Hi!
i have these components:
<html:select name="orderBean" property="data.payingType"
onchange="javascript:disable();">
<html:options name="orderBean" property="payingTypes" />
</html:select>
<html:select name="orderBean" property="data.payments">
<html:options name="orderBean" property="paymentsList" />
</html:select>
<html:text maxlength="25" size="15" name="orderBean"
property="data.billToName" />
i would like that when the user chooses a specific value in data.payingType
- it would disable/enable the other html:select and html:text.
i wrote this function:
<script type="text/javascript">
function disable(){
var sel = document.getElementsByName('data.billToName')[0];
sel.options[sel.selectedIndex].value;
alert(sel);
}
<script>
but i get an error:
sel.selectedIndex is undefined.
how can i do it please?
Thanks!
