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 javascript function & action method on clicking jsf button?

I have one jsf custom button. I am checking client side validations in mail by calling javascript function & also sending mail by calling action method of a bean which will execute at server side for onclick event of that button. Because of this when I click on that button its calling both javascript function and action method. So even though validations failed its sending mail. How can I overcome this problem?? Please help me....

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!

The JSP has the textbox as given below.

Using this I could not acheive the required functionality. Please suggest some alternative.

Only a form element supports the submit() function. Make sure that the getElementById returns the appropriate form. Or rather pass the element as the 'this' reference to the function and get the parent form from it.
After all this is just basic DHTML / Javascript+DOM knowledge and in fact this has nothing to do with JSF. For future basic DHTML / JS+DOM questions you may take a look at the appropriate forums, e.g. dhtmlcentral.com, dynamicdrive.com, etcetera.

How to call javascript function when form load[like onload="fun()" in html]

I have to call javascript function at the time of iview is loading. I am not able use onload event which is not working in SAP Portal environment. Please suggest me any other alternative to call the function at the time of iview is loading. I have to set some properties when form is loading.

I will explain my scenario correctly
Let us take two pages
1. Main Page (A)
2. Child page (B)
       I have displayed records in tableview and each having checkbox and two buttons "print" and "viewDetails" at down in page A. If I clicked "print" button the records which i have selected checkboxes details will be displayed in new window( page B). In page B i have given this following code
<script language="javascript">
      window.opener.setTarget('Search');
</script>
setTarget() function is in page A.
function setTarget(opt) {
if(opt=='print')
     opt="";
     document.<%=strFormControl%>.target="_blank";
   else
        document.<%=strFormControl%>.target="_self";
This code is executing after the content of all records details displayed.
My condition is If i click print button new window is opened and details are displaying. And before displaying content in new page B (means after opened new window) if i click on "viewDetails" button that is also opening new window because <script> code is not executed not yet. but it should display in same window when i click "viewDetails" button.

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.

Reason is: I dont want to place button on the form to perform any action on the form. I want to take control of the form from these buttons. Like submit, edit a form, etc, etc..
Please let me know if i couldnt explain it properly.

Sunil, you want to look at the "Customizing the LiveCycle® Workspace ES User Interface" document at http://help.adobe.com/en_US/livecycle/9.0/customizeworkspaceui.pdf. The workspace is a Flash component. For ES4 there's an option to run the workspace in HTML5 which might be more productive long-term.

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 invoke javascript function after business action??

How to call javascript function(such as "window.close(), window.open(...),...") in the action method(public String doBusiness(){...}) of <h:commandButton>?If not,then,is there any alternate approach to call javascript function when the bussiness action method finished??
Thanks a lot!

Since your business method is called after the form is submitted, and your code is running on the server, probably the only thing you can do is this:
Create a custom component (Maybe call it the "onLoad" component) that you always render at the top of your JSP. In the regular situation it wouldn't render anything, but in the case you mention, after your busines method, you would call a method on this new component on the server that would cause it to actually render something the next time it is rendered. When rendered this time, it could then render the "onLoad" method which has your window.close() code in it. The window would then close right away.
The key is that you are not doing any of this on the client. The form is submitted, your business logic is executed, then the next page is rendered. When the next page is rendered, your javascript could be rendered to close the window.
If I'm offbase here, someone please say something, I'd hate to send this guy on a wild goose chase.
