andrea

謝謝我試圖將json分成兩個單獨的javascript數組。一個用於問題，另一個用於答案。我正在使用兩個ul列表。 – user6934713

問題解決了嗎？如果沒有，請分享代碼！ –

你可以做到這一點angular-filter，

<body ng-app="DemoApp" ng-controller="DemoController"> 
    <ul ng-repeat="(key, value) in data | groupBy: 'Question'"> 
    Question name: {{ key }} 
    <li ng-repeat="answer in value"> 
     {{ answer.Response }} 
    </li> 
    </ul> 
</body>
