              $("#buttons").append('&nbsp;&nbsp;<input type="button" value="Import" class="ui-state-default ui-corner-all" onclick="javascript:import_q();" />');

<script type="text/javascript">
   $(function() {
              $("#buttons").append('&nbsp;&nbsp;<input type="button" value="Import" class="ui-state-default ui-corner-all" onclick="javascript:import_q();" />');

       });

function upload_1()
{
   $("#buttons").html('')
}
</script>
<div id="buttons"></div>
<a href="#"  onclick="javascript:upload_1();" >Clear</a>

Works fine for me... How are you initializing the upload_1 function?

$('#buttons').html('');

will replace the innerHTML from the #buttons element.

$('#buttons').replaceWith('');

will replace the element #buttons itself and substitue it with '' (nothing)

Sidenote: There is a typo in your code, a missing ; behind .html().
