我想更新mongodb嵌套数组中的字段

这是我的文档：

{
"_id": {
    "$oid": "5eb5f0a9d985888edb0523b0"
},
"subs": [{
    "name": "list1",
    "count": "0"
}, {
    "name": "list2",
    "count": "0"
}, {
    "name": "list3",
    "count": "0"
}, {
    "name": "list4",
    "count": "0"
}]
}

我目前正在使用mongojs。我希望能够例如找到“ list2”并增加与其关联的计数。我整天都在尝试，似乎无法解决。

任何帮助或指导将不胜感激！

我希望这会对您有所帮助。我使用编程方法来解决您的问题。

let payload = {
"_id": {
    "$oid": "5eb5f0a9d985888edb0523b0"
},
"subs": [{
    "name": "list1",
    "count": "0"
}, {
    "name": "list2",
    "count": "0"
}, {
    "name": "list3",
    "count": "0"
}, {
    "name": "list4",
    "count": "0"
}]
}

let fields = ["list2","list4"];

fields.forEach((element)=>{
    for(let i=0; i<payload.subs.length; i++){
         if(element===payload.subs[i]["name"]){
            let value = parseInt(payload.subs[i]["count"]);
            payload.subs[i]["count"] = (++value).toString();
         }
    }
})

console.log(payload.subs)
