[jQuery] AutoComplete

[jQuery] AutoComplete

Hi Experts,
I have this autocomplete script;
 <span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">   $("#operator").autocomplete("bright/auto.php",</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);">
<span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">    {</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);"><span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">        delay:10,</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);">
<span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">        lineSeparator: "^",</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);"><span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">        cacheLength: 10,</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);">
<span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">        matchSubset:1,</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);"><span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">        matchContains:1,</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);">
<span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">        formatItem: formatItem,</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);"><span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">        autoFill: false</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);">
<span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">    }).result(function(a,data,c) {</span><br style="font-family: courier new,monospace; color: rgb(0, 102, 0);"><span style="font-family: courier new,monospace; color: rgb(0, 102, 0);">});</span>
Which works perfect. My question is i want to be able to display a DIV if the result for autocomplete is null.
Do anyone know how to go about this?
