(Core :: DOM: Core & HTML, defect)

Description

[Fredrik Ohrstrom]

A javascript that changes the value and name of a hidden field in a form
and then posts the form behaves incorrectly under Mozilla.
Mozilla changes the value of the wrong field.

Please look at the webpage http://www.seamless.se/mozilla/ where example
code is posted.

The real bug is that the form.elements array is sorted incorrectly.  In
particular, the sort order _changes_ when you change an element's name.

See also bug 49951.

ccing jkeiser who may well have this fixed in his tree.  :)

Oh, and the workaround is to do:

var foo = document.xyz.elements[1];
foo.name = "whatever";
foo.value = "something";

this is at least related to bug 100499, if not a dup.  Not fixed in my tree.

In fact, this is dup of 121726 and not 49951 :-)
