用特定引号内的\\ quotes替换所有出现的引号

Question

I have a string as below:

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

I want to replace " by \\" , which is only inside body value

This means the string should become

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

It is better if the solution is done using regex.

My motive behind is to make it as a valid JSON so that after parsing I can get array of objects with keys as body and value as string.

Answer 2

Some thing try as follow

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);
