Fixes #87

[pasevin]

This is my attempt at fixing this long-standing issue. It works for my needs without issues so far.
I've utilized MutationObserver for observing DOM node additions. And replaced Django render method with a javascript initialization instead.

This looks good to me - just two comments:

1. Can you remove the imports of safestring, get_language and simplejson as json, since they're no longer used? (That'll fix the flake8 checks)
2. My JavaScript knowledge isn't good enough to know what browsers this will work in - do you know? From a quick glance, I think MutationObserver is the main thing here, but that looks to be fairly widely supported. Anything else I'm missing?

Thanks for your efforts on this - they're much appreciated!

[pasevin]

Cool!

1. Done.
2. I went with MutationObserver vs DOMNodeInserted, which is used more widely and easier to implement, but looking forward is deprecated. I think this is the only reasonable way to go.

Fantastic - thanks @pasevin! All going well I'll test this and merge it tonight.

Hi @pasevin - I can't get this to work locally - targetNode on line 7 of recurrent-widget.init.js is always null. Where does the class grp-content-container come from? I can't see it anywhere in Django's source. I've tested Django 2.1.7 and 1.11.14. Any ideas?

[pasevin]

My bad! It's a native django-grappelli class name. I will fix it asap. I knew I will screw this up in some way :))

[pasevin]

Should be working now. I checked on the vanilla Django theme.

[dominicrodger]

Awesome - thanks @pasevin. I'll take another look as soon as I can (hopefully by the end of the week).

I am trying to use this package for my recurrence.
I am getting the following error:

recurrence-widget.init.js:7 Uncaught TypeError: Failed to execute 'observe' on 'MutationObserver': parameter 1 is not of type 'Node'.
at HTMLDocument. (recurrence-widget.init.js:7)
at i (jquery.min.js:2)
at Object.fireWith [as resolveWith] (jquery.min.js:2)
at Function.ready (jquery.min.js:2)
at HTMLDocument.J (jquery.min.js:2)

The node with the id "container" is no where to find.
Where exactly is the above node?

Just a note: I am using version 1.9 as I am still on Python 2.7 and django 1.11

i get the same
recurrence version 1.10.2/django 2.2.2/python3.7.7
any thoughts ?
