Question

我正在使用Bing Search API的json结果。在结果中，双引号由单个反斜杠转义。但是Javascript不接受这个。它需要我使用双反斜杠来避开双引号。所以，我的问题是如何用双反斜杠替换单反斜杠。例如，json代码的一部分就像这样

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

我希望它像这样

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

我尝试了以下解决方案

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,'\\\\"');

然而，它没有用。它在所有双引号之前替换了所有反斜杠。它离开了......

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

...到此

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

有人能告诉我如何用“\\”代替吗？

编辑：我想做的是这个

<p id="demo"></p>
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);
document.getElementById("demo").innerHTML = obj.d.results[0].Title;

Answer 1

这个怎么样？

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

Answer 2

而不是

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);

试试这个：

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"}};

它将是JSON对象。
