		function cookie(name) {

		//得到分割的cookie名值对

		var cookieArray = document.cookie.split("; ");

		var cookie = new Object();

		for (var i = 0; i < cookieArray.length; i++) {

		//将名和值分开

		var arr = cookieArray[i].split("=");

		//如果是指定的cookie，则返回它的值

		if (arr[0] == name) return unescape(arr[1]);

		}

		return "";

		}

		 //删除cookie

		function delCookie(name){

		document.cookie = name + "=;expires=" + (new Date(0)).toGMTString();

		}

		 //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]);

		}

		}

		 //添加cookie

		function addCookie(objName, objValue, objHours) {

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

		//为时不设定过期时间，浏览器关闭时cookie自动消失

		if (objHours > 0) {

		var date = new Date();

		var ms = objHours * 3600 * 1000;

		date.setTime(date.getTime() + ms);

		str += "; expires=" + date.toGMTString();

		}

		document.cookie = str;

		}

		function SetCookie(name, value){

		//此 cookie 将被保存 30 天

		var Days = 30;

		//new Date("December 31, 9998");

		var exp = new Date();

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

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

		}

		 //取cookies函数   

		function getCookie(name){

		var arr = document.cookie.match(new RegExp("(^| )" + name + "=([^;]*)(;|$)"));

		if (arr != null) return unescape(arr[2]);

		return null;

		}

		//删除cookie

		function delCookie(name) {

		var exp = new Date();

		exp.setTime(exp.getTime() - 1);

		var cval = getCookie(name);
