Can we call a javascript function from backing bean class?

I have a requirement. In a multiselect table, when users selects some rows and clicks a button. Depending upon some condition, an alert box should appear with 2 buttons 'Yes' and 'No'. On clicking yes, certain field values in the selected rows of table should change. On clicking no, the alert box should close. As far as i know alert box can be done only in JS.
Please help me, if a javascript function can be called in backing bean method or suggest some way where alert boxes can appear through ADF.

I need to go back to the backing bean as i need to iterate through each selected row of the table in a method( method written for command button) and then if atleast one of the selected rows has job field='Manager', then an alert box needs to be displayed. If none of the rows have job field as 'manager', alert box should not be displayed.
If I write the function for onclick, i cannot iterate through the selected rows of the table in JS function.
Please suggest a way to do this.

Hi,
to call the bean, use the EL in Java and reference #{backingBeanScope.mapBean.initMap} as a method expression. If you try and access the bean directly then chances are that the instance is not available. Using EL from Java always guarantees this

ADF Question: call javascript function from backing bean?

Hi all,
I am running JDeveloper 10.1.3.3 with ADF BC.
Heres my situation:
I have a table, and after inserting a new row, then committing, I want to call a javascript function. I tried using the onkeyup javascript to force a click of the save button, and then call my function after that. However, I really only want the second function to be called AFTER the commit has occurred.
I have tried putting a setTimeout on the second function, but this never executes then. Is there some way that I can call the second javascript function from the backing bean? Is there a better workaround for this? Here is some code:
        function submitCreate(e) {
            var _event = (window.event) ? event : e;
            var KeyID = _event.keyCode;
            switch (KeyID)
                case 13:
                    document.getElementById("form1:tvoTable:commitButton").onclick();
                    doAjax();
                    break;
        function doAjax() {
            var item = document.getElementById("form1:inputText3").innerHTML;
            getAjax(item, "FULL");
        }Thanks,
Heather

Maybe try adding an af:script block in your jsp as a partial target in your backing bean when you commit to the database? We are doing something similar when we get a tab DisclosureEvent but the principle should be the same.
In our jsp we have:
<af:script id="scriptID" text="alert('javascript here');"/>
In the backing bean we have:
method(DisclosureEvent de) {
// get a component somehow or the component, we get it from the disclosure event
// but you could use a binding also. if you don't have the exact script element you need
// to find it like we do below.
UIComponent c = de.getComponent();
// Find our real script component
UIComponent target = c.findComponent(":scriptID");
// get the adf context
AdfFacesContext adfContext = AdfFacesContext.getCurrentInstance();
// add the script as a partial target.
if(target != null) {
adfContext.addPartialTarget(target);
This relies on PPR though, which you may not be doing. If you are navigating to a new page you could set an indication in a backing bean and then access that in an <af:script> block in the new page or even generate the Javascript you want depending on your logic and access all of it via an EL binding on the af:script tag:
<af:script id="scriptID" text="#{bbean.generatedScript}"/>
Hope this helps!

Calling function from Backing Bean or JSP page

We are on Jdeveloper 10.1.3.3.0, ADF Faces, JSF Faces .., Currently there is a function call from Javascript event (onmouseover) in the JSP page. I want to call this function from a backing bean or JSP page, as I have to pass some values to this function.
For Ex., I have a function call like return submit('A','B','Test'); on the Javascript event (onmouseover) in jsp page. I want to remove this function from the javascript event and call from backing bean or jsp page to pass some values into the submit() function. I appreciate if anyone can give some example of how to call this function from backing bean or jsp page in the <SCRIPT> or <SCRIPTLET>
Thanks,
Ram

A use case would be helpful so that we can get a better idea of what you want to do.
As a general rule, there is no way to call a client side Javascript function from a backing bean, which is server side. However, there are ways to inject information from a backing bean into your Javascript call. For instance, I have an application that uses Google Maps API. It has an onload call to a Javascript function that builds the map and designates it's center point. The center point comes from a backing bean as latitude and longitude properties. So here is my body tag:
<afh:body onload="initialize(#{backing_searchResults.latitude},#{backing_searchResults.longitude},#{searchCriteria.distance})"
onunload="GUnload()">onload calls the Javascript function called initialize, and passes the latitude, longitude, and distance from the bean. Is the function really being called from my backing bean? No - the parameters are hard coded into the onload event code when the page is rendered. Does it do the job? Sure it does.

