Client side JS and HTML

[hpl]

I have tried to make my GUI dependent on a variable, is this possible with JS? I have used this often in ASP.

<script language="JavaScript">
var test = 2;
if (test==1) {
</script>
<table>
<tr>					
   <td><input type=text name=t1 value=Component size=8></td>
</tr>
</table>
<script language="javascript">
}
</script>
