js

    绑定父级标签
    let app = document.querySelector("#app");
    监听点击事件
    document.addEventListener("click", function listenClick(e) {
      let x = e.clientX;
      let y = e.clientY;
      创建样式节点
      let circle = document.createElement("span");
      circle.className = "back_span"; // 防止样式冲突，使用指定类名
      circle.style.left = x + "px";
      circle.style.top = y + "px";
      app.appendChild(circle); 
      setInterval(function () {
        circle.remove();
      }, 1000);
    });
