Thanks SN guru

The best way to point to a repository like that is to use a global UI script. As far as prototype, I use the standard Prototype API doc. You can find a link to it in the ‘Scripting Links’ section at the bottom of the page.

Mark,

Is there a way to include it but point to a CDN host (see: http://docs.jquery.com/Downloading_jQuery#CDN_Hosted_jQuery )? Since there are so many sites using jQuery now, it is likely the user will have a CDN version cached already.

Good point though about the need to be parsed by the browser. It’s exactly your point about the plugins (like jQuery UI – something I think would be very useful on the CMS side) that would be nice to leverage.

Having multiple javascript frameworks is not very desirable though. I just wish ServiceNow had standardized on jQuery – as that is what I’ve focused my attention on for the past couple years!

Guess I’ll be learning Prototype, now. :-)

Any suggestions on books / learning resources for Prototype?

There’s absolutely no problem with jQuery itself. In fact, it was included at one point in the default setup and is actually still included as an inactive UI script. Including it isn’t a big issue, but it does have an impact on client-side performance since that data needs to be sent to the client and then parsed by the browser’s javascript engine all the time. Any time you can limit the amount of script sent to the client you should. In this case, it’s a pretty large script library that you’re using so you should be especially careful about it. jQuery is great, and offers a lot of plugins that Prototype (and other libraries don’t), but I would only use it as a last resort. I love to use Prototype (which is the standard ServiceNow library) whenever I can.

You say: “I didn’t want to have to incorporate a separate API and deal with the loading the bulk of jQuery everywhere in the instance.”

Could you elaborate on what the concern is? Is it that difficult to incorporate the jQuery library, or point to a CDN hosted version?

With the fairly widespread adoption of jQuery in the last few years, I would think ServiceNow would want to include jQuery as base instance feature.

Awesome! Really cool stuff. Thanks Mark.

You should be able to check it out in your own instance too. It’s actually been around for a while now.
