函数不会读取全局变量的值 - JavaScript

Question

我在这里遇到麻烦。我有一个应该有两个状态的变量。我想检查状态是否已经改变，即使它已经改变了，我的功能还是继续说它没有。看看：

<script type="text/javascript">
var i = 0;
//More unrelated code here
function Talk(url) {
	just_done = 0;
	//alert("Hey!");
	buttons = document.getElementsByTagName("input");
	iframe = document.getElementsByTagName("iframe");
	//alert("Hey!");
	if (url == "scheduler.html" && talk == 0 && just_done == 0) {
		trc = parseInt(getCookie("trc"));
		if (getCookie("trc") == "NaN") {
			trc = 0;
		}
		if ((getCookie("trc")) == undefined) {
			trc = 0;
		}
		//alert("It started.");
		stop = 0;
		buttons[0].value="          Stop Listening          ";
		iframe[0].src=url;
		//alert("It should be removed");
		talk = 1;
		just_done = 1;
	}
	if (url == "scheduler.html" && talk == 1 && just_done == 0) {
		//alert("It stopped.");
		stop = 1;
		full_time = getTimeSince() + klove;
		document.cookie="klove=" + full_time;
		buttons[0].value="          Listen Now          ";
		iframe[0].src="";
		// //alert("It should be removed");
		talk = 0;
		just_done = 1;
		//alert(full_time);
	}
	if (url == "http://emf.mp3.miisolutions.net:80/kl/klove_itunes" && music == 0 && just_done == 0) {
		klove = parseInt(getCookie("klove"));
		if ((getCookie("klove")) == "NaN") {
			klove = 0;
			//alert("K-Love seemed to be null.");
		}
		if ((getCookie("klove")) == undefined) {
			klove = 0;
		}
		//alert("It started.");
		stop = 0;
		iframe[0].src=url;
		// //alert("It should be removed");
		music = 1;
		just_done = 1;
	}
	if (url == "http://emf.mp3.miisolutions.net:80/kl/klove_itunes" && music == 1 && just_done == 0) {
		//alert("It stopped.");
		stop = 1;
		full_time = getTimeSince() + klove;
		document.cookie="klove=" + full_time;
		iframe[0].src="";
		// //alert("It should be removed");
		music = 0;
		just_done = 1;
		//alert(full_time);
	}
	if (url == "http://tunein.streamguys1.com/cnn" && news == 0 && just_done == 0) {
		cnn = parseInt(getCookie("cnn"));
		if ((getCookie("cnn")) == "NaN") {
			cnn = 0;
			//alert("CNN seemed to be null.");
		}
		if ((getCookie("cnn")) == undefined) {
			cnn = 0;
		}
		//alert("It started.");
		stop = 0;
		iframe[0].src=url;
		// //alert("It should be removed");
		news = 1;
		just_done = 1;
	}
	if (url == "http://tunein.streamguys1.com/cnn" && news == 1 && just_done == 0) {
		//alert("It stopped.");
		stop = 1;
		full_time = getTimeSince() + cnn;
		document.cookie="cnn=" + full_time;
		iframe[0].src="";
		// //alert("It should be removed");
		news = 0;
		just_done = 1;
		//alert(full_time);
	}
}
stop = 0;
Time();
function Time() {
	if (stop == 0) {
	i = i + 1;
	alert(i);
	setTimeout(Time, 1000);
	}
	if (stop != 0) {
	alert("I'm done. It's " + i);
	}
}
</script>
<input width="10px" height="6px" id="button" type="button" onClick='Talk("scheduler.html")' value="          Listen Now          "></input>

奇怪我有这个问题，当他们遇到类似的问题时，我已经在这个网站上关注了每个人的说明，但这仍然无效。

编辑：让我补充一点，将stop设置为1的if语句在另一个函数中。

编辑2：这是更多代码，因此您可以触发我的问题。
