Question

我使用nodejs进行服务器端连接，我在下面发布了json对象，我想根据某些条件将json插入mongo

这是我的json：

"_id" : ObjectId("5a1507f7c6e9dc046ee76b01"),
    "sendStatus" : false,
    "draftName" : "ifelse",
    "draftData" : {
        "sms" : {
            "message" : "Sample",
            "sender" : "ifelse"
        },
        "contacts" : [
            {
                "selected" : true,
                "updatedAt" : "2017-11-18T06:17:32.000Z",

    "updatedOn" : ISODate("2017-11-22T05:15:35.423Z"),
    "__v" : 0

我将此数据插入mongodb，但我想设置一个条件，

我想只插入联系人：[{selected：true}]，其中包含所选的键：true，如果选择了对象键：false，我不想将该数据插入mongodb，帮帮我。

这是我的后端代码：

exports.addContactDraft = function (req, res) {
    console.log('contactttttttttt', req.body);
    var newContactDraft = req.body;
    newContactDraft.createdOn = new Date();
    newContactDraft.updatedOn = new Date();
    new Draft(newContactDraft).save(function (err, data) {
        if (err) console.log('new  err:', err);
        else res.status(200).send(data);
    });
}

假设您只想过滤掉联系人中的元素。您可以使用array.filter（）轻松地从contacts数组中过滤掉不需要的对象。

查看以下代码。

var data = {your json object stuff....}
 //Filter out the contacts with 'selected=false'

 data.draftData.contacts = 
data.draftData.contacts.filter(contact=>contact.selected===true);

//Modified contacts that include only the objects with selected property equal to true.

console.log(data);

使用nodejs将对象的特定值插入mongodb
