How do I populate one Combo box based on input from another

Hi,
I have a dynamic Combo box populated from a database. Now I want to use the onChanged event to dynamically populate a second combo box on the same page.
Any ideas on how to do this?

Here is an example:
let us consider it not coming from the database:
<html>
<head>
<title>New Page 1</title>
<script>
function popSub()
var n = 1;
var mainValue;
mainValue = document.test.main.options[document.test.main.selectedIndex].value ;
if (mainValue=="Age" )
                    document.test.sub.options[n].value = 'below18';
                    document.test.sub.options[n].text = 'Below 18';
                    n =     n + 1;
if (mainValue=="Age" )
                    document.test.sub.options[n].value = 'over18';
                    document.test.sub.options[n].text = 'Over 18';
                    n =     n + 1;
if (mainValue=="Sex" )
                    document.test.sub.options[n].value = 'male';
                    document.test.sub.options[n].text = 'Male';
                    n =     n + 1;
if (mainValue=="Sex" )
                    document.test.sub.options[n].value = 'female';
                    document.test.sub.options[n].text = 'Female';
                    n =     n + 1;
</script>
</head>
<body>
<form method="POST" name="test">
<p><select size="1" name="main" onClick="popSub()">
<option value="Age">Age</option>
<option value="Sex">Sex</option>
<option selected>select one</option>
</select></p>
<p><select size="1" name="sub">
<option value=""></option>
<option value=""></option>
<option value=""></option>
</select></p>
<p><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>
</body>
</html>
If it coming from the database then you have to write the javascript function in jsp as follows:
out.println('<script language="JavaScript">');
out.println('function popSub()');
out.println('{');
out.println('var n = 1;');
out.println('var mainValue;');
out.println('mainValue = document.test.main.options[document.test.main.selectedIndex].value ;');
// start one for loop from 1 to record count
out.println('if (mainValue=="' + valuefrom the resultset + '")');
out.println('{');
out.println("document.test.sub.options[n].value = '" + value from the result set +"';");
out.println("document.test.sub.options[n].text = '"+value from the result set+"';");
out.println('n=n+1;');
out.println('}');
// end of the for loop
finish the javascript function using out.println

Dynamically change the contents of one combo box based on the other

Hi Forum,
I have a question which might have a possibly simple answer. Well anyway help me out since i could not find the simple answer.
I am building an application using Swing and binding with BC4J using JClient. My GUI has combo boxes, grids, editboxes. My requirement is that i should be able to dynamically change the contents of one combo box based on the selected item in trhe previous combo box. For example, when i choose a country in the "country combo box", the "states combo box" should show the list of the states of the selected country.
Now how do i do this using binding. If not, how do i write custom querirs in BC4J layer and return a resultset to the remote application so theat i can populate the dependent combo boxes.
I will appreciate if anyone can help me out in this regard.
Thank You
Sumit

there could be quite a few number of ways of solving this problem.
One way is through event handlers.
taking your example as a model when user selects a country you could fire an action with a flag set to ture. A method will return the states from the DB or your temporary files or what ever and then the true flag will be used in the states combo box rendering.
other way: javascript
this might be a bit clumsy as you will need the states information in a property file and you can get the info as the user selects a country.

Populate 2nd combo box based on value selected in 1st combo box

I am still using Acrobat 6 though I may be upgrading soon to Acrobat 8. I have a form with two combo boxes, the first "state" has values of MN and WI. Based on which value the user picks I would like to populate a "county" combo box with lists of counties that we deal with.
Thanks,
Gene

One can set the option and export value using an arry:<br /><br />// document level script<br />// Master List of Lists <br />// Each entry in this object listeral is the name of a State <br />//Manually enter the State Names into the state field combo box <br />// The associated value is the item list, where each item is a name value pair, [<County> and [county code, zip code]] <br /><br />// state: ["county name", ["county code", "zip code"]]<br />var oStateNames = {MN: [["-", ["", ""] ], <br /> ["St. Louis", ["MNStl", "55001"] ], <br /> ["Carlton", ["MNSCrl", "55002"] ], <br /> ["Pine", ["MNPin", "55003"] ],<br /> ["Cook", ["MNCok", "55004"] ] <br /> ], <br /> WI: [["-", [" ", " "] ],<br /> ["Douglas", ["WIDou", "55005"] ] ,<br /> ["Bayfield", ["WIBay", "55006"] ],<br /> ["Burnette", ["WIBur", "55007"] ],<br /> ["Ashland", ["WIAsh", "55008"] ]<br /> ]<br /> }; <br /><br />//SetCountyEntries() on keystroke entry in state field <br />function SetCountyEntries() <br />{ <br /> if(event.willCommit) <br /> { <br /> // Get the new counties list from the Master List <br /> // Since the selection is being committed, <br /> // event.value contains the State name <br /> var lst = oStateNames[event.value]; <br /> // Clear the county list if there are no counties for the selected state <br /> this.getField("ee.address.county").clearItems();<br /> this.resetForm(["ee.address.code", "ee.address.zip"]);<br /> if( (lst != null) && (lst.length > 0) )<br /> this.getField("ee.address.county").setItems(lst); // set opiton and export value<br /> } <br />} <br />// end document level script<br /><br />For the combo box "ee.address.county" one can create an array from the export value to populate the county code and zip code<br /><br />// custom keystroke for county combo box<br />if(event.willCommit & event.value != "") {<br />// split county and zip codes<br />var aCodes = this.getField(event.target.name).value.split(",");<br />this.getField("ee.address.code").value = aCodes[0];<br />this.getField("ee.address.zip").value = aCodes[1];<br />}<br />// end custom key stroke code

