I have a file input:
我有一个文件输入：
<input type=file id=file onchange='foo(this.files)'/>
Function 'foo' is called only when user chooses some file in the file upload dialog and clicks "OK". Is there any event that will be fired when user clicks "cancel" button in the dialog? HTML5-only solutions are OK.
仅当用户在文件上载对话框中选择某个文件并单击“确定”时，才会调用函数“foo”。当用户点击对话框中的“取消”按钮时，是否会触发任何事件？仅HTML5解决方案是可以的。

This will not do exactly what you want, but you can add files in a queue and then cancel them, and you can capture this event...
这不会完全符合您的要求，但您可以在队列中添加文件然后取消它们，您可以捕获此事件......
