I was always a bit disappointed with the features, or rather non-features
of the html button, basically that all functionality has to be programmed
by hand.
I created a small class (and patched it into gluon.html) to make a button
and the respective JQuery script automatically. At this time the button
just works as a link to a page.
Would like to discuss if something like this makes sense, if it would make
more sense to add to the standard by expanding gloun.html.BUTTON to accept
'href' and behave accordingly...
class linkBUTTON(DIV):
"""
Pseudo Component to automatically generate JavaScript to execute on
click
"""
tag = 'linkbutton'
def xml(self):
"""
get attributes to generate the BUTTON, override _type to 'button'
if href is defined, create the respective JavaScript
"""
href = None
attr = {}
for key, value in self.attributes.iteritems():
if key == 'href':
href = value
continue
if key[:1] != '_':
continue
attr[key] = value
attr['_id'] = uuid4()
attr['_type'] = 'button'
result = BUTTON(self.components, **attr).xml()
if href:
result += '\n' +
SCRIPT("$('#%s').click(function(){window.location.assign('%s');});" %
(attr['_id'], href)).xml()
return result
