Disabled JavaScript and JS-based extensions in Google Chrome

Some sites I visit tend to use heavy JS scripting causing some lags if they are open in multiple tabs simultaneously. I would really love to disable JS for all of them that might not require JS to work properly. However, I've also noticed that disabling JS for a site causes installed extensions background pages (not sure about the proper term here) not work, hence I caot use such extensions.

Is it possible to disable JS for some sites and let JS-based extensions at those sites in Google Chrome?
