设置两个元素的高度以使其彼此匹配 [英] Setting the height of two elements to match each other
问题描述
大家好，
我想编写一个函数，给出两个元素将使他们的
高度等于更大的元素。我已经去了它并且它有效，
但它使它们的高度都比它们中的任何一个都大（但是相等）
代码如下：
var newheight =（second.offsetHeight> first.offsetHeight）？
second.offsetHeight：
first.offsetHeight;
first.style.height = newheight +" px";
second.style.height = newheight +" px" ;;
所以，我显然做了一些愚蠢的事情，但是有人可以启发我吗？
我试着写一下offsetHeight但是这些改变似乎被忽略了。
干杯，
Andy
Hi all,
I want to write a function that given two elements will make their
heights equal to the larger element. I''ve had a go at it and it works,
but it makes both their heights larger than either of them (but equal)
The code is as follows:
var newheight = (second.offsetHeight > first.offsetHeight) ?
second.offsetHeight :
first.offsetHeight;
first.style.height = newheight + "px";
second.style.height = newheight + "px";
So, I''m obviously doing something stupid, but can anyone enlighten me?
I tried writing to offsetHeight but the changes seemed to be ignored.
Cheers,
Andy

first.style.height = newheight +" px";
second.style.height = newheight +" px";

好的，我明白了：
123
153
153
如果我在之后发出相同的警报：
first.style.height = newheight +" px";
second.style.height = newheight +" px";
我得到：
162
162
153
所以，那是我的问题。它们现在的高度相同但是我的查询
表示它们都比以前更大。
干杯，

OK, I get:
123
153
153
If I put the same alerts in after:
first.style.height = newheight + "px";
second.style.height = newheight + "px";
I get:
162
162
153
So, that''s my problem. They are now equal in height but as my query
said it makes both of them larger than either was before.

问这个在一个CSS论坛中，我相信他们会有办法做到这一点（或者至少让它看起来像是在发生这种情况），而不需要任何脚本。
尝试：
comp.infosystems。 www.authoring.stylesheets

Asking this in a CSS forum, I''m sure they''ll have a way to do this (or
at least make it look like it''s happening) without any scripting.
Try:
comp.infosystems.www.authoring.stylesheets
