但我需要在页面的其他地方保留一些休息时间，
How would I remove the breaks from a divwith the id "grape1" and "grape12" but leave all others intact?
如何从divid 为“grape1”和“grape12”的a 中删除中断，但保留所有其他中断？

$('#grape1,#grape12').find('br').remove();
回答by Brombomb
$('br', '#grape1, #grape12').remove();?
The second argument in the $selector allows you to filter your search to a given subset, instead of the entire DOM. In this case we tell jQuery to only look inside the grape1and grape12divs. This will match all br's in those div's.
$选择器中的第二个参数允许您将搜索过滤到给定的子集，而不是整个 DOM。在这种情况下，我们告诉 jQuery 只查看grape1和grape12div内部。这将匹配那些 div 中的所有 br。

If that doesn't work (as happened in my case also) it's probably because the <br>are generated by some scripts after the JS .remove()code execution.
如果这不起作用（在我的情况下也发生过），可能是因为<br>JS.remove()代码执行后由某些脚本生成。
To check if I was right I set a quite long timeout and all my unwanted <br>disappeared after that time.
So, in the end I just decided to put a simple CSS
为了检查我是否正确，我设置了一个很长的超时时间，<br>在那之后我所有不需要的都消失了。所以，最后我决定放一个简单的 CSS
#grape1 br, #grape12 br {
display: none;
}
#grape1 br, #grape12 br {
display: none;
}
and eveybody's happy =)
并且每个人都很开心 =)