Calling a JavaScript function from an JApplet...

Can anyone help? Is it possible to call a JavaScript function from within a JApplet? If so, what is the syntax? I've seen reference to the Netscape package but I've been led to believe it doesn't always work within Internet Explorer 6 which is the target browser.
If the above is not possible can anyone tell me if and how it is possible to load images from outside the init() method of a JApplet? This would allow me to work around the problem.
Thanks in advance - Jim.

Is it possible to call a JavaScript function from a dialog?

Hi there,
At the moment I have created a dialog, that consists of three text fields that a user fills out, and then clicks next.
What I am attempting to do, is pass the result of these three textboxes to a JavaScript function I have laying in a file in Web Resources. I've done some research, and I can't find anything.
So my question is - is it possible to call a JavaScript function from a dialog?
Thanks for your time.

Hi,
It is not possible unfortunately. We can start dialog from script but not the other way unfortunately. However, you can always write server side code for this and it will surely execute. So instead of javascript, write plug-in.
Hope this helps.

Help needed in calling a javascript function from a jsp

Hey guys,
I need help.
In my jsp I have a field called date. When i get date field from the database, it is a concatination of date and time field, so I wrote a small javascript function to strip just the date part from this date and time value.
The javascript function is
function formatDate(fieldName)
          var timer=fieldName;
          timer = timer.substring(5,7)+"/"+timer.substring(8,10)+"/"+timer.substring(0,4);
          return timer;
Now I want to call this javascript function from the input tag in jsp where I am displaying the value of date. Check below
This is one way I tried to do:
<input size="13" name="startDate" maxLength="255" value=<script>formatDate("<%=startDate%>")</script> onChange="checkDate(this)">
I even tried this:
<input size="13" name="startDate" maxLength="255" value="'formatDate(<%=startDate%>)'" onChange="checkDate(this)">
But it dosen't work
Please help. I am struggling on this for days.
Thanks,

How to call javascript function in back bean of jsf

hi,
i am trying to call java script function in back bean but not done. Is there any code for call javascript function in bean file.

Java runs at server side.
JSF produces HTML output.
Server sends HTML output to client.
Java stops running.
HTML runs at client side.
JS starts to run in HTML.
Clear? Java is a server side language. JS is a client side language. To run JS using JSF, simply print it out to the HTML so that it get invoked when the HTML runs.

How to call a javascript function from XSL

I'd a requirement to take an action each time a page loads
I called the javascript function from addLoadEvent() available in javascript.
But my reviewer commented that it should be called using XSL as we are using XSLT,
What is preferred?
To pass function name to the already available function or somehow call it from xsl ? if second is preferred option then,
how to call a function through XSLT, if it is to be called aftr the page loads?

Thank u..
but i'd seen that link wen i searched in google..
Is it possible without using any 3rd party JARs and all?
and more importantly plz tell me what should be preferred way to call a javascript function?
Do it using addLoadEvent() or Windows.Load etc
OR
Call it thru Xsl? (I donno how to do dis)

Can we call a task-flow from a bean in adf?

Sir,
Can we call a task-flow from a bean in adf?

you can do this using taskflow call activity
check - Oracle ADF World: ADF Task Flow Call Activities
http://docs.oracle.com/cd/E24382_01/web.1112/e16182/taskflows_activities.htm#ADFFD21945
you can pass input parameter map and dynamic taskflow reference from managed bean
check -https://blogs.oracle.com/DavidGiammona/entry/dynamically_assign_task_flow_c
Or if you want to use dynamic region to swich between taskflows

Few basic doubts about accessing AM from backing bean class

Hi ADF experts,
I have just started working in ADF Faces.I made a sample search page.My page is attached to a managed backing bean. I have attached command button on my page to a custom method in backing bean class.
So on, click of button this method is called in backing bean.Now, i have few doubts:
1)How to get values of various UI beans in this event code?
2)I am accesing AM , in my method with this code:
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext extContext = facesContext.getExternalContext();
Application app = facesContext.getApplication();
DCBindingContainer binding = (DCBindingContainer)app.getVariableResolver().resolveVariable(facesContext, "bindings");
//Accessing AM
ApplicationModule am = binding.getDataControl().getApplicationModule();
iS this correct ?
3) After getting handle of am how to call my custom method in AM Class?there was "invokeMethod" API in application module class in OAF, is there any such method here?
Please help me.
--ADF learner.

