<code>{
    id:1,
    username:'test',
    list:
    [
        {
            name:'t1'
        },
        {
           name:'t2'
        }
    ]
}

可以直接获取list分段查询吗?
比如一页显示一条,第一页显示[{name:'t1'}] 第二页显示[{name:'t2'}],这样子

回复内容:

<code>{
    id:1,
    username:'test',
    list:
    [
        {
            name:'t1'
        },
        {
           name:'t2'
        }
    ]
}

可以用MongoDB的聚合框架

db.test.aggregate([ {$match: {id:1}},  {$unwind: "$list"}, {$sort:{'list.name':1}}, {$skip:5}, {$limit: 5}]);   // 取得list下面从第6个到第10个
Copy after login

你想问什么。。。。
