Combo box in javascript

I have a combo box (combo1), and on changing the value selected in it, a second combo box (combo 2) is displayed on the screen.
I need to be able to add some java script code for Combo2, as depending on the value selected in it, some further action has to be done.
All the code i've tried searching for so far, uses the HTML version of combo box, and accesses the value in java script using the line "document.formname.OPTION.[selectedindex].value".
How would i do the same for a JSF combo box, in java script?
Thanks in advance :)

hi.. thanks for the response.. i did as u suggested but i got the following error : "document.all.menu8 is null or not an object "
The code for my combo box is as follows:
<h:selectOneMenu styleClass="selectOneMenu" id="menu8" onchange="display()">
<f:selectItem itemLabel="select" itemValue="select" />
<f:selectItem itemLabel="option 2" itemValue="op2" />
<f:selectItem itemLabel="option 3" itemValue="itemValue3" /></h:selectOneMenu>
<div id="op2" style="DISPLAY: none">The following is the java script snippet:
<script language="javascript">
     function display()
          document.all.op2.style.display='none';
          document.all.itemValue3.style.display='none';
          var d=document.all.menu8.getElementById(menu8);
          var name=d.options[d.selectedIndex].value;
          if(name!='select')
           eval("document.all."+name+".style.display='' ");
          </script>Is it that the 'div' tag is incompatible in this case?

How validate a combo box generated for a selectOne on javascript

Hi!!
I have a question!
i need how validate a combo box on javascript if this is generated by selectOne
for example:
<tr>
<td width="150px"><b>Cantidad a elegir:</b></td>
<td><f:selectOne att='idisponibilidad.cantidadElegir' type='combo'/></td>
</tr>
this is an form and this generates in the name of the select:
<select name="$FO$idisponibilidad.cantidadElegir">
<option value="0">..</option>
<option value="4">..</option>
</select>
but now I try to do this:
document.form.$FO$idisponibilidad.cantidadElegir.value
and obviously does not work!!!
someone knows how to validate
Thanks!!!

Taking Mark's Code .. add an id
<select id="personGender" <f:fieldName att="person.gender"/>>
<c:forEach var="gender" begin="0" items="${genders}" varStatus="status">
<c:choose>
<c:when test="${person.gender == gender}">
<option value="<c:out value="${gender}"/>" selected="true"><c:out value="${gender}"/></option>
</c:when>
<c:otherwise>
<option value="<c:out value="${gender}"/>"><c:out value="${gender}"/></option>
</c:otherwise>
</c:choose>
</c:forEach>
</select>
Add an id to above code. In your submit button write a function on onclick event .. like onclick="submitForm()"
Write the functions as :
function submitForm(){
     if(validateFileds()){
document.<your form id>.submit();
function validateFields(){
if (isEmptyCombo ('personGender')) {
               alert ( "'Selecting a gender is mandatory" );
               focus('personGender');
               return false;
function isEmptyCombo (id) {
     var combo = document.getElementById(id);
     return combo != null && combo.options[combo.selectedIndex].value == "";
function focus (id) {
     if (document.getElementById(id)) document.getElementById(id).focus();
Thanks,
Karmaresh

Adobe Acrobat 9: Javascript array populated combo box - Selected answer will not save

I have a combo box on one of my forms that is populated using a Javascript array. The combo box is populating just fine, but when an item is selected from that combo box, the selected item does not save when the user saves the document. Any suggestions as to what the problem is and how it can be corrected? I am a loss as to where to even begin looking. Any help is greatly appreciated.
Thank you.

