Dear Xerte-Community,
we are happily using Xerte for our e-learning, but recently our "provider" noticed and told us that we are serving quite an outdated version of jQuery. Xerte is currently coming with jQuery 1.9.1 which is from 2013, also the 1.x-branch is not maintained anymore for a few years. I guess it might not be such a security threat, but we are nevertheless interested in updating it.
I already tried replacing it with the newest version (3.5.1). Due to some incompatibility issues I also had to update jquery-ui (from 1.10.4) to 1.12.1.
At first glance most things seem to work, but all the buttons or rather their styles in the slides (e.g. forward, close pseudo-modal window) are broken. I.e. the button is missing its background-color and the button's title is printed behind the icon. In the former version the buttons get the class "ui-state-default" which takes care of the background. Also that text was embraced by a span that gets the class "ui-button-text" which has a massive negative indent making it invisible. Those elements/classes are not applied anymore using the current versions. I am not able to dig into the magic of jQuery(-ui) to find out why that is.
I managed to find a workaround for some of these issues by applying the needed styles to other selectors and maybe I will find some for the rest. But imo that isn't a very nice solution and might even have some undetected side-effects. I wonder if this isn't a known thing. I couldn't find anything about it in the forum, so I am posting the topic here.
Are there any plans from your side updating Xerte's version of those libraries? Or did someone in the community approach that problem and found a solution to it?
Thanks in advance!
Have a nice weekend and stay safe,
Jens
