您的功能正在运行，但您没有对该功能做任何事情。你只是得到了 elemant 就是这样。

如果您想在一段时间后打开文件上传，此代码适合您。为了您的理解，我一直保持警惕。

window.onload=formOnWindowLoad();
function formOnWindowLoad(){
 setTimeout(function(){
 document.getElementById('uploadFileOnRemoteServer').click()},500);
}
<br>Select a file to upload: <br />
<form id="fileUploadForm" action="fileLocalUpload.htm?eId=${eId}&tId=${tId}" method="post"enctype="multipart/form-data"> 
<input id="uploadFileOnRemoteServer" type="file" name="uploadingFile" />
<br />
<input type="submit" value="Upload File" />
  
</form>

这对你有用。如果这是你的要求。它将在 3 秒后打开。
