How to Warn The Users If They Try To Close The Browser When A Forms Session Is Running

There is some code (javascript) that can be used to add a warning for the users if they try to close the browser when a forms session is running and they can lose the unsaved changes.

For this you have to do some simple steps:

  1. Go to $ORACLE_HOME/forms/server
  2. Edit your HTM file used (basejini.htm) or create a customer one.
  3. Add a javascript code like explained bellow after the BODY tag.
    Replace this code:

    <BODY %HTMLbodyAttrs%>


    a. This code:

    <BODY %HTMLbodyAttrs%> 
    <script language="JavaScript"> 
    function confirm() { 
    event.returnValue = "Closing Oracle Forms Application. Any unsaved changes will be lost! OK to Continue with close ?"; 
    Note:  This code is working only on Internet Explorer browser.


    b. This code:

    <BODY %HTMLbodyAttrs%>  
    <script language ="JavaScript1.2" type="text/javascript"> 
    isSolved = false; 
    function unloadMess(){ 
        mess = "Closing Oracle Forms Application. Any unsaved changes will be lost! OK to Continue with close ?"
        if(!isSolved) return mess; 

    Note: This code is working with Internet Explorer, Netscape and Mozilla Firefox browsers.

  4. After that save the file and start a new session.
