Clear just the file input field

I have a file input field with that I want the user to be able to clear just this field and not the whole form.

I have tried with the static event onclick on the remove image link, but it is not working.

<a href="javascript:;" onclick="resetfile();">Remove images</a>

function resetfile() {
      document.getElementById("uploadimages").value = "";
}
