我使用AngularJS应用程序。我尝试从level1question一次访问一个问题及其选项。实际上我无法访问问题及其选项。
JSON
{
"_id":1,
"level1question":[
{
"question": "Which one is correct team name in NBA?",
"options": [
"New York Bulls",
"Los Angeles Kings",
"Golden State Warriros",
"Huston Rocket"
],
"result": 3
},
{
"question": "5 + 7 = ?",
"options": [
"10",
"11",
"12",
"13"
],
"result": 2,
},
{
"question": "12 - 8 = ?",
"options": [
"1",
"2",
"3",
"4"
],
"result": 3
}
]
}
HTML
<div>
{{currentQ.question}}
</div>
<div class="buttonMCQ">
<button class="ans"
ng-repeat="option in currentQ.options">
{{option}}
</button>
</div>
AngularJS控制器
$http.get('http://v1/level.json').success(function(res){
$scope.myData = res;
jsonData = $scope.myData;
$scope.currentQ = jsonData[next];
}).error(function (err){
console.log(err);
});

从提供的有限的JS代码中，很难确切地说出你想要做什么，但是我认为你正在寻找here is a DEMO。
<body ng-app="myApp" ng-controller="myCtrl">
<div>
{{currentQ.question}}
</div>
<div class="buttonMCQ">
<button class="ans" ng-click="nextQuestion()" ng-repeat="option in currentQ.options">
{{option}}
</button>
</div>
</body>
var app = angular.module("myApp", [])
.controller("myCtrl", function ($http, $scope) {
var next = 0;
$scope.getNextQuestion = function () {
$http.get('level.json').success(function(res){
$scope.myData = res;
jsonData = $scope.myData;
console.log(jsonData["level1question"][next]);
$scope.currentQ = jsonData["level1question"][next];
}).error(function (err){
console.log(err);
});
};
$scope.getNextQuestion();
$scope.nextQuestion = function () {
next = (next + 1) % 3;
$scope.getNextQuestion();
}
});
