json存储了一些职位信息，怎么根据mark的值，对这些信息进行分组 ，例如mark值为group：1的放到一个分组里，，mark值为group：2的放到一个分组里，然后在前端显示在不同模块里。该怎么对数据进行遍历？遍历之后怎么根据不同的mark值放到不同的数组里呢

<code>    public static function buildList($module){
        $jobList2 = "";

就是根据不同的group的值，让数据显示在相应的模块下面

var map = {};
for(var i=0,l=jobs.length;i var key = jobs[i]['mark'];
map[key] = map[key] || (map[key] = []);
map[key].push(jobs[i]);
}
return map;
这样返回的map就是一个key,value
{
group1:[job1,job2],
group2:[job3,job4]
}
应该就是你想要的

循环jobs数组：

<code>var jobsSortObject = {}; 
for(var i =0; i</code>
登录后复制

jobsSortObject就会是这个样子：

<code>{
    'group:1' : [{} , {}, {}],
    'group:2' : [ {} ]
}
</code>
