JSON.parse 関数と eval 関数の両方でエラーが発生しています。http://jsonlint.com/を使用して JSON を検証しました。 

<script type="text/javascript">

引用符を適切にエスケープしていないため、別のバックスラッシュが必要です。

これは間違っています;

JSON.parse('{ "fails" : "\"http://\" or \"https://\"" }')

このようにする必要があります。

JSON.parse('{ "passes" : "\\"http://\\" or \\"https://\\"" }')

何かが有効な JSON である場合、基本的には次のように記述できることを意味します。

var xx = <that-thing-you-validated>;

ただし、JSON.parse()同じではない JSON 形式の文字列が必要です。観察：

var yy = {text: "hello \"world\""};
console.log(JSON.stringify(yy));
// output: "{"text":"hello \"world\""}"

では、それをコピーして貼り付け、外側の二重引用符を単一引用符に置き換えましょう (内部の二重引用符をエスケープしたくないため)。

console.log('{"text":"hello \"world\""}');
// output: {"text":"hello "world""}

うわー、バックスラッシュはどうしたの?! バックスラッシュを含む JavaScript で文字列リテラルを作成するには、これもエスケープする必要があります。

console.log('{"text":"hello \\"world\\""}');
// output: {"text":"hello \"world\""}

今はうまくいきますか？

JSON.parse('{"text":"hello \\"world\\""}');
// output: Object

はい！:)
