You may want to use an struts mailing list archive search, and look at this thread:
how to handle requests submitted using java script with a LookupDispatchAction subcalss http://article.gmane.org/gmane.comp.jakarta.struts.user/124351/match=lookupdispatchaction+subcalss+javascript Or a similar thread here: JavaScript problem vs. LookupDispatchAction http://thread.gmane.org/gmane.comp.jakarta.struts.user/14614/focus=14720 Essentially, you need to have the VALUE for the parameter defined in struts-config.xml for the LookupDispatchAction set when the user clicks on the select list element, for example this selection list uses "refreshlist()" in onchange. Here, the Organizations, is a property of the form bean: <html:select property="orgId" onchange='refreshlist()'> <bean:define id="Organizations" name="DependentListForm" property="orgList" type="java.util.Collection"/> <html:options collection="Organizations" property="value" labelProperty="longName"/> </html:select> The refreshlist would be something like this: <SCRIPT language="JavaScript" type="text/javascript"> function refreshlist() { document.forms[0].method.value="refresh"; document.forms[0].submit(); } </SCRIPT> Your action class could then have this: protected Map getKeyMethodMap() { // return Collections.EMPTY_MAP; Map map = new HashMap(); map.put( "dependentlist.refresh", "refreshList"); map.put( "dependentlist.submit", "submit" ); return map; } Your resource file would need the message for "refresh" to map to the dependentlist.refresh: dependentlist.refresh=refresh Your action would need to update the list. I'm not recommending that the list be a property of the form, just saying that the dependentlist, whereever it might be, must be updated: public ActionForward refreshList(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response ) throws Exception { System.out.println("-----refreshList()"); DependentListForm dependency_form = (DependentListForm) form; // NOTE: I put this in the form for testing... dependency_form.refreshStaffList(); return mapping.getInputForward(); } // refreshList -----Original Message----- From: yamilka vallejo ramos [mailto:[EMAIL PROTECTED] Sent: Monday, September 18, 2006 6:59 PM To: user@struts.apache.org Subject: Two drop downs, and I need that the contents of the second dependent on the value selected in the first!!! Hii everyone, I have two drop downs in my jsp page, and I need to the contents of the second dependent on the value selected in the first. To handle this, I need for the first combo box to do a submit when it changes, so that I have a chance to update the second. But I don't know in which part of the Action I most write the code to make update the second drop down, because I'm working with LooKup Dispach Action , and the Hash Map wait a parameter that I don't have because I did't make submit to any button, and there's where I set who it's that parameter example: for me did't work: <html:select property="orgId" onchange='document.forms[0].submit()'> <html:options collection="orgList" property="value" labelProperty="longName"/> </html:select> because I don't know in which part of the Action I most write the code to make update the second drop down, because the ActionClass say that it's waiting a parameter!! please if somebody know how to do that I will presure!! thanks!! --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