In a tubular form: how do you make one combo box reflect another

For example:
if there are two fields, one with combo box with bread, meat, juice and I select juice, I and the contents of another combo box in another field to say Orange, grape, lemon.
field one field two
bread orange
meat grape
juice lemon
in field one there is just those 3 but in the table representing two there are many such as types of bread and meat and juice, all three.
Hope you can understand this example. Thanks for your help.

Your description is not very clear but looks like you want cascading select lists, where 2nd select list is populated based on value selected in the first select list.
AJAX is a good solution if you are comfortable with it. Since I'm not very familiar with that, I end up using pl/sql.
Someone had asked similar question few days back, and i had provided a detailed answer. You can check it out at:

Problem in popultating combobox based on input from another combobox

i have there combo boxes when i select the first combobox ,based on the input given it must populate the second and based on the input in second combo box it must populate the third one.1->2->3.
Actually i am having a javascript when i select the data in first combo box the information is sent to specified jsp page with parameter using onchange function and the second combo box is poplated based on the first but the third combo box in not populating based on the second.
here is my code:
jsp:
<select name="recrClient" class="selectBox" id="recrClient" onchange="htmlData('BSTSRecuritmentContacts.jsp', 'client='+this.value);">
javascript
function stateChanged()
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
document.getElementById("contacts").innerHTML= xmlHttp.responseText;
else
//alert(xmlHttp.status);
// Will populate data based on input
function htmlData(url, qStr)
if (url.length==0)
document.getElementById("contacts").innerHTML="";
return;
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
alert ("Browser does not support HTTP Request");
return;
if (url=="BSTSRecuritmentContacts.jsp")
url=url+"?"+qStr;
url=url+"&sid="+Math.random();
xmlHttp.onreadystatechange=stateChanged;
xmlHttp.open("GET",url,true) ;
xmlHttp.send(null);
if i use the same method populating the third combo box, this is not working
please reply me and thanks in advance

Hi there,
What about this:
Create a multicube with 0PA_C01 and 0PE_C01 and then you create one key figure with the total of employes (that comes from 0PA_C01) and another key figure with the total number of employes that had training (that comes from 0PE_C01) and finally you create a calculated key figure at query level that subtracts the first key figure by the second, i.e., the total number of employees - the employees that had training.

How do I populate one dropdown list based on the selection in another dropdown list?

I have one dropdown list that has 21 choices. Depending on the selection of those 21 choices, I have another dropdown list that will select a different subset of choices from a pool of 96 choices. How do I get this to happen?

How to use one Combo Box to control Two spreadsheet/charts in Web Analysis

In Web Analysis panel, I have one data grid and one chart (two different data sources). I would like to have one combo box, e.g. Q1, Q2, Q3, Q4, in the selection (drop-down). When I select Q1, I would like to show Jan, Feb, Mar, Q1 ( ICHILDREN(Q1)) in my chart, and also only Q1 in my data grid.
Any suggestions?
Thanks

I believe you can do this. For example you want to have a Chart and Graph linked to a drop down for products. When you select a product, the two POV's will change on the reports.
Look at Panels in WA. I create a report with three panels. Make the first panel top aligned, the second top aligned and the third stretched. This should make the report "stretchy". Then add your dropdown to one panel and your reports to the other two panels.
Finally link the reports to dropdown using the re-linking technique mentioned in the previous post.
Hope this helps.

the brand old dependent combo issue..
as far as i know i could tell you for every two days a similar post is being posted here on the same thread..
you could have taken a look of them....
Anyways there are many ways of doing it....
In the days when XmlHttpRequest Object was not invented ppl used to achieve this using Hidden iframe and then updating parent frame dropdown by calling a javascript function onload of the page. or by auto refershing the page after saving the form state inside the scope of session.
However,using XmlHttpRequest Object (AJAX) nowdays is one of the smater ways of acheving tasks as these.
checkout one such examples where i've posted a similar example in the last reply

How can I make the combo box turn to the value of black.

When the show button is pressed (and not before), a filled black square should be
displayed in the display area. The combo box (or drop down list) that enables the user to choose the colour of
the displayed shape and the altering should take effect immediately.When the show button is pressed,
the image should immediately revert to the black square, the combo box should show the value that
correspond to the black.
Now ,the problem is: after I pressed show button, the image is reverted to the black square,but I don't know
how can I make the combo box turn to the value of black.
Any help or hint?Thanks a lot!

