我想设置两个并排的div由一个较大的div包含到相等的列高度。我尝试使用下面的jQuery脚本：不明白jQuery的 - 设置相同的高度包含div
<script type="text/javascript" language="javascript">
function pageLoad() {
$(document).ready(function() {
setEqualHeight($(".instructionsParent > div"));
});
}
function setEqualHeight(columns) {
var tallestColumn = 0;
columns.each(function() {
currentHeight = $(this).height();
if(currentHeight > tallestColumn) {
tallestColumn = currentHeight;
}
});
columns.height(tallestColumn);
}
</script>
然后下面是我的DIV的：
<div class="instructionsParent borderDiv borderTable0" style="overflow:hidden">
<div class="instructionsLeft" style="float:left;width:49.5%">
</div>
<div class="instructionsRight" style="float:right;width:49.5%">
</div>
</div>
jQuery的运行，似乎是返回最大高度（451），但没有按”似乎将它应用于两个div。我不知道太多的jQuery或JavaScript，不明白以下内容：“setEqualHeight（$（”。instructionsParent> div“））;”
难道是我的编码不正确吗？
谢谢 詹姆斯

This tiny control-program is only installed ONCE on a given machine,
and is there to assist with all future downloads.
It allows you to download a batch of several files at once, save
them wherever you wish, AND keeps track of the download progress. If your internet connection glitches, the
download will *automatically restart* (after a couple of minutes)
from where it left off, once the internet connection is restored, presuming that your computer remains powered on.
This is a very important feature, since these are BIG files that may take
several hours to download if you have a relatively slow internet connection.</strong>

If the transfer fails because your computer shut down from a power-outage, there may be a temporary file left on your
machine - but the next time you start the download, it automatically cleans up what was left from the aborted transfer.
If you tend to get hit by electric power outages more often than normal, we recommend that you purchase a battery-backup UPS
(Uninterruptible Power Supply) that has at least 1500VA capacity so that the computer AND your modem AND router can remain
powered-up for several hours when the power goes out. Start the download before going to bed, and TURN OFF the monitor
during that process, so that the UPS would not have to feed it if a power outage hits.</strong>

If you are in the midst of a long download session, but for some reason you must interrupt it and turn off your computer
a while, then if you want to resume the download from where you left off, be sure to HIBERNATE your machine rather than
doing a simple shutdown. You can set this up from Control Panel > Power Options > Hibernate Tab. There will be a button
on your keyboard somewhere that activates hibernation (sometimes called "sleep"). It takes a complete "RAM snapshot" of
what is going on, so that the next time you start the computer, it resumes exactly where it left off (it may take a few
minutes after restart for the download to auto-resume).</strong>

我得到了预期的对象JScript的错误，如果我删除页面加载。查询确实运行并返回一个很好的值，但不会将其应用于div。 – James 2009-09-22 05:32:30
我的网页适合你吗？你能告诉我你的页面吗？ – 2009-09-22 05:36:38
哦，我明白了。是的，你的例子工作正常。先让我检查几件事情。 谢谢，吉姆 – James 2009-09-22 05:41:29
