If I bind with MySelect2TaggingComponent().change (as explained in the
stack overflow answer) I would be creating a
new MySelect2TaggingComponent object, which I do not want. I want to bind
to the change method of the object which has defined the whole Select2
elements. That is why I am trying with self["change"] and this.change
(which I guess refer to the same thing)
On the other hand, I do not know how to match the concept of anonymous
function in javascript to my MySelect2TaggingComponent.change method.
"function { ... }" is an anonymous function, which I can not relate to the
change method.
Finally, I have tried binding to window.change, like this:
myjs = 'parent.jQuery("#%s").bind("change", window.change);' % (self.myid)
There are no errors, but the change method is not triggered :(
Regarding pyjd: I have tried, but since I am using JS statements, it is
failing early.
I thank you very much for your support and I understand that you are
probably very busy!
Nevertheless, if you ever get the time to take a look at my example, it
would be very helpful. I copy paste here the commands that you need:
mkdir xxx ; cd xxx
git clone [email protected]:gonvaled/pyjs.git
cd pyjs/examples
python jquery-select2 --download
Thanks and regads,
Daniel
