用特定引號內的\\ quotes替換所有出現的引號

Question

我有一個字符串如下：

var tst ='[{"body":"Hi Akhil station siate "U" turjunction,- Immedia"},'
         +'{"body":"Hiate "dgt" turjunction,- Immedia"},'
         +'{"body":"Hiate "sd turjunction,- Immedia"}]';

我想更換“的\\”，這是唯一的體內值

這意味着字符串應該變成

'[{"body":"Hi Akhil station siate \"U\" turjunction,- Immedia"},'
             +'{"body":"Hiate \"dgt\" turjunction,- Immedia"},'
             +'{"body":"Hiate \"sd turjunction,- Immedia"}]'

如果使用正則表達式來解決，則更好。

我背后的動機是使其成為有效的JSON，以便在解析之后，我可以獲得鍵為主體 ，值為字符串的對象數組。

Answer 1

讓Javascript引擎為您完成工作。

var x = JSON.stringify( tst );

Answer 2

一些事情嘗試如下

var tst ='{"body":"Hi Akhil station siate "U" turjunction,- Immedia"},'
     +'{"body":"Hiate "dgt" turjunction,- Immedia"},'
     +'{"body":"Hiate "sd turjunction,- Immedia"}';

    tst = tst.replace(/\s("[^"]+?")(?!\})|\s"([^ ]+)/g,function($1)
    {
        if($1.match(/".+"/))
        {
            return $1.replace(/"/g,"\\\"");
        }
        else
        {
            return $1.replace(/"/g,"\\\"");
        }
     });


console.log(tst);
