您的问题来自于您已从文件中读取文本并将其拆分为空格。这样做可以通过字符串中的空格将文本标记为字符串列表。
e.g。 <!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="script.js"></script>
<link rel="stylesheet" type="text/css" href="styles.css">
<script type="text/javascript"></script>

变为"This is a test".split()
因此，您通过["this", "is", "a", "test"]读取的任何输入（完整字符串）都必须以类似的方式进行拆分和比较。
最简单的方法是在空白处不要input，并且您的比较应该按预期工作。
