[pyjs-users] "JS function only supports constant strings"

[Daniel Gonzalez]

Hi,

I am trying to define the following component, which uses native javascript:

class MyTaggingComponent(HTML):


    def __init__(self, myid, values, width = 300):
        self.myid = myid
        values = ','.join(values)
        html =  '<p><input type="hidden" id="%s" style="width:%dpx" 
value="%s"/></p>' % (myid, width, values)
        HTML.__init__ (self, html)


    def final_setup(self, selected = '"red", "green", "blue"'):
        my_javascript = 'parent.jQuery("#%s").select2({tags:[%s]});' % (self
.myid, self.selected)
        JS(my_javascript)

I get a compile error: "JS function only supports constant strings".

This is a big problem, since, in order to reuse this component, I need to 
have variable content in the inline javascript. I have taken a look at the 
implementation of JS in pyjs/pyjs/src/pyjs/translator_proto.py, but it is 
not clear for me whether bypassing this restriction is possible, or how 
could it be done.

Could you suggest a workaround?

Thanks,
Daniel
