如何通过id从variants数组中获取currentUserAnswerVariants值文本？
My array请问您能看到这张图片吗，我的数组在哪里，当我检查某个变体时，我有了新的数组Answer array

Answer 1

function idEquals(idToCompare, question) {
    return question.id.indexOf(idToCompare) === 0;
}

currentUserAnswerVariantsVariantIds = question.filter(idEquals.bind(this, currentUserAnswerVariants));

这有效吗？遵循这些原则，您可以相应地编辑以下代码。

Answer 2

$ var = $（'＃id'）。val（）;
$ var ['text']; ->仅在需要单个ID文本的情况下

->或在id上使用foreach并将每个结果推入一个空白数组并打印数组
