Javascript 无效的JSON-尝试嵌套数组

我正在尝试构建一个JSON对象来驱动我的web应用程序，但是我当前返回了一个无效的JSON对象，我看不到问题所在

我已经运行了JSON，我得到了以下错误

第19行的分析错误： ... ] },
----------------------^ 应为“STRING”、“NUMBER”、“NULL”、“TRUE”、“FALSE”、“{”、“[”

我的JSON对象在下面

    {
    "name": "FF",
    "good": {

        "doors" : [
            {
                "name" : "Door Name 1",

                    "Specifics 2a"
                ]   
            },

            }, //LINE 19 - Where the JSON Lint states there to be an error.
            {
                "name" : "Door Name 3",
                "thumb": "http://placehold.it/134x134/0000ff/ffffff",

            },

        "walls" : [

                    "Chair Rail A",
                ]   
            },

                "specifics" : [
                    "Panel Moulding A",
                    "4\" Rossette"
                ]   
            },
            {

                "specifics" : [
                    "Panel Moulding A",
                    "6\" Rossette"
                ]   
            },
        ],

    },
    "best": {},
    "better": {}
}

我假设问题来自于试图在对象中使用数组，这样我在循环时可以有多个选项，对吗？如果是，我的JSON应该如何形成？

数组项后有一个额外的逗号，就在这里：

    "specifics" : [
        "Specifics 1b",
        "Specifics 2b",
        "Specifics 3b", //there is no next element, remove the ,
    ]  

同样的情况也发生在这里：

    "specifics" : [
        "Chair Rail A",
    ]   

walls属性后还有一个额外的逗号：

"walls" : [
    {
        "name" : "Chair Rail A",
        "thumb": "http://placehold.it/134x134/0000ff/ffffff",
        "specifics" : [
            "Chair Rail A",
        ]   
    },
    {
        "name" : "Wall Paneling with Rosettes A",
        "thumb": "http://placehold.it/134x134/b4da55/ffffff",
        "specifics" : [
            "Panel Moulding A",
            "4\" Rossette"
        ]   
    },
    {
        "name" : "Wall Paneling with Rossettes B",
        "thumb": "http://placehold.it/134x134/ff0000/ffffff",
        "specifics" : [
            "Panel Moulding A",
            "6\" Rossette"
        ]   
    },
], //Remove me

在JSON中的许多地方都有悬空的逗号。去掉这些逗号，JSON将被解析。在这些情况下，我总是发现这是一个有用的工具。

这里的问题是JSON格式错误。以下是正确的格式：

{
"name": "FF",
"good": {

    "doors" : [
        {
            "name" : "Door Name 1",
            "thumb": "http://placehold.it/134x134/ff0000/ffffff",
            "specifics" : [
                 "Specifics 1a",
                "Specifics 2a"
            ]   
        },
        {
            "name" : "Door Name 2",
            "thumb": "http://placehold.it/134x134/b4da55/ffffff",
            "specifics" : [
                "Specifics 1b",
                "Specifics 2b",
                "Specifics 3b"
            ]   
        },
        {
            "name" : "Door Name 3",
            "thumb": "http://placehold.it/134x134/0000ff/ffffff",
            "specifics" : [
                 "Specifics 1c",
                "Specifics 2c",
                "Specifics 3c",
                "Specifics 4c"
            ]   
        }
    ],
    "walls" : [
        {
            "name" : "Chair Rail A",
            "thumb": "http://placehold.it/134x134/0000ff/ffffff",
            "specifics" : [
                "Chair Rail A"
            ]   
        },
        {
            "name" : "Wall Paneling with Rosettes A",
            "thumb": "http://placehold.it/134x134/b4da55/ffffff",
            "specifics" : [
                "Panel Moulding A",
                "4\" Rossette"
            ]   
        },
        {
            "name" : "Wall Paneling with Rossettes B",
            "thumb": "http://placehold.it/134x134/ff0000/ffffff",
            "specifics" : [
                "Panel Moulding A",
                "6\" Rossette"
            ]   
        }
    ]

},
"best": {},
"better": {}
}

您在json中使用了太多逗号

---

我用它来验证JSON，我发现它对于突出显示错误非常有用。

您的JSON格式无效，代码中有大量的

，

，请在线验证JSON代码

在线验证工具：

“Specifics 3b”，正如@MichaelKunst指出的那样，

。额外的逗号..删除它注意，虽然大多数JavaScript实现在对象或数组的末尾接受一个尾随逗号，但JSON比JavaScript更严格，尾随逗号被明确禁止。例如，

[“a”，]

是有效的JavaScript，但是

JSON.stringify（“[”a“，]”

）将失败（对于对象也是如此）。