Newb deserving assistance with Adobe Javascript (check boxes and combo boxes)

Hi, I'm a newb when it comes to javascript (using adobe acrobat pro 6.0).
I am working on a form that will allow me to autofill checkboxes based off of information chosen. Ideally, I would like to have a selection from a combo box autofill/auto checkmark check boxes. Alternatively, I would be willing to just have different selections presented with check boxes that when filled, would auto checkmark other check boxes (I know how to do this one, but I am not sure how to clear the check boxes if the initial one is unchecked).
I have the action button tied to the mouse up function. This just errors out.
var Citrix = this.getField("Citrix")
var Appro = this.getField("Appro")
var SAS = this.getField("SAS")
if (event.target.value=="Yes") {
Citrix.checkThisBox = true
Appro.checkThisBox = true
SAS.checkThisBox = true
else {
Citrix.checkThisBox = false
Appro.checkThisBox = false
SAS.checkThisBox = false
I have this that works, but I don't know how to clear the buttons when "Associate" is unchecked.
if(this.getField("Associate").isBoxChecked(0));
this.getField("Citrix").checkThisBox(0, true);
this.getField("Appro").checkThisBox(0, true);
this.getField("SAS").checkThisBox(0, true);
The other way I was working on it, was to use a combo box to autofill/checkmark check boxes. But this code doesn't work either.
function calculateTextField()
// get the value of the combo box
var comboValue = this.getField("Select").value;
// get the state of the checkbox
var isChecked = (this.getField("Citrix").value == "Yes");
var textFieldValue = "";
console.println(comboValue);
if (isChecked)
if (comboValue == 0)
textFieldValue = "";
if (comboValue == "Associate")
(this.getField("Citrix").value == "Yes");
else if (comboValue == "Specialist")
(this.getField("Citrix").value == "Yes");
else if (comboValue == "Team Leader")
(this.getField("Citrix").value == "No");
else
(this.getField("Citrix").value == "No");
else
textFieldValue = "";
this.getField("Select").value = textFieldValue;
Can anyone please assist me with this?
Thanks,
Chris

Hi Gene,
Thank you for the response. Are you saying that my initial formula should look more like this; ?
var Citrix = this.getField("Citrix")
var Appro = this.getField("Appro")
var SAS = this.getField("SAS")
if (event.target.value=="Yes") {
Citrix.checkThisBox = true
Appro.checkThisBox = true
SAS.checkThisBox = true
else {
if (event.target.value=="Off")
Citrix.checkThisBox = true
Appro.checkThisBox = true
SAS.checkThisBox = true
Thanks,

Show text box from one combo box selection

Total newb here and need help. I tried searching for a javascript to copy/paste, but without any luck. I am using Acrobat Pro 9.2.0. If you could help me out with the javascript or with directions on how to make the following be accomplished, I would be greatly appreciative.
I am creating a fillable PDF and currently have a combo box that is labeled "Internship Satisfied By" with the options of "TCoB PDP", "MRKTNG 4185", and "Other College". I would like a hidden text box (where the end user can fill in to explain) to become visible only when the end user selects the "Other College" option, but stay hidden for the other selections. The hidden text box is labeled "Internship Explained".
Thanks in advance! Jarrod

Use this code as the combo box's validation script:
if (event.value == "Other College") {
getField("Internship Explained").display = display.visible;
} else {
getField("Internship Explained").display = display.hidden;

Can I attach a specific action to a choice in a list box or combo box?

I have a list of 26 sports that I would like people to choose from--in either a list box or combo box or any other tool that would work best. When they choose a particular sport, I would like another PDF to appear with the roster for that sport for this year, allowing them to check off certain players. Is this possible? Everything I see is in javascript or some other language that I don't know.
Thanks.

I am piling on Gary's question, as I would like to know the answer as well. But first a little more color in case there is another way to do this....
When I get an email, I usually take some sort of action. I currently do not have a good way to note the actions I have taken against any particular email. This is why I want to know how to attach a note or a To Do to a particular email. I thought the To Do list would work, but when I type a To Do with a particular email sometimes it appears in the list and sometimes it doesn't.
So my goal is to have a way to create a history of action against a particular email.
Gary, I hope this is a valuable extension to your request as opposed to a diversion from your original intent. With any luck together we'll get a bit more traction for your request.
Thanks.

