拿過來的json數(shù)據(jù)如何重組數(shù)據(jù)按試題類型分類？

最后渲染到頁面是按單選、多選、判斷等進(jìn)行，求解？

心悲涼

你的意思是按.question.questionType分揀？

假設(shè)你給的數(shù)組存在一個變量questions里，分揀完存對象collection里

var collection = {};

questions.forEach(ques => (collection[ques.question.questionType] = collection[ques.question.questionType] || []).push(ques));

分開寫看得清楚點

var collection = {};

questions.forEach(ques => {
  collection[ques.question.questionType] = collection[ques.question.questionType] || [];
  collection[ques.question.questionType].push(ques);
});
