cookie操作

// 获取指定名称的cookie的值
function getCookie(objName) {

	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]);

	}

}
//删除cookie
function delCookie(name)
{

    var exp = new Date(0);
    var cval=getCookie(name);
    if(cval!=null) {
    	document.cookie= name + "="+cval+";expires="+exp.toGMTString();
    }
}
//添加cookie
function addCookie(objName,objValue,objHours){      

    var str = objName + "=" + escape(objValue);

    if(objHours > 0){                               //为时不设定过期时间，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;

}

//两个参数，一个是cookie的名子，一个是值
function SetCookie(name,value)

{

    var Days = 30; //此 cookie 将被保存 30 天

    var exp = new Date();    //new Date("December 31, 9998");

    exp.setTime(exp.getTime() + Days*24*60*60*1000);

    document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();

}
