Better and more powerful:
class JQuery:
def __init__(self,name,attr=None,*args):
self.name=name
self.attr=attr
self.args=args
def __str__(self):
import gluon.contrib.simplejson as json
def encode(obj):
if isinstance(obj,JQuery): return str(obj)
return json.dumps(obj)
if not self.attr:
return '$("%s")' % self.name
args=', '.join([encode(a) for a in self.args])
return '%s.%s(%s)' % (self.name, self.attr, args)
def __getattr__(self,attr):
def f(*args):
return JQuery(self,attr,*args)
return f
print JQuery('test').set(1,'',{},JQuery('#12').val()).get(45)
