这是我的 html 脚本，它使用 JavaScript 和日程表格式来设置一天中某个时间段的计时器，有人可以帮助我将日程表链接到 Json 文件，以便更轻松地进行交换。
我该如何编写这段代码，以便当它需要时间表时，它会引用一个名为“Schedule.txt”的 txt 文件：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Class Timer</title>
<style>
body {
font-family: Arial, sans-serif;
text-align: center;
}
</style>
</head>
<body>
<h1>Class Timer</h1>
<p id="class-info"></p>
<p id="countdown"></p>
<script>
// Schedule data, can be easily updated!

我尝试使用 Chat-gpt 来帮助解决问题，但每次我尝试它所说的内容时，它都会破坏代码。
