How to deselct something when selected previously in FileField Django Form?

Question

I have a form which includes filefield to upload some files. Sometimes what happens is at first, I select one file from browse to upload but then i realize i do not want to upload it anymore.How can i make it empty again?? Is it like that once this field is filled it cannot be reverted back to empty??

Thanks in advance

This can be accomplished with javascript.

Quoting Clear upload file input field with jQuery post from electrictoolbox.com:

function reset_html(id) {
    $('#'+id).html($('#'+id).html()); }

$(document).ready(function() {

    var file_input_index = 0;
    $('input[type=file]').each(function() {
        file_input_index++;
        $(this).wrap('<div id="file_input_container_'+
                      file_input_index+'"></div>');
        $(this).after('<input type="button" value="Clear" 
                       onclick="reset_html(\'file_input_container_'+
                       file_input_index+'\')" />');
    });   
});
