我的浏览器（chrome）似乎不喜欢我的 JSON（通过 ASP.NET 的 return Json(object) 格式化）。

我失败的 JavaScript 处理程序如下所示：

var responseObj = JSON.parse(msg);

在我解析它之前，我可以看到 chrome JavaScript 调试器中的所有内容，但是当我将它发送到 JSON.parse() 时它失败了。

真正奇怪的是 JSONLint 说它是有效的。

我的 JSON 看起来像这样（实际对象要长得多，信不信由你）：

JSON.parse用于将 JSON 字符串解析为 JavaScript 对象。

如果您尝试解析一个对象（这是您在问题中发布的内容），您将在 Chrome 中收到“意外令牌”消息。

所以，要么你试图转换不需要转换的东西，要么你想把一个对象转换成 JSON，在这种情况下你需要stringify

没有看到你的代码，很难说发生了什么，但你的 JSON 很好：

现在，如果您尝试在 Javascript 编码中使用它，那么您不应该使用 JSON，而应该只分配一个对象。不需要解析，编译器会为您完成。

换句话说——不要做我刚才做的事。我只是用它来表明它可以在 Chrome (21.0.1180.57) 下正确解析为 JSON

在构建带有融合表的应用程序时，我遇到了同样的错误。谷歌的回复没有被正确解析。我用json2.js替换了原生的 json 库，问题就解决了。

我通过简单的 JSON 尝试遇到了这个问题（使用 Chrome）：

var TOC = { id: 1, title: "header" }

$.parseJSON 给出了同样的错误。

我发现的解决方法是将它包含在一个数组中（然后引用索引零）。

var TOC = [{ id: 1, title: "header" }][0]
