Question

所以我只想将1个值存储在同一文件夹中的外部JSON文件中。每次我尝试获取该项时，chrome都会显示“意外令牌：”，它会显示另一个错误，指出JSON.parse（data）方法中的数据是错误的。无论哪种方式，无论有没有parse（），我都会得到令牌错误。它不喜欢"e1" :部分，json文件的该部分下面有一条红色错误行。我在这个网站和其他网站上看到了大约6条建议，但它对我的特定问题没有帮助。有什么想法吗？

这是我的代码：

<!DOCTYPE html>
<html>
<head>
    <title>Objects 2</title>
    <script type="text/javascript" src="data.json"></script>
</head>
<body>
    <div id="test"></div>
    <script>
        var extJSON = JSON.parse(data);
        document.getElementByID("test").innerHTML = extJSON.e1.position;
    </script>
</body>
</html>

这是我的JSON文件

{
    "e1" : 
    {
        "first_name" : "John",
        "last_name"  : "Smith",
        "age"        : 42,
        "position"   : "mechanic",
        "phone"      : 
        {
            "home"   : "718-111-1111",
            "mobile" : "718-222-2222",
            "work"   : "718-333-3333"
        }
    },
    "e2" :
    {
        "first_name" : "Jane",
        "last_name"  : "Smith",
        "age"        : 34,
        "position"   : "Investor",
        "phone"      : 
        {
            "home"   : "305-111-1111",
            "mobile" : "305-222-2222",
            "work"   : "305-333-3333"
        }
    },
    "e3" :
    {
        "first_name" : "Rusty",
        "last_name"  : "Colon",
        "age"        : 23,
        "position"   : "Diver",
        "phone"      : 
        {
            "home"   : "415-111-1111",
            "mobile" : "415-222-2222",
            "work"   : "415-333-3333"
        }
    },
    "e4" :
    {
        "first_name" : "Anna",
        "last_name"  : "Spencer",
        "age"        : 20,
        "position"   : "Event Planner",
        "phone"      : 
        {
            "home"   : "786-111-1111",
            "mobile"   : "786-222-2222",
            "work" : "786-333-3333"
        }
    }
}

我只想打印任何值或属性值对。感谢。

Answer 1

尝试更改脚本标记，如下所示：

<script id="data" type="application/json" src="data.json">

然后参考：

var extJSON = JSON.parse($("#data").html());

希望这有帮助。

请试试这个代码

 <!DOCTYPE html>
    <html>
    <head>
        <title>Objects 2</title>
        <script type="text/javascript" src="data.json"></script>
    </head>
    <body>
        <div id="test"></div>
        <script>
            var extJSON = data;
            document.getElementById("test").innerHTML = extJSON.e1.position;
// it is getElementById not getElementByID. it is case sensitive.
        </script>
    </body>
    </html>

根据您的代码data.json文件应该像

data= {
        "e1" : 
        {
            "first_name" : "John",
            "last_name"  : "Smith",
            "age"        : 42,
            "position"   : "mechanic",
            "phone"      : 
            {
                "home"   : "718-111-1111",
                "mobile" : "718-222-2222",
                "work"   : "718-333-3333"
            }
        },
        "e2" :
        {
            "first_name" : "Jane",
            "last_name"  : "Smith",
            "age"        : 34,
            "position"   : "Investor",
            "phone"      : 
            {
                "home"   : "305-111-1111",
                "mobile" : "305-222-2222",
                "work"   : "305-333-3333"
            }
        },
        "e3" :
        {
            "first_name" : "Rusty",
            "last_name"  : "Colon",
            "age"        : 23,
            "position"   : "Diver",
            "phone"      : 
            {
                "home"   : "415-111-1111",
                "mobile" : "415-222-2222",
                "work"   : "415-333-3333"
            }
        },
        "e4" :
        {
            "first_name" : "Anna",
            "last_name"  : "Spencer",
            "age"        : 20,
            "position"   : "Event Planner",
            "phone"      : 
            {
                "home"   : "786-111-1111",
                "mobile"   : "786-222-2222",
                "work" : "786-333-3333"
            }
        }
    };

希望它适合你。
