How to filter array in object by few conditions

问题

以下是代码的翻译部分：

  1. 我有这样一个具有newComments属性的对象：
  3. const newComments = {
  4.   commentDirectoryId: "ee63997c-01d5-ec11-8dad-e116bd673e14",
  5.   comments: [
  6.     {
  7.       id: "123",
  8.       status: {
  9.         entity: null,
  10.         id: "1a913152-7809-ec11-8daa-90600b960f93",
  11.         name: "In work",
  12.         parentId: null,
  13.       },
  14.     },
  15.     {
  16.       id: "124",
  17.       status: {
  18.         entity: null,
  19.         id: "1a913152-7809-ec11-8daa-90600b960f94",
  20.         name: "Note",
  21.         parentId: null,
  22.       },
  23.     },
  24.     {
  25.       id: "125",
  26.       status: {
  27.         entity: null,
  28.         id: "1a913152-7809-ec11-8daa-90600b960f95",
  29.         name: "Canceled",
  30.         parentId: null,
  31.       },
  32.     },
  33.     {
  34.       id: "126",
  35.       status: {
  36.         entity: null,
  37.         id: "1a913152-7809-ec11-8daa-90600b960f96",
  38.         name: "Done",
  39.         parentId: null,
  40.       },
  41.     },
  42.   ],
  43.   dataType: "Tags",
  44.   idAttributeApprovalName: "12-015-123",
  45. };

还有筛选条件：

  1. const values = ["Note", "Canceled", "Done"];

我的任务是返回与这些键不相等的评论：

  1. comment.status.name !== "Note" | "Canceled" | "Done"

换句话说：

  1. const newComments = {
  2.   commentDirectoryId: "ee63997c-01d5-ec11-8dad-e116bd673e14",
  3.   comments: [
  4.     {
  5.       id: "123",
  6.       status: {
  7.         entity: null,
  8.         id: "1a913152-7809-ec11-8daa-90600b960f93",
  9.         name: "In work",
  10.         parentId: null,
  11.       },
  12.     },
  13.   ],
  14.   dataType: "Tags",
  15.   idAttributeApprovalName: "12-015-123",
  16. };
英文:

I have such an object with newComments:

  1. const newComments = {
  2.   commentDirectoryId: "ee63997c-01d5-ec11-8dad-e116bd673e14",
  3.   comments: [
  4.     {
  5.       id: "123",
  6.       status: {
  7.         entity: null,
  8.         id: "1a913152-7809-ec11-8daa-90600b960f93",
  9.         name: "In work",
  10.         parentId: null,
  11.       },
  12.     },
  13.     {
  14.       id: "124",
  15.       status: {
  16.         entity: null,
  17.         id: "1a913152-7809-ec11-8daa-90600b960f94",
  18.         name: "Note",
  19.         parentId: null,
  20.       },
  21.     },
  22.     {
  23.       id: "125",
  24.       status: {
  25.         entity: null,
  26.         id: "1a913152-7809-ec11-8daa-90600b960f95",
  27.         name: "Canceled",
  28.         parentId: null,
  29.       },
  30.     },
  31.     {
  32.       id: "126",
  33.       status: {
  34.         entity: null,
  35.         id: "1a913152-7809-ec11-8daa-90600b960f96",
  36.         name: "Done",
  37.         parentId: null,
  38.       },
  39.     },
  40.   ],
  41.   dataType: "Tags",
  42.   idAttributeApprovalName: "12-015-123",
  43. };

There are also filters:

  1. const values = ["Note", "Canceled", "Done"];

My task is to return only comments that are not equal to keys:

  1. comment.status.name !== "Note" | "Canceled" |"Done"

In other words:

  1. const newComments = {
  2.   commentDirectoryId: "ee63997c-01d5-ec11-8dad-e116bd673e14",
  3.   comments: [
  4.     {
  5.       id: "123",
  6.       status: {
  7.         entity: null,
  8.         id: "1a913152-7809-ec11-8daa-90600b960f93",
  9.         name: "In work",
  10.         parentId: null,
  11.       },
  12.     },
  13.   ],
  14.   dataType: "Tags",
  15.   idAttributeApprovalName: "12-015-123",
  16. };

你可以使用 Array#filter 与 Array#every 或 Array#includes 结合使用。

  1. const newComments = {
  2.   commentDirectoryId: "ee63997c-01d5-ec11-8dad-e116bd673e14",
  3.   comments: [
  4.     { id: "123", status: { entity: null, id: "1a913152-7809-ec11-8daa-90600b960f93", name: "In work", parentId: null } },
  5.     { id: "124", status: { entity: null, id: "1a913152-7809-ec11-8daa-90600b960f94", name: "Note", parentId: null } },
  6.     { id: "125", status: { entity: null, id: "1a913152-7809-ec11-8daa-90600b960f95", name: "Canceled", parentId: null } },
  7.     { id: "126", status: { entity: null, id: "1a913152-7809-ec11-8daa-90600b960f96", name: "Done", parentId: null } },
  8.   ],
  9.   dataType: "Tags",
  10.   idAttributeApprovalName: "12-015-123"
  11. };
  13. const values = ["Note", "Canceled", "Done"];
  15. newComments.comments = newComments.comments.filter(c => 
  16.   values.every(v => c.status.name !== v));
  17. // 或者使用 !values.includes(c.status.name) 如果不需要复杂的匹配逻辑
  19. console.log(newComments);

请注意，以上代码片段是用JavaScript编写的，只提供代码部分的翻译。

英文:

You can use Array#filter in conjunction with Array#every or Array#includes.

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

  1. const newComments={commentDirectoryId:&quot;ee63997c-01d5-ec11-8dad-e116bd673e14&quot;,comments:[{id:&quot;123&quot;,status:{entity:null,id:&quot;1a913152-7809-ec11-8daa-90600b960f93&quot;,name:&quot;In work&quot;,parentId:null}},{id:&quot;124&quot;,status:{entity:null,id:&quot;1a913152-7809-ec11-8daa-90600b960f94&quot;,name:&quot;Note&quot;,parentId:null}},{id:&quot;125&quot;,status:{entity:null,id:&quot;1a913152-7809-ec11-8daa-90600b960f95&quot;,name:&quot;Canceled&quot;,parentId:null}},{id:&quot;126&quot;,status:{entity:null,id:&quot;1a913152-7809-ec11-8daa-90600b960f96&quot;,name:&quot;Done&quot;,parentId:null}},],dataType:&quot;Tags&quot;,idAttributeApprovalName:&quot;12-015-123&quot;};
  2. const values = [&quot;Note&quot;, &quot;Canceled&quot;, &quot;Done&quot;];
  3. newComments.comments = newComments.comments.filter(c =&gt; 
  4.                         values.every(v =&gt; c.status.name !== v));
  5. // or !values.includes(c.status.name) if no complex matching logic is required
  6. console.log(newComments);

<!-- end snippet -->
