Accessing JavaScript function from an Applet?

Hi,
I've found how to access an applet's method from Jscript, but can we do the inverse? I'd like to refresh some frames in my web pages from my applet.
The refresh of several frames could be done with a Jscript function but how can I call it from my applet?
Thanks!

Calling a javascript function from an Applet

I am trying to make an applet that works on as many browsers as possible, so I am sticking to Version JCK 1.1
I am trying to call pass the javascript function into a URL object like this
URL url = new URL("javascript:" + function, "_self");but I keep getting a MalformedURLException. I've read some of the other comments, but they all say to use the netscape.javascript package and the JSObject class, but I can't find that object anywhere inside the API posted on Sun's website.
Any help would be greatly appreciated.

To access JavaScript methods, properties, and data structures from your Java applet, import the Netscape javascript package:
import netscape.javascript.*
public class myApplet extends Applet
{ public void init()
{ /* Use the following syntax to call JavaScript methods:*/
JSObject.getWindow().eval("expression")
/*expression is a JavaScript expression that evaluates to a JavaScript method call. */ }

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:

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!

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,

WHY can't I access my database from an applet???????????

The security code won't let my applet access its own database (from its own server)..
I'm using getDocumentBase()
to try and tell it that it is my own damn file..
I keep getting :
java.securityAccessControlException: access denied <java.util.PropertyPermission jdbc.drivers write>
...etc.
This applet crap is really starting to piss me off. I can see why they came out with JSP.
All I need to do is access my database, update it, etc. It kind of defeats the purpose of being able to do jdbc from applets if you can't even access the database on your own damn server.
If you all don't have a clue, I'm freakin switching to PHP--I'm tired of this crap-I was thinking Java was a damn good language until I hit applets.

The simple answer to your question is: Because of security concerns.
The somewhat longer answer is that directly accessing a database from an applet is generally not a good idea. A lot of security-critical code like DB username/password must be hidden in the applet which potentially can be downloaded (and disassembled) by anyone that hits your webpage. Maybe you do an intranet solution with trusted users but that is not what applets were originally designed for.
The clean way is to make your applet talk to a servlet that talks to your database.
If that is not the way you want to do it, make sure that all client policy files (yes, on the browser machine) contain the permissions that your applet needs.

Calling javascript functions from xsl on mac safari

Hi,
I am having a problem calling external javascript functions from xsl on mac safari, i am trying to generate a dropdown dynamically from an xsl document using XSLTProcessor through javascript, following is the code snippet of the xsl document
<select name="ddl_EmailSubType" class="Menu" onclick="onEmailSubTypeChange();" id="ddl_EmailSubType" >
<xsl:for-each select="./SubTypeFields/FieldGroup">
<xsl:if test="@SubTypeGroup != 'All'">
<option>
<xsl:attribute name="value">
<xsl:value-of select="@SubTypeGroup"/>
</xsl:attribute>
<xsl:if test="@SubTypeGroup = $SelectedSubContentType">
<xsl:attribute name="selected">selected</xsl:attribute>
</xsl:if>
<xsl:value-of select="@SubTypeGroup"/>
</option>
</xsl:if>
</xsl:for-each>
</select>
here the function onEmailSubTypeChange() is present in an external js file, all the other functions from this files are executed successfully except the ones which are defined in the xsl document.
I have also tried replacing onclick="onEmailSubTypeChange();" with onclick="javascript:alert('hello world');" but the event is not getting fired at all since i cannot see any alert on the selected item change of the dropdown.
Is there a way in which i can achieve this ?
any helps appreciated.
Thanks in advance

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.

Call javascript functions from PL/SQL

Hi !
I just want to know if it is possible to call a javascript function from a PL/SQL procedure. If yes, anybody can explain me the syntax ?
Thanks
Chantale

You can call Java Script - kind of.
PL/SQL has a "web browser" called UTL_HTTP. It allows you to make HTTP calls to a web server. This includes a function that can be used from SQL too (with a size limitation).
Example:
SQL> select UTL_HTTP.Request( 'http://some-web-server' ) as HTML_PAGE from dual;
HTML_PAGE
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<META HTTP-EQUIV="Refresh" CONTENT="1;URL=http:/some-web-server:7777/index">
<html xmlns="http://www.w3.org/1999/xhtml">
<img src="images/Wave.gif">
Redirecting.. please standby..
<hr>
</html>
SQL>The call to the web browser can be to execute and load, for example, a JSP page.
However, if the page containts client-side Java script, i.e. code for the web browser to execute, than UTL_HTTP will merely return the contents & code of that page.
Client-side Java Script requires an engine in the browser. The JS language is used to manipulate the rendering engine of the browser.
The PL/SQL "web browser" does not have a display device to show a web page. Thus it is without a web browser rendering engine and therefore also cannot execute Java Script either.

Calling javascript function from report customization form

I have been unable to call any user-defined javascript function from Portal Report Customization forms.
Even a simple Message Box function doesn't work. I've been placing my code in the ..after header PL/SQL section for the report customization form.
htp.p('<script type="javascript">');
htp.p('function MsgBox(message){');
htp.p('alert(message);}');
htp.p('</script>');
htp.p('See if it works');
I have verified in plain html that my syntax is fine. Even the syntax rendered by portal is correct:
<script type="javascript">
function MsgBox(message){
alert(message);}
</script>
See if it works
Despite this, you will get a javascript error that an Object is expected, MsgBox not defined. Clearly from the script above MsgBox is defined.
I have tried any number of calls to user defined functions and can't get anything to work. However, calling native functions like 'alert' works fine ( ie
See if it works
Anyone know how I can call a user defined javascript function in a Portal Report Customization form?

Try changing the code
htp.p('<script type="javascript">');
to
htp.p('<script language="javascript">');
Thanks
