 <h3>请点击屏幕查看效果</h3>
 <script>
  window.onclick = function (e) {
   //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);
  }
 </script>
</body>
