Json 如何显示包含对象详细信息的数组元素详细信息

我必须从.json文件中检索数据。在显示详细信息时，我无法显示数组中的对象详细信息

.json

---

在这里，我可以检索答案数组的详细信息，但无法显示正确的详细信息。有谁能建议显示细节的正确方法吗

你说的无法显示文本是什么意思？您能否显示有关如何访问此属性的代码？请尝试此变量correct=data.questions.level[0]。问题[0]。答案[2][\u correct]//要访问1级问题的正确属性，我们不应该每次都硬编码回答[2]。正确的ans可能并不总是2。它应该通过获取参数来显示。然后您可以循环通过answer对象来获得_Correct的位置，如var crt=null；$。eachanswer，functioni，elem{iftypeofelem==object{crt=elem[_correct]；}；
