I just want to make a jquery wrapper, and let people use it to write
jquery call on the server side in a python way ...
o is a object, imagine a widget : like a textarea or input box
"js" is a special attribut of "o", which will let you write javascript
for this object.
o=MyObject()
o.js.toggleClass("clean").hide()
When I will render the object to a http/html output : it will generate
something like (a javascript call): $("#idOfMyObject").toggleClass
("clean").hide();
It's all what I want in the real world.
I wouldn't do something like that (with the "()" tricks at the end on
the chain, because I don't find it really readable/natural)
o=MyObject()
o.js.toggleClass("clean").hide()()
The code I gave before (the JQueryCaller) was just my try to do what I
want ... If there is another way : I take ;-)
