[英]Selecting parent's next sibling's children in jQuery
This is an illustration of a part of my DOM: 这是我的DOM的一部分的说明:
I want to trigger an effect on div with class des
(which is in an odd div
) on click event of div
with class but
(which is in the previous even div
) 我想触发带班格的效果des
(这是一个奇怪的div
上的点击事件) div
带班but
(这是在以前甚至div
)
How can I select des
from but
? 我如何选择des
but
?
Trivially, if this
is the clicked .but
element: 平凡的,如果this
是点击的.but
元素:
$(this).parent().next().children('.des')
This does assume that there are no other elements in the way, ie that the .even
and .odd
elements are immediate siblings, and that .but
and .des
are immediately children of their respective .even
and .odd
ancestors. 这并假设有在路上没有其他的元素,即在.even
和.odd
元素是直接的兄弟姐妹,和.but
和.des
立即各自的孩子.even
和.odd
祖先。
Less efficiently, but guaranteed to work with any arbitrary number of additional (non-matching) elements in the tree would be: 效率较低,但保证与树中任意数量的其他(非匹配)元素一起使用将是:
$(this).closest('.even').nextAll('.odd').first().find('.des')
It depends on your markup. 这取决于你的标记。 Something like this should work, though: 但是这样的事情应该有效:
$('.but').on('click', function () {
$(this).closest('.even').next().find('.des');
});
