如何在jquery中的textarea之后附加HTML？

Question

我想在<{1}}之后（不在其中）附加一些html

即。变化

textarea

到

<textarea>content</textarea>

我可以附加到标题或div但是当我尝试使用textarea时它不会这样做。为什么呢？

HTML

<textarea>content</textarea>other_content

JS

<h1>Top</h1>
<h2> middle</h2>
<textarea>stuff</textarea>
<h3> h3</h3>

试试这个：

with cte as
(   
    select 
        *, 
        row_number() over ( partition by product order by date desc ) as rownumber
    from 
        saleslist
    where 
        datediff( month, date, getdate() ) < 2 
    )
    select 
        product, 
        ((max(case when rownumber = 1 then price end) - 
          max(case when rownumber = maxn then price)) /
          max(case when rownumber = maxn then price end)
       )
  from 
      (select cte.*, max(rownumber) over (partition by product) as maxn   
       from cte) 
group by product
