getting or setting cookies with javascript

Question

Hello,

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 the name off the cookie

    function zetCookie(naam,waarde,dagen) {
    if (dagen) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var verloopdatum = "; expires="+date.toGMTString();
    }
    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;
}

thanks,Richard

Answer 1

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));
