Javascript 测量多个 Div 高度
我正在尝试使用 jQuery 构建一个手风琴菜单，但遇到了跳跃的动画。跳动是因为没有设置div的高度造成的。我的问题是每个 div 都会根据内容有不同的高度；所以问题是，我如何使用 javascript 来查看带有“子菜单”类的每个 div，测量它的高度并设置它。
这是我到目前为止所得到的：
$('.submenu').each(function() {
var divh = $(this).height();
$(this).css('height', divh + 'px');
});
我遇到的是，它似乎只测量一个 .submenu div 并将它们全部设置为该高度。想法？提前致谢！
I'm trying to build out an accordion menu with jQuery but am running into jumpy animations. The jumpiness is caused by not setting a height for the div. My problem is that each div is going to have a different height based on the contents; so the question is, how would I use javascript to look at each div with the class 'submenu', measure it's height, and set it.
Here is what I have so far:
$('.submenu').each(function() {
var divh = $(this).height();
$(this).css('height', divh + 'px');
});
What I'm running into is that it only seems to measure one .submenu div and sets all of them to that height. Thoughts? Thanks in advance!

相信我发现了问题。我将上面的脚本放在 $(document).ready() 函数中，该函数只会加载并随后测量 DOM。将其移动到 $(window).load() 函数，让它查看内容，然后测量高度。作为澄清点，.submenu 类 div 是折叠式 div。
Believe I found the problem. I had the above script in a $(document).ready() function which would only have loaded, and subsequently measured, the DOM. Moved it to a $(window).load() function which let it see the content and then measure the height. As a point of clarification the .submenu class divs are the accordion divs.
假设也像这样：
您需要始终将当前 div 高度添加到您的手风琴 div 中
Suppose too look like this :
You need to always add the current div height in your for to your accordion div
