Hi there
Using Oracle Application Express:
Have 4 items (4 select lists, with defaults '%')
Lists are grouped by 2 lists each e.g. project number (list1), then Order No for project (based on list1)
What I am trying to do:
select from the 2 lists, click on url link, opens another page.
for both groups of lists
does not meet the first condition...





--it works if i use individual codes for each conditions
--Html Header
<script language="JavaScript" type="text/javascript">
function callMyPopup (formItem1,formItem2) {
    var formVal1 = document.getElementById(formItem1).value;
    var formVal2 = document.getElementById(formItem2).value;
    var url;
  url = 'f?p=&APP_ID.:32:&APP_SESSION.::::P32_ARCHIVEPROJECT,P32_ARCHIVEPO:' + formVal1 + ',' + formVal2;
  w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
  if (w.opener == null)
  w.opener = self;
  w.focus();
  }
</script>
 
 
--Post Element Text - second list
<a href="javascript:callMyPopup(
'P19_ARCHIVEPROJECT',
'P19_ARCHIVEPO');">Preview Report</a>
---------------------------------------------------------------------------------------------------------------
--always goes to second condition--work in progress
 
<script language="JavaScript" type="text/javascript">
 
if (document.getElementById('P16_ARCHIVEPROJECT').value != '%') 
 
{
function callMyPopup (formItem1,formItem2) {
    var formVal1 = document.getElementById(formItem1).value;
    var formVal2 = document.getElementById(formItem2).value;
    var url;
  url = 'f?p=&APP_ID.:32:&APP_SESSION.::::P32_ARCHIVEPROJECT,P32_ARCHIVEPO:' + formVal1 + ',' + formVal2;
  w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
  if (w.opener == null)
  w.opener = self;
  w.focus();
  }
 
} 
else if (document.getElementById('P16_PROJECT').value != '%')
{
  function callMyPopup (formItem1) {
    var formVal1 = document.getElementById(formItem1).value;
    var url;
  url = 'f?p=&APP_ID.:16:&APP_SESSION.::::P16_PROJECT:' + formVal1;
  w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
  if (w.opener == null)
  w.opener = self;
  w.focus();
  }
}
else
  {
  document.write("<b>Hello World!</b>");
  }
 
</script>

I'm not sure what you mean by this...

"for both groups of lists does not meet the first condition..."

You'r using an odd syntax, you check the condition and defines a fucntion in both branch.
Try with a code refactorec like that
<script language="JavaScript" type="text/javascript">
function callMyPopup (formItem1,formItem2) {
   if (document.getElementById('P16_ARCHIVEPROJECT').value != '%') {
      var formVal1 = document.getElementById(formItem1).value;
      var formVal2 = document.getElementById(formItem2).value;
      var url = 'f?p=&APP_ID.:32:&APP_SESSION.::::P32_ARCHIVEPROJECT,P32_ARCHIVEPO:' + formVal1 + ',' + formVal2;
      var w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
      if (w.opener == null)
         w.opener = self;
      w.focus();
   } else if (document.getElementById('P16_PROJECT').value != '%') {
      var formVal1 = document.getElementById(formItem1).value;
      var url = 'f?p=&APP_ID.:16:&APP_SESSION.::::P16_PROJECT:' + formVal1;
      var w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
      if (w.opener == null)
         w.opener = self;
      w.focus();
   } else {
      document.write("<b>Hello World!</b>");
   }
}
</script>

Hi there
Thanks for comments:  Tried the code, does not work.  Generates errors.
Explain
group1
list1
list2 (filter based on list1) (popup page1) (you must select list1,2 to get popup page1)

group2
list3
list4 (filter based on list3) (popup page2) (you must select list3,4 to get popup page2)

see code ..






Cond
if i create a simple test, to test the condition for group 1, it works
--it works
<script language="JavaScript" type="text/javascript">
function test2()
{
if (document.getElementById('P19_ARCHIVEPROJECT').value == "%")
{
alert("yes " + document.getElementById('P19_ARCHIVEPROJECT').value); 
}
else if (document.getElementById('P19_ARCHIVEPROJECT').value !== "%")
{
alert("no " + document.getElementById('P19_ARCHIVEPROJECT').value); 
}
}
</script>
 
--take it to next stage, adding function popup, get errors
<script language="JavaScript" type="text/javascript">
function test2(formItem1,formItem2)
{
var formVal1 = document.getElementById(formItem1).value;
var formVal2 = document.getElementById(formItem2).value;
var url;
if (document.getElementById('P19_ARCHIVEPROJECT').value !== "%")
{
  function callMyPopup (formVal1,formVal2) 
 
{  
  url = 'f?p=&APP_ID.:32:&APP_SESSION.::::P32_ARCHIVEPROJECT,P32_ARCHIVEPO:' + formVal1  + ',' + formVal2 ;
  w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
  if (w.opener == null)
  w.opener = self;
  w.focus();
}
 
 
}
 
}
else if (document.getElementById('P19_ARCHIVEPROJECT').value == "%")
 
{
alert("no " + document.getElementById('P19_ARCHIVEPROJECT').value); 
}
}
</script>

what error is displayed? Without your html is hard to do local tests.

var formVal2 = document.getElementById(formItem2).value;
var url;
  url = 'f?p=&APP_ID.:32:&APP_SESSION.::::P32_ARCHIVEPROJECT,P32_ARCHIVEPO:' + formVal1  + ',' + formVal2 ;
