下面的代码有效。注意countdocuments的使用。
var mongoose = require('mongoose'); var db = mongoose.connect('mongodb://localhost/myApp'); var userSchema = new mongoose.Schema({name:String,password:String}); var userModel =db.model('userlists',userSchema); var anand = new userModel({ name: 'anand', password: 'abcd'}); anand.save(function (err, docs) { if (err) { console.log('Error'); } else { userModel.countdocuments({name: 'anand'}, function(err, c) {console.log('Count is ' + c); }); } });
