Re: dynamic drop-down changes without calling action class using session

[Vic Cekvenich]

Several ways:
One is a 2 dimensional array put is scope by Struts, for JavaScript use.
And a cool way:
XML-RPC via JavaScript.
Cheat Sheet page on baseBeans.com has a link on specific example, or you 
can google on XML-RPC. (I realy think Scripting and XML-Type-Services is 
going to be big!!!!)

Thanks, 

  But, Right now I am using the following way with javascript,

   eg. First drop down,
            <html:select property="system" style="width:150px" onchange="return call(this)" 
styleId='sys1' styleClass="text">
               <html:options collection="systemids1" property="value" 
labelProperty="label"/>
                        </html:select>
      Second drop-down,
            <html:select property="subsystem" style="width:150px;display:'none'" onchange="pops(this)" styleId='subsys1' styleClass="text"> 
              <html:options collection="subsystemids1" property="value" 
			labelProperty="label"/> </html:select>

             <html:select property="subsystem" style="width:150px;display:'none'" onchange="pops(this)" styleId='subsys2' styleClass="text"> 
              <html:options collection="subsystemids2" property="value" 
		labelProperty="label"/> </html:select>

    Depends on first drop-down selection i am hiding subsystem1 or subsystem2. If suppose the first drop-down has lengthy list then my logic needs more drop-downs. It increase the code side and maintenance..Is there any way to do that?..

Thanks,
Kaja

using session
You'll have to do more than store the data for your drop-down in the 
session, if you don't want another request to go to the server - you'll 
have to store all the data for your drop-downs in JavaScript and use 
JavaScript to dynamically populate the drop-downs as selections change.
