我想保持这个方法,直到数组有两个或更多使用nodejs和mongodb的元素。。
exports.Arrayelements = function(req, res) {
var elementName = req.body.elementName;
connection.arrayelements.updateMany({}, { $push: { sampleArray: [elementName] } }, { upsert: true });
connection.arrayelements.find({}, function(err, docs) {
if(err) throw err;
if(docs[0].elementName.length >= 2) {
// call this function
} else {
// want to call back again to push syntax until 2 or more elements in array
}
});
}
