I need to hide all this div but not the first div.
我需要隐藏所有这些 div 但不是第一个 div。
I could do something like this:
我可以做这样的事情:
jQuery('.box').hide();
jQuery('.box').first().show();
Is there a way to remove the first .box
from the array before .hide()
em?
有没有办法.box
在.hide()
em之前从数组中删除第一个?

比较:
@T.J.Crowder is right the code i have suggested does the extra parsing that can be avoided by .slice
as suggested by @zch
@TJCrowder 是正确的,我建议的代码执行了.slice
@zch 建议的可以避免的额外解析
HEREis the profile of my code (0.8ms)and HEREis the profile of @zch's code (0.53ms)see the difference
