Jquery - How to find an element using class and attribute
提问by Murtaza Mandvi
I am trying to figure out the most efficient way to find my element. Following i smy structure:
我试图找出最有效的方法来找到我的元素。遵循我的结构：
<div class="a" customattrib="2">
in order to find this element can I do something like :
为了找到这个元素，我可以做类似的事情：
$("div.a [customattrib='2']")
This does not seem to work, is there another way to do this?
这似乎不起作用，有没有其他方法可以做到这一点？
Without the class I am able to get the value but I do not think this is efficient enough for my structure:
没有课程，我可以获得价值，但我认为这对我的结构来说不够有效：
$("div [customattrib='2']")
回答by SLaks
Remove the space:
删除空格：
$("div.a[customattrib='2']")
By putting in the space, you're making it into a descendant selector which finds all elements that match [customattrib='2']and are insidean element that matches div.a.
通过放入空格，您将其变成了一个后代选择器，它会查找所有匹配的元素[customattrib='2']并位于匹配的元素内div.a。
