IMPORTANT: IF THIS SCRIPT IS CUSTOMIZED FOR A CLIENT, BE SURE TO
PROTECT IT IN THE FORM TOOL.
Description: JavaScript code for a client to include in their web
site page(s) that host an iframe that loads a page
served at thedatabank. At this writing, the client's
iframe may be hosting Online Forms and/or an Advocacy
site.
thedatabank's software setup records the URL of the
client's iframe hosting page(s). When the tdb software
needs to link to an Online Form or Advocacy page, it
creates a URL to the client's hosting page, passing the
tdb URL in the querystring. tdb software cannot link
directly to the Online Form or Advocacy page, because
it would be unbranded - the client's hosting page
provides the branding. By passing the URL to load into
the iframe, and letting this script figure out what to
load into the iframe, the client does not need to have
a hosting page for every page that thedatabank's software
might need to link to, AND does not need to do any
programming. They simply need to add the following to
the section of their hosting page(s):
FOR ONLINE FORMS (secure):
FOR ADVOCACY (not secure):
Setup: If the client has Advocacy, set their domain in the
stdbHostedActionDomain variable.
This script adds window.onload code. For sites that use
JQuery (or other JS frameworks), there's potential to
conflict with the JQuery .ready event, or similar
functionality on other frameworks. The site may also
have its own window.onload code for its own purposes.
The AddLoadEvent function is attempts to avoid these
conflicts. In testing this script seemed able to
peacefully coexist with JQuery, but still, it might need
to be tweaked in to work on some sites.
