I am working on a small web page that uses Javascript in Firefox 2.0 to
make SOAP calls. The page is loaded from the local machine as a file
(file:///C:/...., no web server used), and the SOAP server process is
running on the local machine (http://localhost:7090). I can make my
SOAP call with its single parameter ( Create-EVNT(xml) ) without any
problems, and I receive the return value (a single string) without any
problems as well.
The issue I'm having is that when I make the same, identical SOAP call
a second time, by clicking my HTML form button again, I get the
following Javascript error in the console:
uncaught exception: Security Error: Content at file:/// may not load
data from http://localhost:7090.
However, the THIRD time I try to make the SOAP call, I am able to
without any issues. So essentially, every other SOAP call gets the
error stated above. Also, when I try to reload the page before the 2nd
SOAP call, I get the following error:
parse_event_data is not defined
This is very strange, since the Javascript function IS available. It's
like the page is in a funky state or something. If I reload the page
yet again, the SOAP call goes back to working every other time.
I have been unsuccessful in finding the root cause of the problem, and
was wondering what insight the community had. I'm including both the
Javascript file (create_event.js) and the HTML file (create_event.html)
at the bottom of this post.
Thanks in advance!!
