The constructor is still odd. Whoever created that example didn't use tw
idiomatic. And it in general seems to be a rather bad example, see below.
Use
class TestWidget(JUnit):
javascript = [test_js]
instead, if you must use JUnit.
> def update_params(self, d):
> super(TestWidget, self).upadate_params(d)
Superflous, can go.

The value is supposed to be passed via returnvalue from the controller.
I don't know what it is supposed to be for the JSUnit-widget, because
the whole page doesn't care to mention this.
So, do yourself a favor, and ditch that whole thing. It is official
docs, so it's sad that you stumbled over it. But it unfortunatly sucks.
Instead, try this:
class MyWidet(tw.api.Widget):
javascript = [JSLink(__modname__, "myscript.js")] # make sure that
the js is really under __modname__/myscript.js
template = "<div>Hello world!</div>"
engine_name = "genshi"
my_widget = MyWidget("test")
@expose("the.template")
def action(self, ...):
c.my_widget = my_widget
return dict
And in "the.template.html", do
${c.my_widget.display()}
This should work, render a jslink into the source, and the "hello
world". From there on, try to expand, by e.g. using add_call inside
"update_params" to render a piece of js that invokes code from myscript.js.
