小编jay*_*iya的帖子

我想以codeigniter Active Record的形式编写下面的mysql查询

select c.*
from code c
left join code_like l on c.id = l.code_id
group by c.id
order by count(*) desc

我正在尝试下面的查询,但如何添加 order by count(*) desc

        $this->db->select('*');
        $this->db->from('code');
        $this->db->join('code_like', 'code.id = code_like.id');
        $this->db->group_by("code.id"); 
        $query = $this->db->get();

如何在mouseout事件发生时停止time()？

jsfiddle链接:

`<div id="j" style="height:50px; width:50px; background-color:red;">Hello</div`>


$("#j").mouseenter(function(){
    var count = 3;
    var counterIncrement=1;
    setInterval(timer, 1000); 
    function timer() {
        count = count+counterIncrement;
        if (count == 3  ) {
            counterIncrement = +counterIncrement;
        }
         console.log(count);

    }
});

当mouseout再次出现时我想重置timer()函数mousein然后开始count = 3
