Work In Progress: This page is under development.

__TBD: ___

• Make a multi-page help system
• make two JSP pages ()
  JSP_Pages#About_Header_Files
• make the main page into the help tab
• How to open a different window from a help button, rather than a link

About Application-Specific Help

The information here in the support wiki is intended primarily for application builders, admins, and installers. But end-users need information that is specific to the application they are using--and that is where application-specific help comes in.

In this article, we assume that you know how to add a button to a form, and that you know how to create an interface tab that displays a single HTML page of information. (The important point is to make sure that your help pages have no headers, so that links work.) With those basics in hand, you can go on to create context-sensitive help pages for your application.

Working with Application-Specific Help

Here, we assume that you want to display different pages, depending on the user's current location--so you'll be wiring help buttons that appear on different forms so they display different pages in the help tab. (You may even use JavaScript to go to different help pages, under different conditions.)

To Go to the Help Tab

• --get the ID of the Web Tab, or inspect the tab element to get iFrame ID
• --Find the Help tab and use {element}.click to click the tab!

<script>
function goToHelpTab() {
   document.getElementById("...HELP TAB ID...").click();
}
</script>

To Load a Specific Page Into the Help Tab

From a button:

<script>
function go(loc) {
   var helpTab = document.getElementById('...HELP TAB ID...')
   helpTab.src = loc; // Where the loc is any URL on the web
   helpTab.click;
}
</script>

--__TBD: Show relative URL to get to a JSP page__

From a link in a displayed page:
__TBD: does a relative link "just work"?__

• --To display link-target in the Help tab:

function to search for the iFrame and change the src attribute:

onclick() in the anchor to invoke the function and pass target

--loc.href="pages/PAGE_NAME"

--works for pages hosted in the platform

--does not work for external pages (use the external site option, for that)
