cookie很實用的一個功能,可以判斷某個狀態,在項目中使用率極高
function setCookie(name,value)
{
var Days = 30;
var exp = new Date();
exp.setTime(exp.getTime() Days*24*60*60*1000);
document.cookie = name "=" escape (value) ";expires=" exp.toGMTString();
var strsec = getsec(time);
var exp = new Date();
exp.setTime(exp.getTime() strsec*1);
document.cookie = name "=" escape (value) ";expires=" exp.toGMTString();
}
//讀取cookies
function getCookie(name)
{
var arr,reg=new RegExp("(^| )" name "=([^;]*)(;|$)");
if(arr=document.cookie.match(reg))
return (unescape(arr[2]));
else
return null;
}
//刪除cookies
function delCookie(name)
{
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null)
document.cookie= name "=" cval ";expires=" exp.toGMTString();
}
