//設置cookie
 function writeCookie (name, value, hours)
    {//name:cookie名字；value：cookie值，hours有效時間（小時）
        var expire = "";
        if (hours != null)
        {
            expire = new Date ((new Date ()).getTime () + hours * 3600000);
            expire = "; expires=" + expire.toGMTString ();
        }
        document.cookie = name + "=" + escape (value) + expire+";path=/";
//      document.cookie="name=value; domain=cookieDomain";//demain是訪問域
    }


    writeCookie ("tyclogoIn","0",0.5);
    console.log(getCookie("tyclogoIn"))


//獲取cookie
function getCookie(name){
            var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)");
                    if(arr=document.cookie.match(reg))
                    return unescape(arr[2]);
                    else
                    return null;
