If you take a look at http://jsfiddle.net/kborchers/Amf5x/3/, you'll see that when you fill out the form, the array that is logged contains the submit button but the exact same code here without jQuery Mobile http://jsfiddle.net/kborchers/Amf5x/4/ does not include the submit button. I would imagine that the submit button should not be there which is why I am filing the issue here and not in core. Also, the same issue exists here http://jsfiddle.net/kborchers/Amf5x/5/ with latest jQM and jQ1.7.1.
This is due to the buttonPlaceholder that gets injected in jquery.mobile.forms.button.js
@kborchers Looking at the JQM code this seems intentional if the submit button has a name attribute. See ecc1361
Maybe @Wilto could shed light onto why we do this.
Yep, that's the case. People often use submit buttons with different name/values so we made sure they're serialized along with the rest of the form. Maybe core needs to do the same.. I'm not sure why it doesn't include submit buttons by default.
@scottjehl should we close this issue?
this is fixed in latest http://jsfiddle.net/Amf5x/7/
