关于游览器 cookie的操作类

var Cookie = {

	getCookie : function(c_name,is){

		var value = this._getCookie(c_name);

		if(JSON && is != false){

			try
			{
				value = JSON.parse(value);
			}
			catch (e)
			{ 

			} 

		}

		return value;

	},

	_getCookie : function(c_name){
		if (document.cookie.length>0)
			{
				c_start=document.cookie.indexOf(c_name + "=")
			if (c_start!=-1)
			{
				c_start=c_start + c_name.length+1
				c_end=document.cookie.indexOf(";",c_start)
				if (c_end==-1) c_end=document.cookie.length
					return unescape(document.cookie.substring(c_start,c_end))
				}
			}
		return "";
	},

	setCookie : function(c_name,value,expiredays){

		if(typeof value == "object" ) {

			if(window.JSON){

				value = JSON.stringify(value);

			}

		}

		return this._setCookie.apply(this,arguments);

	},

	_setCookie : function (c_name,value,expiredays){
		var exdate=new Date()
		exdate.setDate(exdate.getDate()+expiredays)
		document.cookie=c_name+ "=" +escape(value)+
		((expiredays==null) ? "" : ";expires="+exdate.toGMTString())
	},

	getCookieToJson : function(){

	},

	remove : function(name){

		var str = document.cookie;

	}

}

很容易简介的

我就不多介绍了
