IE 11使用HTML input = file标记时锁定文件 [英] IE 11 lock the file when using HTML input=file tag

问题描述

1. 我在IE11中输入的文件中通过浏览选择文件

1. I choose the file using browse in the file input in IE11

我在资源管理器中使用shift + delete删除了文件

I deleted the file using shift+delete in the Explorer

然后，当我刷新文件夹时，删除的文件会再次出现在资源管理器中.

Then when I refresh the folder, the file that I deleted reappear again in Explorer.

无论如何，我可以通过客户端javascript释放文件句柄吗?我在IE 8中尝试了该测试，但未出现该问题.

Is there anyway that I can release the file handle by at the client side javascript? I tried that test in IE 8 but that issue didn't occurred.

感谢任何帮助.

    document.getElementById("fileToUpload").value=""; // input file field
    document.getElementById("uploadForm").reset(); // form that containing input file field
