Keep getting Uncaught TypeError: Cannot read property 'length' of null
on line 30
Removing that line fixed it.

This works
Update Discovered it wasn't working because I wasn't running on localhost
. Use the 0.0.2 Gist and run python -m SimpleHTTPServer
then navigate to localhost:8000
for a quick fix.
It's a security thing. Same thing happens if you expect protocol-less files (like Google's jQuery CDN) to work in file:///
context.
Having trouble with looping over .each
within jQuery and adding rules to $(this)
. Any ideas?
Update Nevermind, sorry to make you check this. I had to iterate over it and do a bunch of nth-child hackery. Works now. Thanks!
@corysimmons Thanks for the great suggestions. Didn't noticed that adding custom css-rules result in a security thing. I’ll roll up this piece of code next week and try to fix some things. Thanks again for your investigation! :-)
@yckart you're a life saver, thank you for this. Works like a charm, I'm using it in a resize function to readjust the height of a psuedo dynamically. Only question I had was it adds elements constantly is there anyway to clean up the previously added rules maybe with an additional removeRule call?
Thank you
I'm actually getting the following error:
Failed to parse the rule ' { background-image: http://192.168.56.10/wp-content/uploads/2015/06/tuscany-landscape_087-3840x350.jpeg }'.
Any ideas?
Edit: My mistake, the ":before" was missing on my call 😢
That's a great function. Is there any way to remove a previously applied ':after' style?
This is brilliant. liked subscribed, followed, etc.
Excellent, just what I needed! Thanks.
jQuery ? kkk I think that now you can remove the JQuery integration and modernize the JS
