Subject: manipualting a select list from within an event handler
Manipulating checkboxes from withing an onchange event handler works but
I'd like to manipulate a select list like in this code example,
but without luck? I'd appreciate some little help, that would be
fantastic.
Thank's for some input here ;)
kind regards,
Robert
function CheckAuswahl(currForm)
{
a = document.form_addresses.form_protocol.value;
if(a==33554432)
{
for(var x=0; x < currForm.elements.length; x++) {
var y = currForm.elements[x];
y.checked = currForm.form_exch_enabled.checked;
if (y.name == "form_exch_enabled") {
y.checked = true;
//alert(y.name);
}
if (y.name == "form_exch_name") {
if(y.value == "") {
y.value = "ggg";
}
}
if (y.name == "form_exch_pass") {
if(y.value == "") {
y.value = "ggg";
}
}
if (y.name == "form_permitted_rcv") {
//var a=y.createElement('option');
//a.name="TEST";
//y.focus();
y.add('Test',null);
alert(y.size);
}
}
}
}
<td><%=Label_Protocol%></td>
<td>
<%
int intProtocol = Integer.parseInt(Value_Protocol);
%>
<select name="form_protocol"
onchange="CheckAuswahl(this.form)" <%=Label_State%>>
<option <% if ( intProtocol == sysProtocol_ZModem) {%>selected<%}%>
value="<%=sysProtocol_ZModem%>"><
%=Value_Protocol_ZModem%></option>

Robert just looking at it... you passing a form element and the select in
not in one...
Have a look at this example...
http://www.mredkj.com/tutorials/tutorial005.html
and Javascript is a mine field.... so get yourself FireFox at least and the
plugin so you can see the whole DOM and what params are available...
Then make it work just in a normal HTML editor... then stick it in JSP...
else its difficult...
Like for example... look at that example... can you see they making special
allowances for IE... because microsoft are on their own mission.
Google for Javascript stuff... W3 Schools is quite good, but there are tons
of tut sites out there
Javascript is something you really want to use in moderation... its not easy
getting it cross browser compat...
And you'll get crapped out if you ask here ;)
Kinda fun though ;)
