Bing Search API からの json 結果を使用しています。結果として、二重引用符は 1 つのバックスラッシュでエスケープされます。ただし、Javascript はこれを受け入れません。二重バックスラッシュを使用して二重引用符をエスケープする必要があります。それで、私の質問は、単一のバックスラッシュを二重のバックスラッシュに置き換える方法です。たとえば、json コードの一部は次のようになります。

"Description":"LONDON Britain should stay in the EU \"warts and all\", the opposition Labour leader will say on Thursday..."

私はそれがこのようであることを望みます

"Description":"LONDON Britain should stay in the EU \\"warts and all\\", the opposition Labour leader will say on Thursday..."

次の解決策を試しました

json = '"Description":"LONDON Britain should stay in the EU \"warts and all\", the opposition Labour leader will say on Thursday..."';
dfe = JSON.stringify(json);
dfe = dfe.replace(/\\"/g,'\\\\"');

しかし、うまくいきませんでした。すべての二重引用符の前にあるすべてのバックスラッシュを置き換えました。これから行った...

\"Description\":\"LONDON Britain should stay in the EU \"warts and all\", the opposition Labour leader will say on Thursday...\"

...ここまで

\\"Description\\":\\"LONDON Britain should stay in the EU \\"warts and all\\", the opposition Labour leader will say on Thursday...\\"

\" を \\" に置き換える方法を教えてもらえますか?

var json = '{"d":{"results":[{"__metadata":{"uri":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/v1/News?Query=\u0027britain\u0027&$skip=1&$top=1","type":"NewsResult"},"ID":"f1c27ae7-bf16-4741-a789-897f4878c2e1","Title":"Britain should stay in EU \u0027warts and all\u0027 - Corbyn | Reuters","Url":"http://www.firstpost.com/world/britain-should-stay-in-eu-warts-and-all-corbyn-reuters-2728514.html","Source":"Firstpost","Description":"LONDON Britain should stay in the EU \"warts and all\", the opposition Labour leader will say on Thursday, making his first big intervention in the referendum campaign as he seeks to counter criticism he is not doing enough to persuade his voters to back the ...","Date":"2016-04-14T05:10:45Z"}],"__next":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/v1/News?Query=\u0027britain\u0027&$skip=10&$top=10"}}';

obj = JSON.parse(json);

これを試して：

var json = {"d":{"results":[{"__metadata":{"uri":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/v1/News?Query=\u0027britain\u0027&$skip=1&$top=1","type":"NewsResult"},"ID":"f1c27ae7-bf16-4741-a789-897f4878c2e1","Title":"Britain should stay in EU \u0027warts and all\u0027 - Corbyn | Reuters","Url":"http://www.firstpost.com/world/britain-should-stay-in-eu-warts-and-all-corbyn-reuters-2728514.html","Source":"Firstpost","Description":"LONDON Britain should stay in the EU \"warts and all\", the opposition Labour leader will say on Thursday, making his first big intervention in the referendum campaign as he seeks to counter criticism he is not doing enough to persuade his voters to back the ...","Date":"2016-04-14T05:10:45Z"}],"__next":"https://api.datamarket.azure.com/Data.ashx/Bing/Search/v1/News?Query=\u0027britain\u0027&$skip=10&$top=10"}};

JSONオブジェクトになります。
