有相对的jQuery选择器之类的东西吗? [英] Is there such thing as a relative jQuery selector?
问题描述
我使用this
变量引用了一个jquery对象.我正在寻找一种将子选择器应用于对象的方法.
I have a reference to a jquery object with the this
variable. I am looking for a way of applying the child selector to the object.
我正在使用$(this).find('table > tbody > tr > td')
,但我的目标是更像$('[Value of $(this) goes here somehow] > table > tbody > tr > td')
.
I'm using $(this).find('table > tbody > tr > td')
, but what I'm aiming for is something more like $('[Value of $(this) goes here somehow] > table > tbody > tr > td')
.
我意识到我可以做到$(this).children('table').children('tbody').children('tr').children('td')
,但是我想知道这里是否可以使用一些语法糖.
I realise that I can do $(this).children('table').children('tbody').children('tr').children('td')
, but I was wondering if there was some syntactic sugar I could use here.
推荐答案
您可以从子选择器开始(>
),同时使用 .find()
时,就像这样:>
$(this).find('> table > tbody > tr > td')
这是一个经常被忽视的用例,但是对于您所追求的东西来说却非常有用.
It's an often overlooked use case, but it works just great for what you're after.
