I disagree, the behavior seems controllable to me and I use it often.
In IE, a submit done via the enter key on a text input doesn't send
any of the <input type='submit' values back. On firefox, a submit
done with the enter key will send the first submit value. Just make
your default submit the first one and you can determine what to do
with your form. Here's a revised example:
form = FORM('blah blah',
INPUT(_type='text', _value='test',_name="test"),
INPUT(_type='submit', _value='Reset',_name="reset"),
INPUT(_type='submit', _value='Apply',_name="apply"),
INPUT(_type='submit', _value='Reset
all',_name="resetall"))
if request.vars.apply:
pass #clicked or enter was hit on FF
elif request.vars.reset:
pass #clicked
elif request.vars.resetall:
pass #clicked
else:
pass #enter was hit on IE, do apply
Maybe I'm missing something?
