JavaScript读写Cookie

//读取cookie的函数 
function readcookie(name) { 
	var cookievalue = ""; 
	var search = name + "="; 
	if(documents.cookie.length > 0) { 
		offset = documents.cookie.indexof(search); 
		if (offset != -1) { 
			offset += search.length; 
			end = documents.cookie.indexof(";", offset); 
			if (end == -1) end = documents.cookie.length; 
			cookievalue = unescape(documents.cookie.substring(offset, end)) 
		} 
	} 
	return cookievalue; 
} 

//写入cookie的函数 
function writecookie(name, value, hours){ 
	var expire = ""; 
	if(hours != null) { 
	expire = new date((new date()).gettime() + hours * 3600000); 
	expire = "; expires=" + expire.togmtstring(); 
	} 
	documents.cookie = name + "=" + escape(value) + expire; 
}
