Changing cookie duration

[juanlu]

Hello!

I've no experience with javascript and i'd like to modify a script, i need to change the cookie duration to 30 days. The cookie portion of the script is the following:

}

function unblockContent(){
    document.getElementsByTagName('body')[0].style.overflow = blocker_originalBodyOverflow;
    document.getElementsByTagName('html')[0].style.overflow = blocker_originalHtmlOverflow;

    document.getElementById('blocker_haze').style.display = 'none';
    document.getElementById('blocker_centerPane').style.display = 'none';
    blocker_setCookie("content_unlocked", 1, 2000);
}

function blocker_setCookie(c_name,value,expiredays){
    var exdate=new Date();exdate.setDate(exdate.getDate()+expiredays);
    document.cookie=c_name+ "=" +escape(value)+((expiredays==null) ? "" : ";expires="+exdate.toGMTString());
}

function blocker_getCookie(c_name){
    if (document.cookie.length>0){
        c_start=document.cookie.indexOf(c_name + "=");
        if (c_start!=-1){ 
            c_start=c_start + c_name.length+1; 
            c_end=document.cookie.indexOf(";",c_start);
            if (c_end==-1) c_end=document.cookie.length;
            return unescape(document.cookie.substring(c_start,c_end));
        } 
    }
    return "";
}

By the way could anyone please tell me what is the current cookie duration on the code above?

Thanks!!

The number of days is set when the function blocker_setCookie is called, which you have not shown us, something like:-

window.onload = blocker_setCookie("MyCookieName", "CookieValue", "365");

so you need to change 365 or whatever to 30.

Thanks for the reply!

I found this part of the code, which i think could be the one to modify. Is the part highlighted the one i need to change? should i change the "1" to another value.
So, right now the cookie is set to 1 day?

function blocker_addLoadEvent(func)
{    
    var oldonload = window.onload;
    if (typeof window.onload != 'function')
    {
        window.onload = func;
    } 
    else 
    {
        window.onload = function()
        {
            oldonload();
            func();
        }
    }
}

blocker_addLoadEvent(blocker_init);

function blocker_init()
{    
   [B] if(blocker_getCookie('content_unlocked')=='[COLOR="Red"]1[/COLOR]')
        return;[/B]

function blocker_setCookie(c_name,value,expiredays){

Thank you very much

Checking the first piece of code i posted there is this part:

blocker_setCookie("content_unlocked", 1, 2000);

What does 1 and 2000 mean in there?

Isn't this part the one i should modify?


I'm including the whole code anyways:

var blocker_originalHtmlOverflow;
var blocker_originalBodyOverflow;

    var oldonload = window.onload;
    if (typeof window.onload != 'function')

        window.onload = func;
    } 
    else 
    {
        window.onload = function()
        {
            oldonload();
            func();
        }
    }
}

blocker_addLoadEvent(blocker_init);

The function blocker_setCookie() is called as follows:-

blocker_setCookie("content_unlocked", 1, 2000);

Where "content_unlocked" is c_name (cookie name)
1 is the cookie value
2000 is expiredays (about 5.5 years)

These parameters are then passed to the function:-

function blocker_setCookie(c_name,value,expiredays){

So if you want the expiry date to be 30 days, alter 2000 to 30.
