JQuery基于元素的高度添加类

I have a table in an app with data and the thead element in the table has a variable height depending on what user is logged in and using the application. So sometimes the thead element is narrow in height and sometimes it's much taller. Note that there are only two heights that are possible.

我在应用程序中有一个包含数据的表，表中的thead元素有一个可变高度，这取决于用户登录和使用应用程序。所以有时候thead元素的高度很窄，有时更高。注意，只有两个高度是可能的。

I'd like to somehow use jquery to measure the height of the thead element and then add a class so it might come out like this:

我想用jquery来测量thead元素的高度，然后添加一个类，它可能会是这样的:

Narrow:

狭窄:

<thead class="narrow">

Tall:

高:

<thead class="tall">

I am not even sure if this is possible. Thanks.

我甚至不确定这是否可行。谢谢。

It sounds like you're looking for the height function

听起来你在寻找高度函数。

http://api.jquery.com/height/
http://api.jquery.com/height/

With that you can write code like the following

这样，您就可以编写如下代码

var t = $('thead');
t.addClass(t.height() > someValue ? "tall" : "narrow");
