I'm having an issue that is driving me crazy. I'm trying
to modify the openid-selector
to support facebook. I'm using RPXNow as my provider so it requires the form
to be submitted
to a different url than the standard.
For example. RpxNow requires me
to setup my form like this:
<form action="https://wikipediamaze.rpxnow.com/openid/start?token_url=...">
This works for every provider except for facebook and myspace. Those require the form
to be posted
to a different url like this:
<form action="https://wikipediamaze.rpxnow.com/facebook/start?token_url=...">
and
<form action="https://wikipediamaze.rpxnow.com/myspace/start?token_url=...">
The open id selector has a bunch of buttons on the form each representing the openid providers. What I'm trying
to do is detect when the facebook or myspace button is clicked and changed the action on the form before submitting. However it's not working. Here is my code.
I've tried several variations all with the same "not supported" exception
$("#openid_form").attr("action", form_url)
document.forms[0].action = form_url
Any suggestions?
Update
Here are more details on the code. I've ommitted some for brevity. The only thing i've done is added the facebook section
to the "providers_large" object (which successfully adds the logo
to the website), and instead of supply a url identifying the user, I'm creating a property called "form_url" which is what I want
to set the action of my form
to. If you look at the section title "Provider image click" you'll see where I'm checking for the presence of the property "form_url" and using jquery
to change the action and submit the form. However when I step through the javascript in debug mode it tells me it's an ivalid operation.
