problems with onchange

Hello anybody has an idea on how to display textbox when selecting item in the select box.

heres my code...


<script type="text/javascript">

function displaytext()
{
var actiontype = document.forms['actions']['eventcat'];
var schedule = document.forms['actions']['date3'];

if (actiontype.options[actiontype.selectedIndex].value == "1")
{
schedule.style.display = 'inline';
}
else if (actiontype.options[actiontype.selectedIndex].value == "2")
{
schedule.style.display = 'inline';
}
else
{
schedule.style.display = 'none';
}
}

</script>




<?php
echo '<form name="actions">
<tr><td>Action Type</td>
<td>'.html_select("eventcat",0,array_of("eventcat"),"",$actype).'</td>
</tr>
<tr><td>Interview Schedule</td>
<td>
<input type="text" name="date3" id="sel3" size="20" readonly value="'.$rowa[edate].'"><input type="reset" value=" ... "
onclick="return showCalendar(\'sel3\', \'%Y-%m-%d\');">
</td>
</tr>
</form>';
?>


When I click an item in the select box the Interview Schedule row will display.. tnx..

$types = array ('Default', 'Type 1', 'Type 2');
echo "<form method='post'>";
echo "<select size='1' name='my_choice' onChange='this.form.submit();'>";
foreach ($types as $k => $v) {
$sel = ($k == $_POST['my_choice']) ? ' selected ' : '';
echo "<option $sel value='$k'>$v</option>";
}
echo "</select>";
if ($_POST['my_choice'] == 2) {
echo " Type 2 : <input type='text' name='data2'>";
} else if ($_POST['my_choice'] == 1) {
echo " Type 1 : <input type='text' name='data1'>";
} else {
echo " Default : <input type='text' name='data2'>";
}
echo "</form>";

Ive got this example..

<script type="text/javascript">

function toggleField(val) {
var o = document.getElementById('datetext');
var c = document.getElementById('dbutton');
(val == '1' || val=='2')? o.style.display = 'block' : o.style.display = 'none';
(val == '1' || val=='2')? c.style.display = 'block' : c.style.display = 'none';
}


</script>

<form action="" method="post">
'.html_select("eventcat",0,array_of("eventcat"),"",$actype,"toggleField(this.value);").'
<input type="text" name="datetext" id="datetext" style="display: none;">
<input type="reset" name="dbutton" id="dbutton" style="display: none;">
</form>

my question is how can i combine the "datetext" and "dbutton" in variable.

tnx

well, ive tried your php version of onchange, but the problem is when it loads the values of my other textboxes will disappear and also the item that I clicked on the select box will back to the default..

heres what i did..

$types = array ('1', '2', '3','8');
echo "<form method='post'>";
echo ''.html_select("eventcat",0,array_of("eventcat"),"",$actype,"this.form.submit();").'';
if (($_POST['eventcat'] == 1) || ($_POST['eventcat'] == 2) || ($_POST['eventcat'] == 8))
{
echo " Interview Schedule : <input type='text' name='data2'>";
}

echo "</form>";

solved?

Yeah Ive solved it already.. your absent yesterday...

Anyway.. Thanks a lot...
