javascript - 如何循环遍历 Alexa Intent 中的对象数组？

Question

所以问题是我无法在 quizIntent 处理程序的循环中遍历问题数组。仅显示第一个问题，然后不再移动。其余代码工作正常。我想做的是继续提问，直到数组中的问题用完，并在用户给出错误答案时跳出循环。

我只是 Alexa 编程的新手。请帮忙。

这是我的数组

    const got = [
    {
        question: "Grey Wind, Lady, Ghost, Shaggydog, Summer and the sixth direwolve's name is?",
        answer: 'nymeria',
    },
    {
        question: "What was the name of the sinister castle where Arya and Gendry were held prisoner in season two?",
        answer: 'harrenhal',
    },
    {
        question: "What is a person called that can enter the minds of animals?",
        answer: 'warg',
    },
    {
        question: "What was the name of the Stark ancestral sword that was melted down by Tywin Lannister?",
        answer: 'ice',
    }
];

这是我的 Alexa Intent

    var handlers = {
  "customIntent": function () {
           this.response.speak("Would you like to appear for a trial by combat");
      this.emit(":responseReady");
   },
   "quizIntent": function () {
       var mydecision = this.event.request.intent.slots.decision.value;
       if(mydecision=='no'||mydecision=='nope'||mydecision=='naah'){
        this.response.speak("A five year old has more courage than you.");
        this.emit(":responseReady");
       }

       for(var i = 0; i <got.length; i++){
            var myanswer = this.event.request.intent.slots.answer.value;
            var item = got[i].question;
            this.response.speak(item).listen();
            if(myanswer!=got[i].answer){
                this.response.speak("Wrong Answer. You are dead");
                this.emit(':responseReady');

            }
            if(i==got.length-1){
                this.response.speak("You won");
                this.emit(':responseReady');
            }

      }


   },
   "LaunchRequest": function () {
    this.response.speak("Valar Morghulis").listen("You are supposed to say Valar Dohareis"); 
    this.emit(":responseReady");
   }

};

如果你也想看的话，这是我的 Intent Schema

for循环没有任何作用 intent旨在对每次调用给出单一响应。所以虽然你是for循环将运行，它不会发出第二个响应，因为在第一次迭代的 listen 方法之后执行将从一开始就开始，因为它是一个新的调用。

使用Session attribute可以顺利达到你想要达到的目的。

var iterations = 0; //defined globally

// Later on, for every iteration, you simply need to call 
// into the attributes property of the alexa object to change the value.

this.attributes['iterations'] = iterations + 1;
