我想設置兩個並排的div由一個較大的div包含到相等的列高度。我嘗試使用下面的jQuery腳本：不明白jQuery的 - 設置相同的高度包含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 = $(this).height();
if(currentHeight > tallestColumn) {
tallestColumn = currentHeight;
}
});
columns.height(tallestColumn);
}
</script>
然後下面是我的DIV的：
<div class="instructionsParent borderDiv borderTable0" style="overflow:hidden">
<div class="instructionsLeft" style="float:left;width:49.5%">
</div>
<div class="instructionsRight" style="float:right;width:49.5%">
</div>
</div>
jQuery的運行，似乎是返回最大高度（451），但沒有按」似乎將它應用於兩個div。我不知道太多的jQuery或JavaScript，不明白以下內容：「setEqualHeight（$（」。instructionsParent> div「））;」
難道是我的編碼不正確嗎？
謝謝 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>

我得到了預期的對象JScript的錯誤，如果我刪除頁面加載。查詢確實運行並返回一個很好的值，但不會將其應用於div。 – James 2009-09-22 05:32:30
我的網頁適合你嗎？你能告訴我你的頁面嗎？ – 2009-09-22 05:36:38
哦，我明白了。是的，你的例子工作正常。先讓我檢查幾件事情。 謝謝，吉姆 – James 2009-09-22 05:41:29
