Calling JavaScript functions from Java

Hi,
I am trying to call the javascript function alert("text message") from a section of Java code.
I want to do something like below....
if (balh blah blah...){
isFound = false;
alert("Record already exists");
Dose anyone know how to do this?

If your Java code is in a JSP page or a Servlet, then yes, but not exactly...
Since the Java portion of a JSP / Servlet is executed on the server side, there is no way to instantaneously pop up something to the user per se - the code is executed on the server before the output is transmitted to the browser.
What you could do, however, is to have a JavaScript function defined in your page which would perform the alert:
<script language="JavaScript">
function userAlert(message){
    alert(message);
</script>Then, on the jsp/servlet side, you could perform your if/else check:
String bodyTag = "<body>";
String userMessage = null;
if (balh blah blah...){
   isFound = false;
   userMessage = "Record already exists";
   bodyTage = "<body onLoad=\"userAlert('" + userMessage + "')>\"";
}This way, as soon as the browser loads the page, it alerts the user with your message.
Hope this helped,
-Scott

  • Call DLL function from JAVA

  • Calling c function from java!!

    hi all,
    I want to call c function from java . I have gone through the link http://java.sun.com/docs/books/tutorial/native1.1/stepbystep/index.html for JNI.
    According to this link we need to write the native method implementation in such a way that the method signature should exactly match the method signature created in the header file.
    My problem is that i have a c application which i cannot modify in any ways i.e., i cannot change its code. But i want to call its function from my java code.
    Please suggest me appropriate solution for this. Please let me know whether it can be done using JNI or is there any other method for this.
    thanks

    This link is amazing since those sources were wrote in 1998 and I started to develop JNative in 2004. I did not found them when I started.
    Since JNative can deal with callbacks and probably COM in a near future, I expect to see it living to Dolphin at least.

  • 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 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'">

    <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.

  • 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 javascript function from report customization form

    I have been unable to call any user-defined javascript function from Portal Report Customization forms.
