Javascript操作Cookie
<script>
function getCookieVal(offset) {
var endstr = document.cookie.indexOf(";",offset);
if(endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset,endstr));
}
function FixCookieDate(data) {
var base = new Date(0);
var skew = base.getTime();
if(skew > 0)
date.setTime(date.getTime() - skew);
}
function GetCookie(name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while(i < clen) {
var j = i + alen;
if(document.cookie.substring(i,j) == arg)
return getCookieVal(j);
i = document.cookie.indexOf(" ",i) + 1;
if(i == 0) break;
}
return null;
}
function SetCookie(name,value,expires,path,domain,secure) {
document.cookie = name + "=" + escape(value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
}
function DeleteCookie(name,path,domain) {
if(GetCookie(name)) {
document.cookie = name + "==" +
((path) ? "; path=" + path : "") +
"; expires=The,01-Jan-70 00:00:01 GMT";
}
}
var expdate = new Date();
FixCookieDate(expdate);
expdate.setTime(expdate.getTime() + (365*24*60*60*1000));
</script>
<script>
//读取COOKIE
// alert( readCookie("myCookie") );
function readCookie(name)
{
var cookieValue = "";
var search = name + "=";
if(document.cookie.length > 0)
{

类的定义有3种基本方法:
1、创建并能返回特定类型的对象的函数(工厂函数)如：
function wu()
{
var w=new object;
o.a=1;
return o;
}用这种方式创建对象：var u=wu();
2、创建构造函数，用new实例化例如：
function wu()
{this.a=1;}
用这种方式创建对象: var u=new wu();
3、原型方式,� ......
