I have created two functional Units on my application page. One comes along in a separate script, the other is embedded via script editor web part.

The external script is called fiirst all the time an I am priming jQuery using SP.SOD.registerSod('jquery', 'cdn-path/to/jquery');. When the script in my script Editor web part gets hit, I use SP.SOD.executeFunc('jquery', callback); to assure jQuery is loaded and I can execute my callback.

This does not work, though. When I reach the second call to SP.SOD.executeFunc() jQuery is already loaded, the callback just does not get called. However if I prime the same jQuery script again using SP.SOD.registerSod('jquery2', path/to/same/jquerycdn) everything works. What am I missing? How can I use jQuery across the scripts?

SOD (Script on Demand) and the MDS feature (Minimal Download Strategy) are not the easiest.

Not answering your question:

Use the Chrome Extension SharePoint Editor once

https://chrome.google.com/webstore/detail/sp-editor/ecblfcmjnbbgaojblcpmjoamegpbodhd?hl=en

to load jQuery with a UserCustomAction ScriptLink

That will load jQuery early on on every page in the SiteCollection

and save you some SOD & MDS headaches

  • Thank you for your engagement. I just don't get why the callback is not being called (please see question again, I added some Information). Can MDS be disabled?

  • Yes, MDS is a Site Collection feature. If you disable it and your callback works you know MDS is interfering (or better said: your SOD code is wrong) That is why using a ScriptLink to load jQuery always saves a whole lot of headaches

  • MDS is disabled. Currently I can only change individual site features, nevertheless the Feature is disabled on the desired site. Do you have any other ideas?

  • Not for your callback issue, had too many headaches with it in the past. Load jQuery the easy/fastest/safest way with that Chrome Extensions, if you want to scope it to the Web : see johnliu.net/blog/2015/12/…

  • Unfortunately I cannot use Chrome due to restrictions in the company. So I will use my Approach which is ugly but works. Thank you
