隐藏特定表的第n个子项 [英] Hiding nth-child of a specific table

问题描述

我在页面上有两个表格.如何处理第二个id="tapp"以运行show/hide nth-child功能?

I have two tables on a page. How do I address the second one, id="tapp", to run show/hide nth-child functions?

我无知地试图通过将id引用添加到'td:nth-child...'

I've ignorantly tried to address the particular table by adding the id reference to the beginning of 'td:nth-child...'

...
var x = document.getElementById("tatt");
$(x.'td:nth-child(3),th:nth-child(3)').hide();
...

推荐答案

在每个逗号分隔的组中，可以在选择器之前加上 id .试试

You can precede the selector by id in each comma separated group. Try

$('#tatt td:nth-child(3), #tatt th:nth-child(3)').hide();

注意:为什么已经使用jQuery的人为什么要使用getElementById()?

Note: Why you are using getElementById() when you already have jQuery?
