Node JS remove a specific object from array (mongoose)-CodePudding

I have an array of objects - lists[]; and an object - obj;

This is the lists array:

{
  _id: new ObjectId("61840c5ce237f22a1c7a1ac7"),
  name: 'list1',
  content: [ 'aaaa' ],
  description: 'aa',
  tags: [],
  lastmodified: 1,
  __v: 0
},{
  _id: new ObjectId("61840def80a88d1b2ffce400"),
  name: 'list',
  content: [ 'list!' ],
  description: 'test',
  tags: [],
  __v: 0
}

and this is the obj object:

{
  _id: new ObjectId("61840def80a88d1b2ffce400"),
  name: 'list',
  content: [ 'list!' ],
  description: 'test',
  tags: [],
  __v: 0
}

Simple Question: How do I delete the object from "lists", similar to the "obj" one

CodePudding user response：

You could use JavaScript Array.filter() method to exclude the target object from the list:

const list = [{
_id: new ObjectId("61840c5ce237f22a1c7a1ac7"),
  name: 'list1',
  content: [ 'aaaa' ],
  description: 'aa',
  tags: [],
  lastmodified: 1,
  __v: 0
},{
  _id: new ObjectId("61840def80a88d1b2ffce400"),
  name: 'list',
  content: [ 'list!' ],
  description: 'test',
  tags: [],
  __v: 0
}];

const targetObj = {
  _id: new ObjectId("61840def80a88d1b2ffce400"),
  name: 'list',
  content: [ 'list!' ],
  description: 'test',
  tags: [],
  __v: 0
};

const filteredList = list.filter((element) => element._id !== targetObj._id);

use some sort of filtering... heres an idea.

items = [{
  _id: new ObjectId("61840c5ce237f22a1c7a1ac7"),
  name: 'list1',
  content: [ 'aaaa' ],
  description: 'aa',
  tags: [],
  lastmodified: 1,
  __v: 0
},{
  _id: new ObjectId("61840def80a88d1b2ffce400"),
  name: 'list',
  content: [ 'list!' ],
  description: 'test',
  tags: [],
  __v: 0
}]

removeID = "61840def80a88d1b2ffce400"

items = [item for item in items if item['id'] != removeID]
