实施cookie时出现问题。

我实施cookie来存储游戏数据。这些数据很少，所以cookies应该是正确的想法。我在我的代码中为cookie实现了两个函数。

Im implementing cookies to store data for a game. This data is in small amounts so cookies should be the right idea. Ive implemented two functions in my code for cookies.

function setcookie(cname, cvalue, exdays) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays*24*60*60*1000));
    var expires = "expires="+d.toGMTString();
    document.cookie = cname + "=" + cvalue + "; " + expires;
}
function getcookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for(var i=0; i<ca.length; i++) {
        var c = ca[i].trim();
        if (c.indexOf(name) == 0) return c.substring(name.length,c.length);
    }
    return "";
}

我然后检查是否设置了cookie，根据其他来源这应该有效：

I then put in a check to see if the cookies are set, according to other sources this should work:

if(typeof cookieexists === null){
	starttimer();
}else{
	kernels = getcookie("kernels");
	xtrakernels = getcookie("xtrakernels");
	nbprice = getcookie("nbprice");
	ppprice = getcookie("ppprice");
	kps = getcookie("kps");
	apprice = getcookie("apprice");
	kcprice = getcookie("kcprice");
	starttimer();
}

starttimer（）每秒调用kernps（），这里是kernps（）

starttimer() calls on kernps() every second, here is kernps()

function kernps() {
	kernels = kernels + kps;
	document.getElementById('number').innerHTML = kernels;
	setcookie("kernels", kernels, "100");
	setcookie("xtrakernels", xtrakernels, "100");
	setcookie("nbprice", nbprice, "100");
	setcookie("ppprice", ppprice, "100");
	setcookie("kps", kps, "100");
	setcookie("apprice", apprice, "100");
	setcookie("kcprice", kcprice, "100");
}

以及所有这些，我已经宣布了我的变量（在所有这些之前）

along with all this, i have declared my variables (Before all of this)

var cookieexists = getcookie("kernels");
var kernels = 1;
var xtrakernels = 1;
var nbprice = 50;
var ppprice = 250;
var kps = 0;
var apprice = 75;
var kcprice = 275;

所有变量最终都为null。



我不知道从哪里开始发生了什么。



注意：如果重要的话，我已经尝试并清除了我的cookie。这没用。

What happens is all the variables end up as null.

I have no idea where to start as to what is going on.

NOTE: I have tried and cleared my cookies if that matters. That did not work.