Thanks for ur response Frank, actually I am from OA Framework back ground.It would be great if help us a little with ur valuble thoughts.
OA Framework also uses bc4j in model layer of framework. We have a requirement where our existing developers from OA Framework have to move to ADF to make a new application where time lines are quite strict.If this would not be possible we will switch to plain jsp and jdbc,but our tech experts say ADF Faces is the best tech.
In OA Framework, Application Module is key class for all busiess logic and Controller is used for page navigation. So, I m just trying to find the same similarity , where we write we add all event codes in custom action methods in the backing bean class of page, which we consider equivalent to process form request method in Controller class of OAF.
But there are two things, I still want to know:
1)While page render, how to call specific AM methods(like setting where clause of certain VOs)
2)In action methods, the way i described(I found that in one thread only)to access AM, what is wrong in that?Also, I went through
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
where coule of examples use similar approach to access AM from backing bean class and call custom methods of AM(Doing various, deletes etc from VOs).
3)In these methods can we set any property of beans on the page, I am asking because in OAF, generally we use PPR for js alternatives.But all properties of beans cannot be set in post event.
Thanks and Regards

Can i cal a javascript function from a jsp without occurance of any event??

Hi,
Below is the problem that i am facing:
Problem:
I want to open a new url from a java class.
I have a java class. I am calling a jsp from this java class. JSP does some validations and after these validations, opens a url in new window. But I want to append some runtime parameters in the url and pass it through post method in jsp so that end user cannot see these parameters. Can any one tell me how to code for this schenario?
Class A calls X.jsp
X.jsp
1. do some validations
2. call some javascript function
3. append the parameters in the url using dopost method
One more thing to mention, when calling this jsp, i need to show this jsp to user, therefore there would not be any event in this jsp. I need soluions for following points:
1. Without occurance of any event, my javascript function must be called
2. desired parameters must be appended in the url
3. New url should be opened and the parameters should not be visible to end user.(ie parameters need to be passed via post method in jsp)
Appreciate your help.
Thanks,
Rajeev

You are all mixed up. Here's how it works: a JSP is a program that executes on your server. It generates HTML (which may include Javascript) and sends that to the client, most likely a browser. When it has finished generating and sending all that HTML, the browser accepts it and renders it. The browser may execute Javascript as it renders the HTML, or it may execute Javascript later upon a click or mouse action or whatever.
So your idea that the JSP will execute some Javascript is a non-starter. And that business about the JSP appending parameters and using the POST method is all backwards, unless perhaps you meant that the JSP would generate HTML containing a form that does that.
Anyway you need to clarify your thought based on how things actually work. Confounding the two phases (generating HTML on the server, rendering it on the client) will make it very difficult for you to get anywhere.

How do you call a JavaScript function from a Java applet

I have an Applet that needs to run on the following platforms: Internet Explorer (Windows-NT, Windows -2000), Netscape (Windows-NT, Windows-2000, Sun(Solaris), RedHat(Linux), HP(11.0), IBM(AIX)).
The Applet needs to call a JavaScript function that is included on the HTML page that contains the applet. In JRE-1.3.1 I used the AppletContext.showDocument(url,"_self" ) where the url is "javascript:MyScript('param1')". This works just fine. I tried using showDocument without the second parameter and all the other choices for the second parameter and none of them worked (nothing happened).
I tried the same code with JRE version 1.4-beta. It seems that version 1.4-beta no longer supports a URL that starts with "javascript" in the AppletContext.showDocument(url,"_self" ) method. The error is:
netscape.javascript.JSException: call does not support self.open
at sun.plugin.javascript.navig.Window.call(Unknown Source)
at sun.plugin.ActivatorAppletContext.showDocument(Unknown Source)
I tried to catch the JSException but I cannot seem to.
I then tried a completely different approach. I then grabbed the JSObject for the page and tried to call my javascript function (MyScript) directly:
JSObject theObj = JSObject.getWindow(this);
Object paramArray[] = new Object[1];
paramArray[0] = Param1;
theObj.call("MyScript", paramArray);
This worked fine on Netscape[Windows-NT, Windows-2000]. HP throws a JSException on getWindow() and Solaris just hangs. I did not even try IE.
What is the recommended approach here?

you can try this, it worked for me:
JSObject win = JSObject.getWindow(this);
win.eval(function_call);
I have other ways also, so if this doesn't work, let me know.
