私のブラウザ（chrome）は私のJSON（ASP.NETの戻り値Json（object）を介してフォーマットされた）を好まないようです。

失敗するJavaScriptハンドラーは次のようになります。

var responseObj = JSON.parse(msg);

解析する前に、Chrome JavaScriptデバッガーですべてのコンテンツを確認できますが、JSON.parse（）に送信すると失敗します。

本当に奇妙なことは、JSONLintがそれが有効であると言ったことです。

私のJSONは次のようになります（実際のオブジェクトは、信じられないかもしれませんが）：

JSON.parseJSON 文字列を JavaScript オブジェクトに解析するためのものです。

オブジェクト（質問に投稿したもの）を解析しようとすると、Chrome で「予期しないトークン」メッセージが表示されます。

したがって、変換する必要のないものを変換しようとするか、オブジェクトを JSON に変換する必要があります。stringify

コードを見ないと何が起こっているのかわかりませんが、JSON は問題ありません。

これを Javascript コーディングで使用しようとしている場合は、JSON を使用するべきではなく、オブジェクトを割り当てる必要があります。構文解析は必要ありません。コンパイラがそれを行います。

言い換えれば、私がしたことをしないでください。JSONとしてChrome（21.0.1180.57）で正しく解析されることを示すために使用しています

フュージョン テーブルを使用してアプリをビルドするときに、同じエラーが発生しました。Google からの応答が正しく解析されていませんでした。ネイティブ json ライブラリをjson2.jsに置き換えたところ、問題は解決しました。

簡単な JSON 試行で (Chrome で) この問題に遭遇しました:

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

$.parseJSON で同じエラーが発生しました。

私が見つけた回避策は、それを配列で囲むことです (そして、インデックス 0 を参照します)。

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