JavaScriptでcookieの書き出しを行う

JavaScriptでcookieの書き出しを行う関数

function setCookie(key, val, tmp) {
	tmp = key + "=" + escape(val) + "; ";
	tmp += "expires=Tue, 31-Dec-2030 23:59:59; ";
		document.cookie = tmp;
		console.log(document.cookie)
}
function getCookie(key,  tmp1, tmp2, xx1, xx2, xx3) {
	tmp1 = " " + document.cookie + ";";
	xx1 = xx2 = 0;
	len = tmp1.length;
	while (xx1 < len) {
		xx2 = tmp1.indexOf(";", xx1);
		tmp2 = tmp1.substring(xx1 + 1, xx2);
		xx3 = tmp2.indexOf("=");
		if (tmp2.substring(0, xx3) == key) {
		    return(unescape(tmp2.substring(xx3 + 1, xx2 - xx1 - 1)));
		}
		xx1 = xx2 + 1;
	}
	return("");
}
