Question

当我在删除ID后导入json数据时，我的导入功能可以正常工作。但是，如果我使用自己的ID导入数据，则控制台会显示数据未定义。

    [
    {
    "data" : "abc",
    "parent" : null,
    "type" : "Organization",
    "parentType" : null,
    "API" : "",
    "value" : "abc",
    "filename" : "uploads.wsdl",
    "company" : "comapany"
    },
    {
    "data" : "def",
    "parent" : "abc",
    "type" : "Department",
    "parentType" : "Organization",
    "API" : "",
    "value" : "def",
    "filename" : "uploads.wsdl",
    "company" : "company"
    }
    ]

        d3.json("marvel.json", function(error, mydata) {
    console.log(mydata)
    });

上面的代码工作正常。

    [
    {
    "_id" : ObjectId("5d2d862a68a6bc22a9e99046"),
    "data" : "abc",
    "parent" : null,
    "type" : "Organization",
    "parentType" : null,
    "API" : "",
    "value" : "abc",
    "filename" : "uploads.wsdl",
    "company" : "company"
    },
    {
    "_id" : ObjectId("5d2d862a68a6bc22a9e99047"),
    "data" : "def",
    "parent" : "abc",
    "type" : "Department",
    "parentType" : "Organization",
    "API" : "",
    "value" : "def",
    "filename" : "uploads.wsdl",
    "company" : "comapny"
    }
    ]
        d3.json("marvel.json", function(error, mydata) {
    console.log(mydata)
    });

在此代码中，mydata未定义

Answer 1

此：

{"_id" : ObjectId("5d2d862a68a6bc22a9e99047")}

无效的JSON，函数调用或对象初始化不是JSON规范的一部分，失败将在任何理智的JSON解析器下失败。

D3无法导入具有数据中指定的自定义ID的JSON数据