Is it possible to have a combo box change an image on a form? How do you do it?

I would like to have an area in one of my PDF forms where a combo box with 8 items changes an image near the combo box. 8 items 8 images. if you select item 3 in the list then image 3 is displayed in the image area or field.
Is this possible? Might someone guide me as to what steps are necessary. I can make this happen with web, asp, c++ etc. I just don't know how to do it in adobe if it's possible.
example below.
Any help or guidence is appreciated.

Here's a sample that demonstrates what you want: https://acrobat.com/#d=It35dD4zaX5QM--Pv36F-Q
The buttons on the right hand side would normally be hidden and you can use anything you want for their icon, even though in this case it's just text. You'll have to study the JavaScript to see how it works. There are two functions in a document-level JavaScript, one of which is called from the combo box's Keystroke event. Also, note the export values of the items in the list and how the script uses them.

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

While selecting value from combo box in one frame, based on the selection..

Hi friends,
can someone help me out on a issue as it follows:-
iam developing an application where Iam using xsl,html,javascript and xml.
There is no existense of Database at all. data is read from xml.
now,
In a window there are 3 frames. In the 1st frame combo box is there.
Based on the selection in the combo box data will be displayed in the 2nd frame.
now onchange or onselect methods not giving the expected result.
actually,in the the xsl which is having 3 frames,the 1st and 3rd frame
calling src="abc.xml" and src="abc.xml"which are static.
but in the 2nd frame the data need to be changed dynamically.
I have given frame name="frame_ExchangeDetails2" rows="3%" src="cc_marketWatch_02.xml"/>
usually data dynamically comes from database.but here i have to refer xml file
something like [window.href.location="abc.xml"]
but the problem is when you refer supose:-
<frame name="frame_ExchangeDetails2" rows="3%" src="cc_marketWatch_02.xml"/>
the frame is having static page,though there are functions in javascript which are called in onload and onchange.which are not working.
I have tried putting if condition like:-
if(document.abc.fieldname.value=='6'
{ window.location.href = "cc_custLookUpData-mobileno.xml";
so that it could go to the repective page.
but it is not working.
so what should i do if I select from combo box in one frame and based on the selection xml/html page will be displayed in the 2nd frame.
if anybody has google account i can forward the zip file so it will be easier to understand.
Regards

How to Add/Concatenate to a text field, values selected in a combo box

I have a combo box form field that allows the user to select a value from a list and click on an Add button. The Add button should add/concatenate the vaue selected to a text field in order to create a list of values selected. I'm not sure how to do this using Javascript in Acrobat? I know I need to add the javascript to the Add button's Mouse Up action. Any help would be greatly appreciated. Thanks!

Let's say the text field's name is "Text1", and the combo is called "Combo1". You can then use this code as the MouseUp script of the Add button:
var f1 = this.getField("Text1");
var f2 = this.getField("Combo1");
if (f1.value=="") f1.value = f2.value;
else f1.value = f1.value + ", " + f2.value;

Combo Box in JSP

Hi,
I am a student and working on a class project. In my application at some point, I need to provide a combo box where user can select multiple values and those values should automatically be printed in a text area provided below the combo box. Is this possible?

The Only Way By which U can achieve this is by a scripting languages like javascript,vbscript......
Nvr By JSP(Is nothing but a servlet under execution @ background of webserver) as it is meant for Server Side Programming Surely not for Client Side Dynamic Action.
Make use of <select> with multiple property set to true....
and then.... append selected values in the second textbox.
You may go throgh the code given below
c whether that can help u out.....
CLIENT.JSP

function change(){
var x=document.getElementById("mySelect")
document.getElementById("result").value = ""
for(var i=0;i < x.length;i++){
if(x.options.selected == true)
document.getElementById("result").value = document.getElementById("result").value + " "+x.options[i].value
