[jQuery] Bug using input type file with IE7

[jQuery] Bug using input type file with IE7


Hi,
I have a problem.
I need clear the field <input type="file"> using jQuery.
The jQuery script is:
$(document).ready(function(){
    $('#clearButton).click(function(){
        $('.file).val('');
    });
});
The Form declaration is:
<form enctype="multipart/form-data" id="form">
    <fieldset>
        <legend>Fields</legend>
        <table>
            <tr>
                <td>File</td>
                <td><input type="file" id="fileField" class="file" /></td>
            </tr>
            <tr>
                <td>Description</td>
                <td><input type="text" id="description" /></td>
            </tr>
            <tr>
                <td><input type="button" id="clearButton" value="Clear"/></td>
            </tr>
        </table>
    </fieldset>
</form>
If use Firefox, this code run correctly, but If use IE7, don't run.
I believe that is a bug.
Somebody can help me?
Thanks.
Renato.
