通过复选框检查多选题的答案，以显示正确答案角度

Question

我想通过检查复选框is_answer =1来检查答案是否正确并显示正确的单词，或者如果错误则显示错误

我在一个数组vm.quiz_multi_answer = []; vm.quiz_multi_answer.push();中返回答案，我希望循环选择，以便与is_answer比较选定的答案

vm.quiz_multi_data = [
    {
      question: "What does HTML stand for?",
      choices: [
        {
          id: "0",
          choice: "HyperText Markup Language",
          is_answer: "1"
        },
        {
          id: "1",
          choice: "HyperText Markup Language",
          is_answer: "1"
        },
        {
          id: "2",
          choice: "HyperText Markup Language",
          is_answer: "0"
        },
        {
          id: "3",
          choice: "HyperText Markup Language",
          is_answer: "0"
        }
      ]
    }
  ];

Answer 1

你可以像这样循环遍历

for(let i =0  ;i < quiz_multi_data.length ; i ++ ){
 if(quiz_multi_data[i].question/_id == "any_question_veriable"){
    for(let j =0 ; j < quiz_multi_data[i].choices[j].length ; j++ ){
           if( quiz_multi_data[i].choices[j]._id == id){
              //perform some logic 
            }
    }
}