How to display data from a recordset based on data from another recordset

How to display data from a recordset based on data from
another recordset.
What I would like to do is as follows:
I have a fantasy hockey league website. For each team I have
a team page (clubhouse) which is generated using PHP/MySQL. The one
area I would like to clean up is the displaying of the divisional
standings on the right side. As of right now, I use a URL variable
(division = id2) to grab the needed data, which works ok. What I
want to do is clean up the url abit.
So far the url is
clubhouse.php?team=Wings&id=DET&id2=Pacific, in the end all
I want is clubhouse.php?team=Wings.
I have a separate table, that has the teams entire
information (full team name, short team, abbreviation, conference,
division, etc. so I was thinking if I could somehow do this:
Recordset Team Info is filtered using URL variable team
(short team). Based on what team equals, it would then insert this
variable into the Divisional Standings recordset.
So example: If I type in clubhouse.php?team=Wings, the Team
Info recordset would bring up the Pacific division. Then 'Pacific'
would be inserted into the Divisional Standings recordset to
display the Pacific Division Standings.
Basically I want this
SELECT *
FROM standings
WHERE division = <teaminfo.division>
ORDER BY pts DESC
Could someone help me, thank you.

Assuming two tables- teamtable and standings:
teamtable - which has entire info about the team and has a
field called
"div" which has the division name say "pacific" and you want
to use this
name to get corresponding details from the other table.
standings - which has a field called "division" which you
want to use to
give the standings
SELECT * FROM standings AS st, teamtable AS t
WHERE st.division = t.div
ORDER BY pts DESC
Instead of * you could be specific on what fields you want to
select ..
something like
SELECT st.id AS id, st.position AS position, st.teamname AS
team
You cannot lose until you give up !!!

How to create a new row for a VO based on values from another VO?

Hi, experts.
in jdev 11.1.2.3,
How to create a new row for VO1 based on values from another VO2 in the same page?
and in my use case it's preferable to do this from the UI rather than from business logic layer(EO).
Also I have read Frank Nimphius' following blog,but in his example the source VO and the destination VO are the same.
How-to declaratively create new table rows based on existing row content (20-NOV-2008)
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/13-create-with-params-169140.pdf
I have tried:
1.VO1(id,amount,remark1) and VO2(id,amount,remark2) are based on different EO,but render in same page,
2.Drag and drop a Createwithparams button for VO1(id,amount,remark),
3.add: Create insertinside Createwithparams->Nameddata(amount),
4.set NDName:amount, NDValue:#{bindings.VO2.children.Amount}, NDtype:oracle.jbo.domain.Number.
On running,when press button Createwithparams, cannot create a new row for VO1, and get error msg:
<Utils> <buildFacesMessage> ADF: Adding the following JSF error message: For input string: "Amount"
java.lang.NumberFormatException: For input string: "Amount"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
Can anyone give some suggestions?
Thanks in advance.

Hi,CM,
I'm really very appreciated for your quick reply! You know, today is Saturday, it's not a day for everyone at work.
My principal requirement is as follows:
1.select/check some rows from VO2, and for each selection create a new row with some attributes from VO2 as default values for VO1's corresponding attributes, and during this process the user may be cancel/uncheck or redo some of the selections.
--so it's better to implement it in UI rather than in EO.
2.it's better to implement this function with declarative way as in Frank Nimphius' blog.
--little Jave/JS coding, the better. I only have experience in ORACLE FORMS, little experience in JAVA/JS.
In order to get full information for the requirements of my use case, can take a check at:
How to set default value for a VO query bind variable in a jspx page?
(the end half of the thread: I have a more realworld requirement similar to the above requirement is:
Manage bank transactions for clients. and give invoices to clients according to their transaction records. One invoice can contain one or many transactions records. and one transaction records can be split into many invoices.

I want to allow users to be able to select multpile catagories for the question, like making one both math and science (which right now is completely possible)
I then want another column that says who the problem is assigned to. Bob is good at math, Joe at science, Jill at histroy, Jenn at English, and Billy handles everything else.
1) Is there a way that the task can be automatically assigned to my math expert Bob when I specify that the item I am adding is a math problem?
2) If I make a problem both math and science, can the task be assigned to both Bob and Joe?
Thanks in advance!

Hi,
According to your post, my understanding is that you wanted to assign a task based on information from another column.
To assign task to multiple users, you need to:
Create a workflow and add action: Start Approval Process.
Click these user, select the Group, change One or a time(serial) to
All at onec(paralle).
Right click the action, select Properties, click ExpandGroups, change No to
Yes.
Then you can assign task to each member of the group.
I recommend to follow the steps as below to achieve what you want:
Create a custom list, add columns: Question Type(Choice); Assigned to(Person or Group).
Create a workflow associated the list.
Add conditions and action as below:
Then the task can be automatically assigned to 123 when the item is a math problem.
In addition, if you make a problem both math and science, the task can be assigned to both 456 and 789.
You can add other conditions to satisfy all the requirements.
