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);
});
