Js cookie操作

如代码：

<script type="text/javascript">
document.cookie="name=zhangsan; ";
document.cookie="age=16; ";

function setCookie(key,value,t) {//t为秒
        var exp = new Date();
        exp.setTime(exp.getTime() + t*1000);
        document.cookie = key + '=' + value + ';expires=' + exp.toGMTString()+";path=/;domain=.9888.cn";
    }

function getCookie(key) {//获取指定名称的cookie的值 
    var arr1 = document.cookie.split('; ');
    for (var i=0; i<arr1.length; i++) {
        var arr2 = arr1[i].split('=');
        if (arr2[0] == key) {
            return arr2[1];
        }
    }
}

//删除cookies 
function delCookie(name) 
{ 
    var exp = new Date(); 
    exp.setTime(exp.getTime() - 1); 
    var cval=getCookie(name); 
    if(cval!=null) 
        document.cookie= name + "="+cval+";expires="+exp.toGMTString(); 
}

</script>
