I am storing a json first in localstorage and then again storing it in final json but I am getting extra backslash in my final json. My code is:

<!DOCTYPE html>
<html>
<body>

 <script>

    var mi = [{
       "name": "Alex",
       "address": "abc"
       },
       {
        "name": "George",
       "address": "efg"
      }
      ]

    localStorage.setItem("myData", JSON.stringify(mi))

    var FinalJson = {
             "Collected values" : localStorage.getItem("myData"),
             "Place" : "washington"
            };
    document.write(JSON.stringify(FinalJson));
   </script>

</body>
</html>

Output I am getting is:

     {"Collected values":"[{\"name\":\"Alex\",\"address\":\"abc\"} {\"name\":\"George\",\"address\":\"efg\"}]","Place":"washington"}

Where am i going wrong that I am getting this extra backslash. How can I remove the extra backslashes? P.S. I don't want to directly store the variable mi in my FinalJson, as it contains some more plicated values which I have removed here for simplicity.

  • It's just escaping the string, try parsing the data back and see if it resolves it self, as you're probably not planning on just throwing the JSON out on the page as a string ? – adeneo Commented Jan 12, 2014 at 21:01
  • 1 Oh, it's double stringified, do "Collected values" : JSON.parse(localStorage.getItem("myData")) – adeneo Commented Jan 12, 2014 at 21:02

Reset to default 4

It's stringified twice

var FinalJson = {
     "Collected values" : JSON.parse(localStorage.getItem("myData")),
     "Place" : "washington"
};

http://jsfiddle/Kh5Br/

var mi = [{
     "name": "Alex",
     "address": "abc"
   },
   {
     "name": "George",
     "address": "efg"
   }
];

localStorage.setItem("myData", JSON.stringify(mi))

var tes = JSON.parse(localStorage.getItem("myData")); //It was "work". I thougt you missed that

var FinalJson = {
         "Collected values" : tes,
         "Place" : "washington"
        };
document.write(JSON.stringify(FinalJson));
document.write(tes);
