I've created an xxx_yy_edit PT so that my AT type will automatically look to
process from this page first.
In my xxx_yy_edit page I have only the following:
In other words, I only want to override "extra_top" from edit_macros.
In my "extra_top", I want to add <form> sub-elements such as <select>.
Based on the changing of the <select> value (onchange), I want to submit()
the form. I presume that the form is named "edit_form" (from edit_macros)
and there's only one, so I have code something like:
onchange="submitPage(); return false;"
var edit_form = document.forms['edit_form'];
In IE, get the error: "Object doesn't support this property or method" on
the submit() line. In FireFox I get something similar.
I've looked into the "edit_form" class attribute
(class="enableUnloadProtection"), but am unsure of exactly what it does, but
get the feeling it's my problem.
I've thought about re-setting the "class" attribute of edit_form.
I don't want to provide a "submit" button. However, when I have during
testing, the I do not return to the xxx_yy_edit page, but the view page
(with the message "Changes Saved.".
Also I *do* want to create a round-trip to the server with the "onchange"
since there's a lot of method calling done by <tal> on the re-load. If I
had to put my logic in JS, it'd be possible, but ugly.
Also possible is overriding the whole "body" macro in edit_macros, but
that's not elegant either (too big of a hammer).
Can someone explain what is happening here, and if they've come up with a
