munchkin.js - jQuery 1.9 compatibility

I think we have run into the 1.9 issue at Get Satisfaction. Does it make sense that the _mkto_trk cookie is being set but there is information on web page visits being logged in Marketo?

I did email Erik to find out about the beta availability.

Is there another way to manage the jquery conflict besides using the beta?

Thanks for any hints.

Rencently encountered this problem while using Marketo with jQuery 1.9.1.  I was able to get around it by using the jQuery migrate plugin.  Seems to have fixed it.  We actually used jQuery 1.10.1 with the 1.2.1 migrate plugin.

<script src="scripts/jquery-1.10.1.js" type="text/javascript"></script>
<script src="scripts/jquery-migrate-1.2.1.js" type="text/javascript"></script>

Try it out and post your results back here.

We just went through an exercise this week where we tried using the Beta Munchkin code. I just wanted to give folks a heads up. There is a bit of a catch-22 in using the beta.

The Beta is not backward compatible with the current Munchkin code. The standard Marketo landing pages use the current code. So the cookies on the website and those on the landing pages don't play nicely together leading to lack of tracking across all pages. If you replace the footer on the landing page templates with the Munchkin beta reference, then you loose the form pre-fill (and therefore progressive form) capabilities.

In the end, the company went back to the external web design company and paid them to redo the code so it would work with jquery 1.8. Of course, Ken's migrate answer above might have worked, but the web design company was already working on porting it backward.

We are using jQuery 1.9 and ran into problems with munchkin.js. We tried the jQuery migrate plugin but that caused other compatibility issues. I'd like to ask Marketo to hurry up with updating munchkin.js to be compatible with jQuery 1.9 and beyond, since this issue seems to be affecting quite a few clients.

One of our clients has jQuery 1.9.0 on their site and as we cannot see any anonymous leads in Web Analytics, I think we are suffering from the same issue here.

Is this just an issue when using the Asynchronous jQuery tracking code? Will downgrading to the Asynchronous (or even Simple) code work? Or is the only option (other than downgrading jQuery on the website) to include the migrate plugin?

Thanks in advance for any advice on this.

Hi Adam,

The version of Munchkin you use doesn't have any impact on jQuery compatibility. However, we do have a beta version which has been very stable and is compatible with 1.9. If you're interested, send me an email at erik@marketo.com and I'll give you the instructions.

Standard jQuery plugin should be provided to all as soon as possible. It's been about an year since jQuery 1.9 was released. 

Do you have a version of Marketo that doesn't require jQuery or doesn't download it's own version of jQuery?

We have jQuery 1.10.2 already on the page and Marketo is doing another http request for 1.7.1.

As a third party service I don't see why you need to do this or why you rely on a 3rd party library like jQuery.
We use optimizely for A/B testing and they let you build a version without jQuery bundled.

Is there any chance someone from Marketo can answer my question above please?

I received this response back from Marketo:

"Both the production and beta versions no longer have any dependency for jQuery" so the original poster shouldn't have any issues anymore.
