Question

我有id和i用这些过滤多维数组。我的代码是：

 service.fakedata.map(f=>{
          f.results.map(r=>{
             r = r.filter(m=> m.rId !== id)
          })
 })

我的数组是：

"services": [
    {
        "id": "1839f72e-fa73-47de-b119-49fb971a5730",

                ],
                "inputParams": [
                    {
                        "iId":"e74a6229-4c08-43a1-961f-abeb887fa90e",
                        "key": "in1",

                    },
                    {
                        "iId":"e74a6229-4c08-43a1-961f-abeb887fa90o",

                    }
                ],
                "results": [
                    {
                        "rId": "ef7c98db-9f12-45a8-b3fb-7d09a82abe3d",
                        "key": "out1",
                        "value": "result1",
                        "fakedatatype": [
                            "address",
                            "city"
                        ]
                    },
                    {
                        "rId": "9b178ded-af27-43df-920f-daab5ad439b9",
                        "key": "out2",
                        "value": "result2",
                        "fakedatatype": [
                            "internet",
                            "url"
                        ]
                    }
                ]
            }
        ]
    }
]

在这种情况下，过滤器正在运行（当我使用console.log检查时），但它没有更改fakedata数组。

我的代码出了什么问题？

来自https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/map

map（）方法创建一个新数组，其结果是在调用数组中的每个元素上调用提供的函数。

基于@ H77建议我改变了我的代码，现在我的代码看起来像这样，一切都运行良好
