Question

我首先在json中存储localstorage，然后再将其存储在最终json中，但我在最终backslash中获得额外json。我的代码是：

<!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>

我得到的输出是：

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

我错了，我得到了额外的backslash。如何删除额外的backslashes？附：我不想直接将变量mi存储在我的FinalJson中，因为它包含一些更复杂的值，为简单起见，我已将其删除。

Answer 1

它被串联两次

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

Answer 2

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);

存储在localstorage中时json中不需要的反斜杠
