我有一个页面，最初显示页面上第一个div的内容， 基于内部样式表。根据菜单选择它成功 显示所选的div并使用名为foo的函数隐藏其他div。 每个div都有指向外部页面的链接。我遇到的问题是，当 用户选择一个链接，然后点击我的页面显示第一个的后退箭头 在页面上显示div并显示菜单上的上一个选项。我想要 显示菜单中显示的div。我希望这是有道理的。 附件是我的代码和页面使用的外部样式表。

1) Padding is only placed on the top and/or bottom of the divs. The elements within these divs have padding on their sides. This saves you from any "box model math". Keep in mind, if you add any side padding or border to the div itself, it will be added to the width you define to create the *total* width. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design.
2) No margin has been given to the columns since they are all floated. If you must add margin, avoid placing it on the side you're floating toward (for example: a right margin on a div set to float right). Many times, padding can be used instead. For divs where this rule must be broken, you should add a "display:inline" declaration to the div's rule to tame a bug where some versions of Internet Explorer double the margin.
3) Since classes can be used multiple times in a document (and an element can also have multiple classes applied), the columns have been assigned class names instead of IDs. For example, two sidebar divs could be stacked if necessary. These can very easily be changed to IDs if that's your preference, as long as you'll only be using them once per document.
4) If you prefer your nav on the right instead of the left, simply float these columns the opposite direction (all right instead of all left) and they'll render in reverse order. There's no need to move the divs around in the HTML source.

要做到这一点，您需要记住用户选择的内容。一种方法是使用cookie。
这是我用来处理cookie的几个javascript函数。
function createCookie(name, value, days) {
var expires;
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toGMTString();
} else {
expires = "";
}
document.cookie = escape(name) + "=" + escape(value) + expires + "; path=/";
}
function readCookie(name) {
var nameEQ = escape(name) + "=";
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = cookies[i];
while (cookie.charAt(0) === ' ')
cookie = cookie.substring(1, cookie.length);
if (cookie.indexOf(nameEQ) === 0)
return unescape(cookie.substring(nameEQ.length, cookie.length));
}
return null;
}
在你的foo（）函数中调用createCookie（）来保存所选的选项。然后添加一个函数句柄页面加载事件。在那里，调用readCookie（）来获取所选的选项以确定要显示的div。
