浏览器保存cookies的问题

[chenshizhencong]

这是我读写删cookies的代码:

function setCookies(cname, cvalue, expiredays) {
    var exdate = new Date();
    exdate.setTime(exdate.getTime() + expiredays * 3600 * 1000);
    var cookieValue = cname + "=" + escape(cvalue) + ((expiredays == null) ? "" : ";expires=" + exdate.toGMTString()+";path=/");  
    document.cookie = cookieValue;
}
function getCookie(cname) {
    if (document.cookie.length > 0) {
        var cstart = document.cookie.indexOf(cname + "=");
        if (cstart >= 0) {
            cstart = cstart + cname.length + 1;
            cend = document.cookie.indexOf(";", cstart);
            if (cend == -1) {
                cend = document.cookie.length;
            }
            return unescape(document.cookie.substring(cstart, cend));
        }
    }
    return "";
}
function delCookie(cname) {
    alert(getCookie(cname))
    if (getCookie(cname).length > 0) {       
        document.cookie = cname + "=" + ";expire=" + (new Date()).toGMTString();
    }
}

在IE和火狐下是正常，可以写入保存都是OK的，但是google浏览器下保存不了，从网上找了下说是在网络中是可以的，但是发布之后再用google浏览器查看，还是不行，有哪位高手知道要怎么在google浏览器下写入cookies的吗？，还是我的代码有问题呢?
