"content" : "11 : 0", 
"cause" : "nothing", 
"_id" : ObjectId("591849164fb23515c0e80b53") }`


my request :

      Employer.update({"agenda._id" :req.params.subid,
        "agenda.margetime._id" :req.params.subsubid},
        {"$set": {"agenda.$.margetime.$": req.body}}, function (err,data) {
        res.jsonp(data);
        })});

Answer 1

不幸的是，mongo仅支持单级阵列更新。如果已知数组内的数组索引，$将对您有所帮助。你可以使用这样的东西 -

> Employer.update({"agenda._id" :req.params.subid,
        "agenda.margetime._id" :req.params.subsubid}, {$set:{"agenda.0.margetime.1":req.body}});

在提出问题之前你应该读过这些 - Update embedded object inside array inside array in MongoDB

Updating nested array inside array mongodb

Answer 2

非常感谢mAky_0788先生的帮助，这是我的问题的解决方案：

    Employer.findById(req.params.employerId, function (e, data) {
        if (e) console.log(e);
        var t = data.agenda.id(req.params.subid).margetime.id(req.params.subsubid);
        t.content = req.body.content;
        t.value = req.body.value;
        t.cause = req.body.cause
        data.save();
 res.jsonp(t)
    });
