HTML5 input type file Error handling

I build a module to upload files using HTML5 input type file element. I found I issue which I need to address/ resolve by showing proper error message:-

1) User selects a file to upload but before pressing uploading button user deleted the source file. now user clicks upload button. In my case nothing happens on UI.

I want to ask that by any means we can know weather file still exists before clicking upload button on input type file element of HTML5.

Pls Note: I am using ember.js
