getting or setting cookies with javascript

Question

My question is if I can set a cookie using javascript (and read it)

My first impression is that the code beneath doesn't work If I look in my vista cookie folder, I can not see the name of the cookie

function zetCookie(naam,waarde,dagen) {     // setCookie(name,value,days)
    if (dagen) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var verloopdatum = "; expires="+date.toGMTString(); // expiry_date
    }
    else var verloopdatum = "";
    document.cookie = naam+"="+waarde+verloopdatum+"; path=/";
}    

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

I'm testing it here: http://flamencopeko.net/cookie.php and here: http://flamencopeko.net/cookie.js. Works perfect.

And, yeah, Firebug's Cookies panel is great.

I'm trying to use your script to save font size preference. Here is a thread on that: simplify font size toggle.

I can't answer why the cookie is not showing in your Vista folder, but that code properly sets and reads cookies as intended. How are you testing it? An easier way to test whether the cookies are sticking is by simply doing something like this:

<input type="button" value="Set" onClick="createCookie('test','yay',5);">
<input type="button" value="Read" onClick="alert(readCookie('test'));">

You can refresh the page between Setting and Reading it if makes you feel better, but it works for me.

If that doesn't show what you're expecting, make sure your browser is setup to accept cookies. :)

EDIT: Looking at your code, you missed replacing days in this line:

date.setTime(date.getTime()+(days*24*60*60*1000));

How are you setting the cookies? I added a link to a sandbox where I tested the code and it works fine. – Paolo Bergantino May 13 '09 at 23:49
also, does the readcookie() ignore the user@ that goes before the cookiename? – May 13 '09 at 23:51
Maybe. I'm not really familiar with how browsers store the cookies or whatever, so I can't really comment on the user@ part. – Paolo Bergantino May 14 '09 at 00:07
it is definitivly something in the syntax, because it stops execution off the code from the point it runs into the function that supposed too set the cookie – May 14 '09 at 00:12
Can you edit your question to show the code you are using to test the functions? – Paolo Bergantino May 14 '09 at 00:14
I know it, I diddn't change all off the variable names in my translation (see days), sorry, better post the code that I actually use. – May 14 '09 at 00:57
