コピーをFirebaseにプッシュ

Question

アレイのFirebaseノードに15コピーのオブジェクトをプッシュしようとしています。プッシュされるオブジェクトには、questionTextとanswerTextオブジェクトが含まれます。私はこの特定の部分のコードを書いていないので少し問題があります。

火災ベースquizTextは配列です。 submitQuiz法の下の方法のセクションでライン125上の下

私はquizText配列に結果の15枚のコピーを取得しようとするが、quizTextが定義されていないと言っています。私は何をすべきですか？

import db from '../db'; 

import ResourceCard from '../components/ResourceCard' 
import FlashCard from '../components/FlashCard' // display info after submitting the answers 
import Question from '../components/Question' 

import { mapMutations, mapGetters, mapState, mapActions } from 'vuex' 

export default { 
    name: 'quiz', 
    components: { 
     ResourceCard, 
     FlashCard, 
     Question 
    }, 
firebase() { 
    return { 
     resource: { 
      source: db.ref('resources/' + this.$route.params.resourceId), 
      asObject: true 
     }, 
    }; 
}, 
data() { 
    this.$store.commit('resetForm'); 

    return { 
     options: { 
      lightResource: true 
     }, 
     showLearn: true, 
     resourceId: this.$route.params.resourceId, 
     passedResources: [], 
     answeredQuestionsRes: [], 
     resourceLink: window.location.href 
    }; 
}, 
created() { 
    let passedRes = this.$firebaseRefs['passedResources'] = db.ref('/users/' + this.$store.state.userInfo.uid + '/passedResources'); 
    let answeredQuestionsRes = this.$firebaseRefs['answeredQuestions'] = db.ref('/users/' + this.$parent.$store.state.userInfo.uid + '/answeredQuestions'); 

    this.$bindAsArray('passedResources', passedRes); 
    this.$bindAsArray('answeredQuestions', answeredQuestionsRes); 

    // Swap out buttons 
    this.showLearn = false; 
}, 
computed: { 
    ...mapState({ 
     answers: state => state.quiz.answeredQuestions, 
     submitted: state => state.quiz.submittedStatus, 
     selectedCount: state => state.quiz.result.selectedCount, 
     result: state => state.quiz.result 
    }), 
    score() { 
     if (this.resource.quiz === undefined) return; 

     let isAnswer = (option) => option.isAnswer===true; 
     let totalCorrectAnswers = 0; 
     this.resource.quiz.forEach((question) => { 
      totalCorrectAnswers += question.options.filter(isAnswer).length; 
     }); 
     let selected = this.selectedCount; 
     let incorrectCount = (selected > totalCorrectAnswers) ? selected - totalCorrectAnswers: 0; 
     let correctCount = this.result.correctIds.length; 

     let amount = correctCount - incorrectCount; 

     if (amount < 0) { 
      amount = 0; 
     } 

     return { 
      amount, 
      total: totalCorrectAnswers // total correct answer count - used to calculated messages 
     }; 
    } 
}, 
methods: { 
    submitQuiz() { 

     this.$store.commit('displayAnswers'); 

     let getCorrectAnswerText =() => { 
      let result = {} 
      this.result.correctIds.forEach(({quizIndex, index}) => { 
       let quiz = this.resource.quiz[quizIndex]; 
       result[quizIndex] = result[quizIndex] || {}; // default to empty obj. 

       // Trying to make copies here. 

       Object.assign(result[quizIndex], { 
        questionText: quiz.text, 
        summaryText: quiz.summaryText, 
        [index]: { 
         text: quiz.options[index].text 
        } 
       }); 
      }); 

      return { 
       [this.resource['.key']]: { 
        quizText: quizText(15).fill(result) 
       } 
      }; 
     }; 

     if (!this.options.testMode) { 
      this.$nextTick(function() { 
       // delay to next tick, so we have latest computed values 
       console.log(this.score); 
       if (this.score.amount == this.score.total) { 
        // 100% answer 
        // Push specific resource object to Firebase under `/users/ ` + userInfo.uid + ` /passedResources` node ONCE score reaches 100% on submit. 
        // console.log('100% answer', this.$store.state.userInfo.uid) 
        let passedRes; 
        // save answered quiz in passedResources 
        // update times passed if all questions answered or score = 100% 
        // console.log('incPassedResource', this.resource); 
        this.$store.commit('incPassedResource', this.resource); // update store 
        // console.log('after mutation', this.$store.state.passedResources); 
        passedRes = this.$store.state.passedResources; 
        this.$firebaseRefs.passedResources.set(passedRes); 


        // save answeredQuestion as text in user/uid/answeredQuestion/resourceID 
        let answerData = getCorrectAnswerText(); 
        // console.log('answeredQuestions', answerData); 
        this.$firebaseRefs.answeredQuestions.set(answerData); 
        // no need to update store --> will be loaded into state in study component 

        // --> all questions answered - increment timesPassed on resource 
        let totalTimesPassed = parseInt(this.resource.timesPassed); 
        totalTimesPassed++; 
        // not working yet --> need to load timesPassed of resource, inc. & save back. or maybe use increment of firebase 
        this.$firebaseRefs.resource.child('timesPassed').set(totalTimesPassed); // todo firebase inc. would be handy here! 
       } 
      }); 
     } 
    } 
} 

}の代わりに

Answer 1

：

quizText: quizText(15).fill(result) 

私はあなたが意味を考える：

quizText: Array(15).fill(result)
