JS实现页面鼠标点击出现图片特效

let div = document.createElement("div");
 div.id = "mouseImg";
 for (let i =0 ; i <3 ;i++){
 let img = document.createElement("img");
 img.src = "images/timg.gif";
 div.appendChild(img);
 }
 document.body.appendChild(div);
 let divImg = document.querySelector("#mouseImg");
 document.addEventListener("mousedown",function (e) {
 let x = e.pageX;
 let y = e.pageY;
 divImg.style.left = x + "px" ;
 divImg.style. = y + "px";
 let imgs = divImg.children;
 for (let i =0 ; i < imgs.length ;i++) {
 imgs[i].style.opacity = "1";
 setTimeout(function () {
 imgs[i].style.opacity = "0";
 },2200);
 }
 });

body {
 background-color: rgba(0, 255, 255, 0.12);
 cursor: pointer;
 }
