select: on change action and retaining values

[shailesh kumar]

Hi All,

I have two combo boxes combo1 and combo2, Combo1 is populated with list of values from database. Upon selecting value in combo1 iam calling javascrpit function which submits form and populates combo2. The problem is since the form is submitted the combo1's selected value is not retained ?, how can I retain the selected value by the user??
Also how can I call two diffrent actions on change diffrent combo boxes ??, any help is appreciated..
I tried this Javascript but this doen't work..

function populateConditions () {   
document.forms[0].action = "/populateConditionTypes";
document.forms[0].submit();
}
function populateConditionValues () {   
document.forms[0].action = "/populateConditionValues";
document.forms[0].submit();
}

Here is my actual code

function populateConditions () {   
document.forms[0].submit();
}
 
function populateConditionValues () {   
document.forms[0].submit();
}
       <html:select property="protocolsNames" size="1" onchange="populateConditions()">
<%

       for(int i=0; i< protocols.length;i++){
   
   out.println("<option value="+ protocols[i].getId()+ " > " + protocols[i].getProtocolName() + "</option>");
}
%>
      </html:select>
 
<html:select property="conditionTypes" size="1" onchange="populateConditionValues()">
  <%

if(protocolConditions !=null){
for(int i=0; i< protocolConditions.length;i++){   
out.println("<option VALUE = " + protocolConditions[i].getId() + ">" + protocolConditions[i].getName() + "</option>");
}
}
%>
      </html:select>

Its simple. On submitting the form based on the values selected in combo1, retreive values for combo2. Then set it the request. For combo1, set both the selected and unselected values again in the request before forwarding it to the view.

Thanks for the reply, but how can I call two diffrent actions, when I select values from combo1 I want to call action1 and on combo2 action2 ??
This javasctipt doesn't work and I looked at the LookupDispatchAction class in struts..but that logic will work with buttons only.
