window.addEventListener("upload", ()=>{
const input = document.getElementById("upload");
const filewrapper = document.getElementById("filewrapper");
input.addEventListener("change",(e)=>{
let fileName = e.target.files[0].name;
let filetype = e.target.value.split(".").pop();
fileshow(fileName, filetype);
})
const fileshow=(fileName, filetype)=>{
const showfileboxElem = document.createElement("div");
showfileboxElem.classList.add("showfilebox");
const leftElem = document.createElement("div");
leftElem.classList.add("left");
const fileTypeElem = document.createElement("span");
fileTypeElem.classList.add("filetype")
fileTypeElem.innerHTML=filetype;
leftElem.append(fileTypeElem);
const filetitleElem = document.createElement("h3");
filetitleElem.innerHTML=fileName;
leftElem.append(filetitleElem);
showfileboxElem.append(leftElem);
const rightElem = document.createElement("div");

问题是标签（您看到的上传图标）被设置为for=“upload”。这意味着它链接到id=“upload”的输入。
但是，输入有一个name=“upload”，但没有ID。
如果您将其添加到输入的属性中，则会出现文件选择弹出窗口。
