How to write a jQuery selector with multiple :eq's in single expression?
提问by thiesdiggity
I have a quick question. How do I write a jQuery selector expression with multiple :eq() selectors? I want to go down the DOM tree but every hope isn't uniform. Here is what I have that works:
我有一个快速的问题。如何编写带有多个 :eq() 选择器的 jQuery 选择器表达式?我想沿着 DOM 树向下走,但每个希望都不尽相同。这是我所拥有的:
$('div:eq(0)').find('div:eq(1)').find('div:eq(5)')
But is the following does not work:
但是以下不起作用:
$('div:eq(0) div:eq(1) div:eq(5)')
Is there a more elegant way to write it without all the "find"'s?
在没有所有“查找”的情况下,是否有更优雅的方式来编写它?

I believe that you could do the following and it should return all dom elements that match:
我相信您可以执行以下操作,它应该返回所有匹配的 dom 元素:
$('div:eq(0), div:eq(1), div:eq(5)')
You could then iterate over the results returned, hope this helps.
然后您可以迭代返回的结果,希望这会有所帮助。
