MongoDb,如何根据某个_id值删除数据

Question

根据自带_id值删除老有问题，
javascript collection.remove({_id: ObjectId(id)}, {w:1}, function (err) { db.close() callback(err) })
提示ObjectId未定义，直接写_id：id 删不掉，id为一个字符串

Answer 1

Read the readme document of the official module,
Need to first var ObjectID = require('mongodb').ObjectID;
Then use collection.findAndRemove({_id: new ObjectID(id)}) to do this

Answer 2

db.collection.remove({"_id":ObjectId(id)});

Answer 3

If the id is a string, you can do this directly

db.collection.remove({"_id":"你的id"});
