Hi,
Basically, I would like to call a method that I have written in the page java bean, or in the session bean, or application bean, or an external bean, from the javascript events (mouseover, on click, etc...) of a ui jsf component. I.e., I would like to take an action when a user clicks in a column in a datatable.

How to call jpf controller method from javascript

Can any one help me how to call pageflow controller method from JavaScript.\
Thanks.

Accessing a particular pageflow method from Javascript is directly not possible unless we do some real funky coding in specifying document.myForm.action = xyz...Heres what I tried and it did not work as expected: I found another workaround that I will share with you.
1. In my jsp file when I click a button a call a JavaScript that calls the method that I want in pageflow like this: My method got invoked BUT when that method forwards the jsp, it lost the portal context. I saw my returned jsp only on the browser instead of seeing it inside the portlet on the page of a portal. I just see contents of jsp on full browser screen. I checked the url. This does make the sense. I do not see the url where I will have like test1.portal?_pageLabe=xxx&portlet details etc etc. So this bottom approach will notwork.
document.getElementById("batchForm").action = "/portlets/com/hid/iod/Batches/holdBatch"; // here if you give like test1.portal/pagelable value like complete url...it may work...but not suggested/recommended....
document.getElementById("batchForm").submit;
2. I achieved my requirement using a hidden variable inside my netui:form tag in the jsp. Say for example, I have 3 buttons and all of them should call their own action methods like create, update, delete on pageflow side. But I want these to be called through javascript say for example to do some validation. (I have diff usecase though). So I created a hidden field like ACTION_NAME. I have 3 javascript functions create(), update() etc. These javascripts are called onclick() for these buttons. In thse functions first I set unique value to this hiddent field appropriately. Then submit the form. Note that all 3 buttons now go to same common action in the JPF. The code is like this.
document.getElementById("ACTION_NAME").value = "UPDATE";
document.getElementById("batchForm").submit.
Inside the pageflow common method, I retriev this hidden field value and based on its value, I call one of the above 3 methods in pageflow. This works for me. There may be better solution.
3. Another usecase that I want to share and may be help others also. Most of the time very common usecase is, when we select a item in a drop bos or netui:select, we want to invoke the pageflow action. Say we have 2 dropdown boxes with States and Cities. Anytime States select box is changed, it should go back to server and get new list of Cities for that state. (We can get both states and cities and do all string tokenizer on jsp itself. But inreality as per business needs, we do have to go to server to get dynamic values. Here is the code snippet that I use and it works for all my select boxes onChange event.
This entire lines of code should do what we want.
<netui:anchor action="selectArticleChanged" formSubmit="true" tagId="selectPropertyAction"/>
<netui:select onChange="document.getElementById(lookupIdByTagId('selectPropertyAction',this )).onclick();" dataSource="pageFlow.selectedArticleId" >
<c:forEach items="${requestScope.ALL_ARTICLE}" var="eachArticle">
<%-- workshop:varType="com.hid.iod.forms.IoDProfileArticleRelForm" --%>
<netui:selectOption value="${eachArticle.articleIdAsString}">${eachArticle.articleItemName}</netui:selectOption>
</c:forEach>
</netui:select>
See if you can build along those above lines of code. Any other simpler approches are highly welcome.
Thanks

Invoking Applet methods from Javascript for Netscape 6

Hi,
I am trying to invoke an applet method from javascript, but it is failing with Netscape 6 browser:
I am doing it the following way-
function test(form)
var i = document.myapplet.getname();
where myapplet is the name of the applet and getname is a method within the applet. This is
working with Ie but not with netscape 6.
I would appreciate it if someone could tell me how should I invoke the applet method for netscape browsers.
Thanks.
Jay Srin.

Not working with NS 6 - and will not i guess till they upgrade to Mozilla Version 1.0 - Live Connect is not implemented 100% correct yet - if you want you can download the 7.0 Pre Release Netscape - since its using mozilla 1.0 it should work , see :

How to expose plugin methods to JavaScript ?

It's your plugin - you can do whatever you want and expose them however you wish.

Right. If you are using delegated privs and sudo, make sure that sudo is configured to pass on the PERL5LIB and ORACLE_HOME environment variables at least.

How to access the controller method from javascript onclick event?

Hi All,
I am totally new to development. And I got struck in calling a controller method from javascript function.
I have no idea about ajax and all those things. Please can anyone help me to solve this issue!
Thanks in advance.

Hi,
As I know, you can use jQuery to do this, here is an example.
Example of your Controller Method.
[HttpPost] // can be HttpGet
public ActionResult Test(string id)
bool isValid = yourcheckmethod(); //.. check
var obj = new {
valid = isValid
return Json(obj);
and this would be your javascript function.
function checkValidId(checkId)
$.ajax({
url: 'controllerName/Test',
type: 'POST',
contentType: 'application/json;',
data: JSON.stringify({ id: checkId }),
success: function (valid)
if(valid) { //show that id is valid }
else { //show that id is not valid }
If you have further issues, I would suggest you move to MVC forum, it is appropriate and more experts will assist you.

Calling a jsp:useBean method in Javascript

Hi,
I want to call a jsp:useBean method in Javascript. Like:-
<jsp:useBean id="StringEscapeUtils" class="org.apache.commons.lang.StringEscapeUtils" scope="application" />
<script>
var accountNumber = '<c:out value="${ACCOUNT_NUMBER}" />';
var accountNumberWithSingleQuote = "<%=StringEscapeUtils.escapeJavascriptString('<%=accountNumber%>')%>"; // not working
alert(accountNumberWithSingleQuote );
</script>
Here var accountNumberWithSingleQuote = "<%=StringEscapeUtils.escapeJavascriptString('<%=accountNumber%>')%>"; // not working
Here how to add the parameter accountNumber in the escapeJavascriptString() method?
Is it possible can we do it without scriptlet in JS? Pls. let me know your opinion.
thanks.

Here var accountNumberWithSingleQuote = "<%=StringEscapeUtils.escapeJavascriptString('<%=accountNumber%>')%>"; // not working
The above line will not work, because you are using scriptlet within a scriptlet.
accountNumber is a javascript variable, so there is no way to use javascript variable in scriptlets.
Here how to add the parameter accountNumber in the escapeJavascriptString() method?
Is it possible can we do it without scriptlet in JS? Pls. let me know your opinion.
You are assigning a value to accountNumber variable using springs variable, i.e ACCOUNT_NUMBER.
So why don't you directly use the ACCOUNT_NUMBER variable which is a java scriptlet.
Below is the url will guide you for the same:

My Page1.class file is as follows
* Page1.java
package a1;
import ....
public class Page1 extends AbstractPageBean {
    public void valset(int val) {
}my jsp file "Page1.jsp" is as follows:

Call applet methods from Javascript

Hello,
If I call applet method like :
function callbackFunc(){
var pp = appletID.getData();
alert(pp);
It works only if applet is deployed with <APPLET> tag or with javascript.
If applet is deployed using <Object> and <embed> tags, in browser console the error is :
TypeError: appletID.getData is not a function
I couldn't find why is that behaviour. What do I do wrong?
Thanks

Hi Paul,
(1)Seems to be your Java Runtime Environment path is still setted for JRE 1.3.0_01 and not for 1.3.1. So pelase go to the
Control Panel-->java plugin 1.3.1-->Advanced. Here you set the Java Runtime Environment to the JRE 1.3.1 version. Its better to remove the older version before installing the new version on JRE.
(2)<OBJECT> tag won't work for Netscape. You can only use <APPLET> or <EMBED> tag for Netscape.
Hope this will help you.
