Testing Javascript with Google Website Optimizer?

Can I test Javascript code in GWO? For example, how would I test:

$('#first_name_field').watermark('First name');

Ideally the person who tests different content doesn't have to enter开发者_StackOverflow lots of javascript, only the text they want to change... like "First name" above.

Yes you can test JS code in a MVT. You obviously can for a A/B test.

For the MVT case just wrap the GWO section code around html the script tags you want to test (you may need to add some).
