<script language=javascript>
function changebuilding (which) {
sel_var = which.selectedIndex
<?
$sql_query = "select distinct room
from general.room_info
where building='$variable' group by level asc";
$sql_result = mysql_query($sql_query) or die (" Can't execute the
query");
$i=0;
while ($row = mysql_fetch_array($result_sec_level))
print ("ar[".$i++."] = \"".$row[0]."\";\n");
?>
for (i=0; i < ar.length; i++) {
option = new Option(ar[i])
document.myform.room.options[i]=option
}
}
</script>
<body>
<form name=myform>
Building : <select name=building onchange=changebuilding(this) >
<option>1</option>
<option>2</option>
<option>3</option>
</select>
Room : <select name=room >
</select>
</form>
</body>
I can pass the variable in building to $variable by submit button
but I want to pass the sel_var variable to $variable and dynamic update
the content in room.
