What about this? '()' at the end of a JQuery statement terminates the
line (;). Also added a simple Function wrapper class. Treats 'this' as
a keyword.
Mind you, there is a good chance that these helpers are more difficult
that just writing jQuery code :)
So this:
print JQuery('#test').click(Function(JQuery("this").hide("slow")
(),'event'))()
print JQuery("p").bind("click",Function(JQuery("span").text("Click
happened!")(),'e'))()
Returns this:
$('#test').click(function(event){$(this).hide("slow");});
$('p').bind("click", function(e){$('span').text("Click happened!");});
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)
if isinstance(obj,Function): return str(obj)
return json.dumps(obj)
if not self.attr:
return ("$('%s')" % self.name).replace
("'this'","this")
args=', '.join([encode(a) for a in self.args])
return '%s.%s(%s)' % (self.name, self.attr, args)
def xml(self):
raise AttributeError
def __getattr__(self,attr):
def f(*args):
return JQuery(self,attr,*args)
return f
def __call__(self,*args):
if not args:
jq = str(JQuery(self))
jq = jq[3:]
jq = jq[:-2]
return jq + ";"
class Function:
def __init__(self,body,*args):
self.body = body
self.args = args
def __str__(self):
args=', '.join([str(a) for a in self.args])
body=self.body
return "function(" + args + "){" + body + "}"
