如何更新数组对象中的项目

Question

我有一个架构

var card = new Schema({
id: Schema.Types.ObjectId,
    tenthe: String,
    mota: String,
    nhan: String,
    thanhvien: [Schema.Types.ObjectId],
    ngayKT: Date,
    checklist: [{
        seq: Number,
        tieude: String,
        list: [{
            noidung: String,
            trangthai: Number,
            seq: Number
        }]
    }],
    dinhkem: [String],
    binhluan: [{
        hoten: String,
        noidung: String,
        thoigian: Date,
        user: Schema.Types.ObjectId,
        seq: Number
    }],
    seq: Number

})

我要更新trangthai字段

 card.update({ 'checklist.list.seq': req.body.seql }, { $set: { "checklist.$.list": [{'trangthai': 1}], 'checklist.$.tieude': "aba" } }, (err, suc) => {
            console.log(err);
            console.log(suc);
            res.json(suc);
        })
