JavaScript代码:

// 下拉菜单

dropdown[i].addEventListener("click", function() {
this.classList.toggle("active");

dropdownContent.style.display = "none";
} else {
dropdownContent.style.display = "block";
}
});
}
// 图片轮播
var slideIndex = 0;
showSlides();
function showSlides() {
var i;
var slides = document.getElementsByClassName("mySlides");
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
slideIndex++;
if (slideIndex > slides.length) {slideIndex = 1}
slides[slideIndex-1].style.display = "block";
setTimeout(showSlides, 2000); // 切换时间为 2 秒
}
// 渐变背景
var gradient = document.getElementById("gradient");
var colors = ["#333", "#666", "#999", "#ccc", "#fff"];
var index = 0;
function changeGradient() {
gradient.style.background = "linear-gradient(to bottom, " + colors[index] + ", " + colors[index+1] + ")";
index++;
if (index == colors.length - 1) {
index = 0;
}
}
setInterval(changeGradient, 5000); // 切换时间为 5 秒
// 动态时钟
function showTime() {
var date = new Date();
var hours = date.getHours();
var minutes = date.getMinutes();
var seconds = date.getSeconds();
var ampm = hours >= 12 ? "PM" : "AM";
hours = hours % 12;
hours = hours ? hours : 12;

var time = hours + ":" + minutes + ":" + seconds + " " + ampm;
document.getElementById("clock").innerHTML = time;
}
setInterval(showTime, 1000); // 刷新时间为 1 秒
// 密码验证
var password = document.getElementById("password");
var confirmPassword = document.getElementById("confirm-password");
var message = document.getElementById("message");
