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.

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!

Can we call a javascript fun through jsp page without any event

Hi ,
I am new to jsp,javascript and i have a little question.
If i make a function in a js file and want to call it from a jsp file without any event ,ie can i write some thing like <%abc()%> in ths jsp page ,which call the function from another .js file.
I suppose that it can be done as gmail page reloads it self after some time and for http mostly we use pull ie request from the client side ,so i think that they must be doing something like timer expiry and reload themselves.
please help me with the solution.
Thanks & Regards
Saurabh

sorta....
The JS runs in the client, not on the server, so you would just be writing JS code as HTML... If your page is like this and the myscript.js file defines 2 functions (function1, function2), you can call them on page load in either of these ways. I'm not sure offhand which would get called first, but the scripts called inline in the page would be called in the order they are defined in the page. But that is all HTML, it has nothing to do with JSP.
<head>
<script language="JavaScript" type="text/javascript" src="myscript.js" />
</head>
<body onload="function1();">
<script language="JavaScript" type="text/javascript">
function2();
</script>
</body>

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.

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.

How to call a SQL function from an XSL expression

Hi
In R12, in Payroll Deposit adivce/Check writer, We need to sort the earnings tag <AC_Earnings> in to two different categories as regular and other earnings. In the DB and form level of element defintiion we have a DFF which differentiates between the two kinds of earnings. But the seeded XML that is gerneated by the check writer does not have this field.
The seeded template displays all the earnings in one column. How can we achieve this in the template without modifying the seeded XML.
The one approach i have is to write a function and based on the return value sort the data. For this I need to know :

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.

Call javascript you use the JSObject
Please note the MAYSCRIPT int the html file.
html file:
     <object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
              height="0" width="0" >

                height="0" width="0"

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,
Ruby

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.

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

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.
