Unfortunately, the above suggestion didn't work either!
If I try to open the JQuery .js file from the CDN in the web browser at work or whilst it is uploaded within SharePoint, I get an access denied message and if I download it to my pc and try to open it, it does not open in any program as it doesn't seem a program has been assigned to open it. I have to manually use 'Open With'. I am wondering how another software program the organisation uses manages to work with JQuery.
Anyhow, I have two other ideas and would be grateful if anyone could confirm if either were possible before I spend any time and effort working on something that cannot be achieved.
Add the JQuery .js file code to my actual webpage HTML file and refer to it.
Change any code in my webpage HTML file so that it is compatible with the older version of JQuery (1.x.x.).
I have found the following information at the following site and will give that a try also.
you use the migrate plugin to add backwards
compatibility to your newer version (1.9+). First replace your old
version of jQuery with the new one, then add a reference to the migrate
plugin. As if by magic, the deprecated elements removed in the more
recent version are restored and your existing code works:
Any advice would be appreciated.
