将数据保存到本地存储中的 json 文件中

Question

我在 Backbone 上开发了 HTML5 游戏。当您想使用编辑菜单和编辑世界时，它使用本地存储。您也可以使用此菜单更改您的角色。所以我想在游戏开始前添加角色选择，但我真的不知道如何将它插入到文件中。 文件如下所示：

3:"{"viewportBottom":0,"id":3,"tiles":[],"x":0,"y":0,"tileWidth":32,"tileHeight":32,"width":212,"height":17,"backgroundColor":"rgba(66, 66, 255, 1)","name":"level_1-1","sprites":[
{"name":"ground-ug","state":"idle","sequenceIndex":0,"x":32,"y":512},
{"name":"ground-ug","state":"idle","sequenceIndex":0,"x":0,"y":512},
{"name":"ground-ug","state":"idle","sequenceIndex":0,"x":64,"y":512},
{"name":"ground-ug","state":"idle","sequenceIndex":0,"x":128,"y":512},
{"name":"luigi","state":"idle-right","sequenceIndex":0,"x":192,"y":448,"velocity":0,"acceleration":0,"yVelocity":0,"yAcceleration":0}
],"savedOn":"2015-07-31T14:29:08.725Z","state":"play","viewportTop":0,"viewportRight":0,"viewportLeft":0,"time":748}"

例如，我想把 Luigi 换成马里奥，但我真的很菜鸟。

        <p id="Character" onclick="choose('mario')">Mario</p>

        <script>

            var character;
function choose(choice){
    character = choice;
}


            var parsed = JSON.parse(myJSONData, function(k, v) {
                    if (v === "mario") 
                        this.value = character;
                    else
                        return v;
                });
    }
        </script> 

顺便说一句，它不起作用：D 我也不知道如何将它存储到本地存储中。我正在查看文档，但我并不聪明：D 这个基于 Backbone 的游戏的文档：http://martindrapeau.github.io/backbone-game-engine/

有人能帮帮我吗？ :) 谢谢。

将某些内容存储到本地存储：

localStorage.variableName = 'value';

请注意，本地存储仅允许您使用 strings，因此存储 JSON 数据意味着执行 JSON.stringify(data)。

从本地存储中检索很简单：

var dataStr = localStorage.variableName;
