我试图创建一个登录页面，当单击登录按钮时，它会从固定的 Excel 文件中检查用户名和密码，但该按钮没有任何响应。
我尝试了所有方法，这就是我的完整想法：修复了包含多个用户的 Excel 工作表文件（密码、用户名、年龄、性别、地址和电话号码），因此当单击登录时，应该使用输入的密码和用户名输入，搜索用户，如果找到，则检查密码。
我不知道为什么即使我使用 onclick 或 Submit，我的按钮也没有响应。它甚至不发出警报。
document.getElementById('loginButton').addEventListener('click', function() {
console.log('button clicked');
var username = document.getElementById('username').value;
var password = document.getElementById('password').value;
var fileName = 'data.xlsx'; // Fixed file name
/*
fetch(fileName)
.then(response => response.arrayBuffer())
.then(data => {
var workbook = XLSX.read(data, {
type: 'array'
});
var firstSheet = workbook.Sheets[workbook.SheetNames[0]];
var cellUsername = firstSheet['A1'] ? firstSheet['A1'].v : '';
var cellPassword = firstSheet['B1'] ? firstSheet['B1'].v : '';
if (username === cellUsername && password === cellPassword) {
window.location.href = 'profile.html';
} else {
alert('Invalid username or password');
}
})
.catch(error => console.error('Error fetching data:', error));
