mongodb中的游标使用
mongodb中的游标使用假设:db.XXX.remove();db.XXX.insert({"name":"BuleRiver1", "age":27});db.XXX.insert({"name":"BuleRiver2", "age":23});db.XXX.insert({"name":"BuleRiver3", "age":21});find()返回一个游标:var cursor = db.XXX.find();while (cursor.hasNext()) {obj = cursor.next();print(obj.name);}使用游标的forEach():cursor.forEach(function(x) {print(x.name);});
