Re: lynx-dev two Forms queries

input type=button is a pure scripting element; it doesn't even have
to be on a form, although Netscape requires this.

input type=button is text, so alt is irrelevant.  In an ideal world,
this element would not be used unless the aspect of the application
that it implements fundamentally requires client side scripting.

If the button actually submits the form, they should have used 
input type=submit, and, in the unlikely event that they cared about
accessibility or security issues, should have coded it as

<input type="submit" name="xxx" value="yyy"
  onclick="javascript code; return false">

However, in that case, it is unlikely that the actions are specific to that
button, so they would be better off using onsubmit on the form, and 
returning false, to abort the submission, if the validation failed.

That depends on what "it" is.

Because POST is not required, or particularly expected, to be idempotent,
so a second POST to request $100,000 of dodgy mining stock could increase
your losses to $200,000.  (Well designed sites will use something like a
transaction serial number to detect a duplicate, but the protocol doesn't
require this.
