<h3>请点击屏幕查看效果</h3>
<script>

//存储需要的颜色
let arr = ["red", "yellow", "green", "pink", "blue", "purple", "orangered"];
//随机产生一个颜色
let heartNum = Math.floor(Math.random() * arr.length);
let div = document.createElement("div");
div.setAttribute("class", "iconfont iconzan div-box");
div.style.color = arr[heartNum];
document.body.appendChild(div);
//获得鼠标的x,y轴的位置，并减去自身宽高的一半，使其能够在爱心的正中心
let x = e.pageX - div.offsetWidth / 2;
let y = e.pageY - div.offsetHeight / 2;
div.style.left = x + "px";
div.style.top = y + "px";
//获得0-1的整数
let num = Math.round(Math.random());
let timer = setInterval(() => {
y -= 10;
if (num === 0) x -= 10;
else x += 10;
div.style.left = x + "px";
div.style.top = y + "px";
//如果超出屏幕范围，则删除此节点
if (y < -100) {
clearInterval(timer);
div.remove();
}
}, 100);
}
