	function Trim(strValue) {
	 return strValue.replace(/^\s+|\s+$/g, '');
	}

	function getCookie(key) {
	 var result = false;
	 if(document.cookie) {
	 var mycookieArray = document.cookie.split(';');
	 for(i=0; i<mycookieArray.length; i++) {
	 var mykeyValue = mycookieArray[i].split('=');
	 if(Trim(mykeyValue[0]) == key) result = mykeyValue[1];
	 }
	 }
	 return result;
	}

	function setCookie(key, value, hoursExpire) {
	 var ablauf = new Date();
	 var expireTime = ablauf.getTime() + (hoursExpire * 60 * 60 * 1000);
	 ablauf.setTime(expireTime);
	 document.cookie = key + "=" + value + "; expires=" + ablauf.toGMTString();
	}

	var mycookie = getCookie('meincookie');
	if(!mycookie) {
	 // do whatever you want if the cookie is not set
	 setCookie('meincookie', 'true', 24);
	} else {
	 // do whatever you want if the cookie is set
	 // mycookie contains the cookie value
	}
