APEX JavaScript Directory Hierarchy on the HTTP Server Oracle Tips by Burleson Consulting

JavaScript in the Directory Hierarchy on the HTTP Server

Putting the JavaScript source code in the script repository makes it reusable and it is easy to deploy in this manner, but we can still do better.  This next step is better because it allows the users web browser to cache the easy_java.js script locally.  That way the next time the same script is referenced it does not need to be downloaded to the users’ browser since it was downloaded previously.

SEE CODE DEPOT FOR FULL SCRIPTS

The following explanation assumes you have access to the place files in the directory structure of the machine where the HTTP Server is running.  I also assume your images directory is the same as the path shown here:

Windows:

C:\oracle\product\10.2.0\ohs\Apache\Apache\images

Unix/Linux:

/u01/app/oracle/product/10.2.0/ohs/Apache/Apache/images

What you need to do at this point is create a new directory named easy_htmldb under the images directory.

C:\oracle\product\10.2.0\ohs\Apache\Apache\images\easy_htmldb

Then copy the easy_java.js script from the code depot directory to new easy_htmldb directory.  This places the file in the correct location for us to reference it from each of the application pages.  It also makes it available to all applications in all workspaces running from this HTTP Server.

To change the refenence in the HTML Header region of the Java Script page navigate back to the page attributes page and make the changes as shown in figure X.5.

The changes in figure X.5 involve the substitution string and a reference to the new easy_htmldb directory (shown in bold below).

<script src="#IMAGE_PREFIX#easy_htmldb/easy_java.js"

type="text/javascript"></script>
