how to setup button to get file input back to being blank
<pre><code>function insertQuestion(form) {   

    var $tbody = $('#qandatbl &gt; tbody'); 
    var $tr = $("&lt;tr class='optionAndAnswer' align='center'&gt;&lt;/tr&gt;");
 var $image = $("&lt;td class='image'&gt;&lt;/td&gt;");


 $weight.append($weightText);

        });

                var $imagefile = $('&lt;input /&gt;')
            .attr({
                type: 'file',
                name: 'imageFile',
                class: 'imageFile'
            });

            $image.append($imagefile);

                var $imageclear = $('&lt;input /&gt;')
            .attr({
                type: 'button',
                name: 'imageClear',
                class: 'imageClear',
                value: 'Clear File'
            });

$tr.append($image);
$tbody.append($tr); 

}
</code></pre>

<p>In the code above I have a file input and a button. What my question is, is that I want the button to be set up so that when the user clicks on the button, it removes the file url already selected by the user from the file input so that the file input could go back to being blank, how can I do this?</p>
