281210 - form action is not relative to specified base

Status: RESOLVED DUPLICATE of bug 280470

(Firefox :: General, defect)

Description

[Baron Schwartz]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

The "action" attribute of the form is not resolved relative to the base url
specified for the page, when present.  Instead it is considered relative to the
current page.

Reproducible: Always

Steps to Reproduce:
1. Load the test case I will attach
2. Right-click and view page info, then the Forms tab
3. Notice that the form's action is not relative to http://www.mozilla.org.

Actual Results:  
The form's action is relative to the file's current location.  In this case
since it's on my hard drive, that is file:///relative-to-mozilla-dot-org instead
of http://www.mozilla.org/relative-to-mozilla-dot-org.

Expected Results:  
The form's action should have been
http://www.mozilla.org/relative-to-mozilla-dot-org as specified by
http://www.w3.org/TR/html4/struct/links.html#edef-BASE

Page Info doesn't resolve the URI, see the testcase linked above to see this in
action.

[Phil Ringnalda (:philor)]

Well, yeahbut: that's Page Info displaying a bug in our DOM, which reflects a
bug in the DOM 2 HTML spec. (I should have looked farther before titling bug
280470, but the patch covers form.action as well as image inputs.)

Yep.  See
http://lxr.mozilla.org/seamonkey/source/content/html/content/src/nsHTMLFormElement.cpp#1322
for where forms compute their action URI when they submit.
