jQuery初学者::仅适用于直接后代 [英] JQuery beginner: :has for direct descendants only

问题描述

假设树形结构如下: (糟糕的旧版布局，很抱歉)

Assuming a tree structure like the following: (Ugly legacy layout, sorry)

<tr>                          (1) dont want to select this one  
   <td>
       <table>
           <tr>               (2) not a "special" td, dont select       
               <td.normal>        
           <tr>                (3) this is what I want to select
               <td.special>       
           <tr>
               <td.normal>

我想选择具有特殊类的td的tr作为直接后代， 即，只有(2)，不是(3)[其td不特殊]，也不是(1)[特殊的td不是直接后代，而是孙子"]

I want to select the tr which has a td with class special as direct descendant, i.e. only (2), not (3) [its td is not special], and also not (1) [special td is not a direct descendant but a "grandkid"]

我尝试了

$("tr:has(td.special)");

但是这给了我(1)和(2)，因为:has的意思是在我所有后代之中".

but that gives me (1) and (2), because :has means "has somewhere among all my descendants".

我需要的是:has，但意思是在我的直系子女中".

What I need is something like :has, but meaning "has among my direct children".

或者，一种向上横向的方式，例如仅选择当前选定元素的父级".

Alternatively, a way to transverse upwards, like "select only the parent of the currently selected element".

很抱歉，这个问题很简单，但是我似乎无法在API文档的任何地方找到它.

Sorry for the simple question, but I can't seem to find it anywhere in the API docs.

推荐答案

您尝试过$("td.ptextno:contains('Betreuung')").parent()吗?

看起来问题的示例已更改...尝试$("td.special").parent()
众所周知，遍历文档位于此处: http://docs.jquery.com/Traversing

Looks like the question's example changed... try $("td.special").parent()
EDIT 2: Just so you know, the docs on traversing are here: http://docs.jquery.com/Traversing
