如何选择多个给定元素的子元素?
问题描述：
我有<div id='mydiv'>，我需要选择所有pre和div元素，它们是#mydiv的子元素.
I have <div id='mydiv'> and I need to select all pre and div elements that are children of #mydiv.
我可以这样:
div#mydiv > pre, div#mydiv > div
但是，可以做到只引用一次#mydiv吗?
but, can it be done so that #mydiv is referenced only once?
div#mydiv > pre, div
将选择页面上的所有div，无论它们是#mydiv的子级，因此逗号都不是实现此目的的方法.也许还有另一种我不知道的语法?
will select all divs on the page regardless if they're children of #mydiv, so the comma isn't a way to do it. Maybe there's another kind of syntax I don't know about?
答
您必须两次引用#mydiv ...
You'll have to reference #mydiv twice...
#mydiv > pre, #mydiv > div
由于ID足够具体，我删除了多余的div元素选择器.
I removed the extraneous div element selector as the ID is specific enough.
