chrome cookie无法设置
Chrome浏览器为了安全只支持online-cookie。也就是,本地不可以设置cookie。这是不是同源策略的设置？

给个例子
<html>
    <head>
        <script language="JavaScript" type="text/javascript">

            function addCookie(objName, objValue, objHours){//添加cookie
                var str = objName + "=" + escape(objValue);
                if (objHours > 0) {//为0时不设定过期时间，浏览器关闭时cookie自动消失
                    var date = new Date();
                    var ms = objHours * 3600 * 1000;
                    date.setTime(date.getTime() + ms);
                    str += "; expires=" + date.toGMTString();
                }
                document.cookie = str;
                alert("添加cookie成功");
            }

            function getCookie(objName){//获取指定名称的cookie的值
                var arrStr = document.cookie.split("; ");
                for (var i = 0; i < arrStr.length; i++) {
                    var temp = arrStr[i].split("=");
                    if (temp[0] == objName)
                        return unescape(temp[1]);
                }
            }

            function delCookie(name){//为了删除指定名称的cookie，可以将其过期时间设定为一个过去的时间
