下面是一个JSON字符串，在他们都说没关系，我想你会觉得这是个多余的问题，我理解。但我被卡住了，我对这个问题变得疯狂，无法自己解决它

因此，我以这种方式解析JSON字符串（底部的数据变量内容）：

我也试着像往常一样获取数据：

console.log(data.result); or console.log(data['result']);

但它总是

未定义的

。有人能帮我吗

以下是var数据的内容：

呃，如果这是它在控制台中打印的方式，那是无效的json。有效的json不需要转义双引号。如果这不是如果您只记录数据将记录到控制台的内容，请提供给我们。我也尝试过没有反斜杠，它在resultvar data=“{”result:“true”的r中返回一个无效字符..…未捕获的语法错误：位置3处JSON中的意外标记r您能更好地格式化您问题中的JSON吗？那不是真的。如果他在JS字符串之外编写JSON，那么这是可能的（尽管不是必需的）。由于他确实将其放在字符串中，并使用

var data = '{"result":"true","id":"31","content":"{"nested":"object"}","status":"0"}';
JSON.parse(data); // SyntaxError

var data = '{"result":"true","id":"31","content":{"nested":"object"},"status":"0"}';
JSON.parse(data); // success
