How to detect input type=file "change" for the same file?

You can simply set to null the file path every time user clicks on the control. Now, even if the user selects the same file, the onchange event will be triggered.

<input id="file" onchange="file_changed(this)" onclick="this.value=null;" type="file" accept="*/*" />

If you have tried .attr("value", "") and didn't work, don't panic (like I did)

just do .val("") instead, and will work fine

You can trick it. Remove the file element and add it in the same place on change event. It will erase the file path making it changeable every time.

Or you can simply use .prop("value", ""), see this example on jsFiddle.
