</html>以上是源码， 真不知道该怎么实现cookies保存页面。哪位大侠帮我写一下cookies代码感激不尽！另，<div class="cont" id="aaa">1.1</div>
如果单击其它窗口的标题，1.1窗口title会改变， 但如果去掉 id="aaa" 就不能拖拽了该如何解决呢？
谢谢。
D.getElementById("aaa").innerHTML=element.parentNode.offsetTop+ ","+element.parentNode.offsetHeight;
element.parentNode.offsetTop+ ","+element.parentNode.offsetHeight;
然后再加上层的ID就行了.至于存取COOKIE,有很多代码,随便找两个自定义函数放这.这样足够了,如果你还必须完全现成的代码,那你就不够再做甚至再学这行了吧.
// 保存 Cookie
function setCookie(name, value) {
expires = new Date();
expires.setTime(expires.getTime() + (1000 * 86400 * 365));
document.cookie = name + "=" + escape(value) + "; expires=" + expires.toGMTString() + "; path=/";
}// 获取 Cookie
function getCookie(name) {
cookie_name = name + "=";
cookie_length = document.cookie.length;
cookie_begin = 0;
while (cookie_begin < cookie_length) {
value_begin = cookie_begin + cookie_name.length;
if (document.cookie.substring(cookie_begin, value_begin) == cookie_name) {
var value_end = document.cookie.indexOf(";", value_begin);
if (value_end == -1) {
value_end = cookie_length;
}
return unescape(document.cookie.substring(value_begin, value_end));
}
cookie_begin = document.cookie.indexOf(" ", cookie_begin) + 1;
if (cookie_begin == 0) {
break;
}
}
return null;
}
