Hi everyone,
I spent an awful lot of time last night learning that if I instantiate
a widget and call it's render method that the javascript files
referenced with "javascript = JSLink(...)" are apparently not made
available in the serialized output (or any other way I could find) to
be loaded into the document's head (or anywhere else for that
matter)...But obviously the javascript is automatically loaded into the
head for you when you call a widget's display() method from the kid
template.
What I was trying to do was use render() to get a widget's HTML so that
I could shove it into a div at some point after a page had been loaded.
The HTML arrived just fine, but the JavaScript did not. This was
totally counter-intutive to me, so could someone please comment on why
render() doesn't include the JavaScript in a <script> tag as part of
the serialized output? I really am just trying to find a way to get a
widget's JavaScript so that it can be loaded into a page *without*
using display().
Is there an approved way to get at the actual javascript with an
existing mechanism, or is my assumption that it's a "good idea" to try
and do this for purposes of loading JavaScript into the head after page
load actually a bad idea?
An example (not tested, but serves the example)
def FooWidget(Widget):
template = "..."
javascript = [JSLink(...)]
def someMethodInController():
foo = FooWidget()
html = foo.render()
#how to get javascript out of FooWidget with instantiation of
FooWidget?
#I want to create a script element and shove it into a page after
page load
