How to clear a previous file from a 'input type' in HTML5 FileReader

Question

I have a file-input:

<img id="uploadPreview">
   <div id="changeImage">Change</div>
<div id="customImage">
   <input type="file" id="myfile" multiple style="display:none" onchange="PreviewImage();" />
   <div class='upload blank' id="add-image"></div>
</div>

The function is like below:

var oFReader = new FileReader();
oFReader.readAsDataURL(document.getElementById("myfile").files[0]);

oFReader.onload = function (oFREvent) {
    document.getElementById("uploadPreview").src = oFREvent.target.result;
};

function PreviewImage() {
        var oFReader = new FileReader();
        oFReader.readAsDataURL(document.getElementById("myfile").files[0]);
        $("#uploadPreview").removeClass('hide'); //for manipulating something in the dom
        $('#changeImage').removeClass('hide'); //for manipulating something in the dom
        $("#customImage").addClass('hide'); //these are for manipulating something in the dom

        oFReader.onload = function (oFREvent) {
            document.getElementById("uploadPreview").src = oFREvent.target.result;
        };
    };

Everything works perfect. Now I have a Change button. I want if someone clicks on it then previous uploaded file-details to be gone. The function is something like below:

$('#changeImage').click(function(){
  $('#uploadPreview').addClass('hide');
  $('#customImage').removeClass('hide');
  //here I want to remove/clear the details about the already previous uploaded file in the 'file-input'. So the same image can be shown if someone clicks it for once again. 

});

Can you help on this?

If you wish to keep data in other form fields, you can use

HTML

    <input type='file' id='yourid' />

jQuery

    $('#yourid').val('');

this will clear your uploaded file from input tag
