[pyjs-users] Calling a python object method javascript in pyjs

[Daniel Gonzalez]

Hi all,

I am completing my integration of a jQuery component with pyjs, which I 
will share with you as soon as is ready. We could add that to the examples 
dir.

Currently I am trying to pass a jQuery event up to my python code. The 
jQuery component is a Select2 element, which fires a change event whenever 
the user changes the content. I have verified that this is working by 
calling a pure javascript function, like this:

class MySelect2TaggingComponent(HTML):

...

    def setup_show(self):
        show = '''
         function show() {
                var e=parent.jQuery("<div 
style='background-color:yellow;'>change 
fired</div>");
                parent.jQuery("#%s").append(e);
                e.animate({opacity:0}, 100000, 'linear', function() { 
e.remove(); });
            };''' % (self.myid)
        myjs = '%s parent.jQuery("#%s").bind("change", show);' % (show, self
.myid)
        Logger("MySelect2TaggingComponent > setup_show", "Now calling JS: 
%s" % (myjs))
        JS(""" eval(@{{myjs}}) """)

As you can see here, what I am doing is to define a show function and bind 
it to the element change event. This works.

Now instead of calling the javascript show function, I want to call a pyjs 
"change" function, which will perform data processing and will send the 
data to the server.

I would like to define a change method like this:

class MySelect2TaggingComponent(HTML):


    def change(self):
        ...


How can I bind the javascript "change" event to this change method?

Thanks,
Daniel
